National Traffic Scorecard
2008 Annual Report
Executive Summary In June 2008, INRIX published the groundbreaking INRIX National Traffic Scorecard (available at http://scorecard. inrix.com). Using data from 2007, the initial Scorecard provided a comprehensive and consistent overview of where and when congestion exists on the major roads in America’s top 100 metropolitan areas. This 2008 Scorecard, available less than 60 days after the end of 2008, summarizes the state of congestion in 2008 across the America and how it changed versus 2007. Like most other aspects of society, 2008 was no ordinary year in terms of traffic or congestion, for several high profile reasons: •
Fuel prices. 2008 brought unprecedented fuel price volatility, with a massive and consistent increase through the first half of 2008 followed by an even greater plunge in prices during the second half of 2008. Overall, average fuel costs in 2008 were up nearly 20% from 2007.
•
Unemployment. Peak hour traffic is largely associated with commuter traffic, people traveling to and from jobs. 2008 saw a steady increase in the nation’s unemployment rate, with every month being higher than the comparable month in 2007.
•
Traffic Volume. The combination of higher fuel prices and a struggling economy yielded a consistent decline in overall traffic volume. Official figures from the Federal Highway Administration (FHWA) show that the first eleven months of 2008 were substantially below 2007 levels, with percentage reductions never before recorded. Overall, FHWA reported a 3% reduction in vehicle miles traveled on the types of roads analyzed in this Scorecard.
Leveraging tens of billions of data points from 2006, 2007 and 2008 collected and archived by the INRIX Smart Dust Network, this Scorecard publishes the most up-to-date information regarding overall congestion and specific bottlenecks on the major roadways of urban America. By analyzing over 30,000 road segments on more than 47,000 miles of the major highways in the nation’s 100 largest metropolitan areas, this report informs the ongoing debate of one of the nation’s most frustrating and intractable issues: urban traffic congestion. How bad is congestion? Where is it worst? How has it changed? What can be done about it? This Scorecard provides the most comprehensive and timely national scale glimpse of the answers to these questions.
National Congestion Results and Trends Overall, the nation’s peak period time Travel Time Index (TTI) for 2008 was 1.09. This means that during peak driving times a random traveler on a random trip on the roads analyzed took 9% extra time, on average, than

Executive Summary if there was no congestion. This represents a decrease in the Travel Time Index of 3.5% from 2007; more than reversing the increase of 1.9% between 2007 and 2006 (see Figure ES-1).

Figure ES-1: National Travel Time Index by Year
When considering the change in congestion – which is the extra amount the Travel Time Index is above 1.00 (a Travel Time Index of 1.00 would define an instance when no congestion existed and a trip was taken entirely in free flow conditions) – the decrease is even more startling: peak hour congestion on the major roads in urban America decreased nearly 30% in 2008 versus 2007. As the details in the Scorecard highlight, other key results include: •
National congestion was lower every hour of every day in 2008 versus 2007 – between 15% and 60% lower depending on the hour and day.
•
Friday from 5 to 6 PM remained America’s most congested hour of the week, although the Travel Time Index fell 23% from 1.26 to 1.20, just ahead of Thursday 5 to 6 PM, which had a TTI of 1.19 in 2008.
•
Wednesday saw the biggest drop in congestion, with a 31% overall decrease in peak periods.
•
Each weekday morning, peak hour congestion dropped much more than its corresponding evening peak hour congestion (See figure ES-2).
•
National congestion levels were essentially the same when comparing the first and second halves of 2008, thus it seems that higher fuel prices in early 2008 and the slower economy later in the year netted the same drop in overall congestion.

•
Congestion in off peak hours (outside of the AM and PM weekday commuting times) decreased by more than 36%, substantially outpacing the significant drop in peak hour congestion.
As expected, the health of the economy and higher average fuel costs led to decreased congestion – but the scale of the decrease, roughly 30%, is startling.
Metropolitan Comparisons and Trends
A 3% drop in vehicle miles traveled resulted in a 30% drop in peak period congestion in 2008.
While no region of the country was spared volatile fuel prices and some amount of economic stress, some regions clearly have had a better or worse relative impact. Couple these differences with variations in overall highway construction and maintenance activity – a key contributor to recurring regional congestion as highlighted in later sections – and the reduction in overall congestion varied widely by metropolitan area. Figure ES-3 highlights the nation’s top 10 regions in terms of overall congestion, Travel Time Index (which normalizes the congestion data by road miles analyzed in each region, giving the fairest consumer-oriented view of congestion in a region), the biggest drops in Travel Time Index between 2007 and 2008, and the most congested “worst hour” rankings.

In almost all cases, when regions moved up a list, it was due to less congestion reduction than its peer regions in that category. For example, despite a 20% drop in congestion, the Minneapolis-St. Paul region moved from 13th to 10th in total congestion, passing Atlanta, Miami, and Philadelphia.
•
Los Angeles moved ahead of Honolulu with the highest metropolitan Travel Time Index. Honolulu’s 34% drop in congestion lowered its Travel Time Index from 1.45 to 1.31, where Los Angeles’ 23% drop lowered its TTI from 1.44 to 1.33

Executive Summary Bottlenecks Nearly 31,000 individual road segments were analyzed to determine the extent and amount of average congestion each had in 2008. More than 6000 segments registered at least one hour of the week when one can expect to travel at less than half the free flow or uncongested speed. As expected based on the overall congestion data, the number and intensity of bottlenecks were down considerably from 2007. Overall 28% fewer segments had at least one hour of congestion in 2008. Figure ES-4 details the drop for each threshold.

The nation’s worst bottleneck remained the same, a westbound stretch of the Cross Bronx Expressway/I-95 leading up to and including the Bronx River Parkway exit 4B interchange. As in 2007, it was congested an astounding 94 hours of the week, but the average speed while congested rose in 2008 to 11.2 MPH from 9.8 MPH.
ES-5
National Traffic Scorecard
2008 Annual Report
Executive Summary One third of the top 100 bottlenecks in 2007 were not in the top 100 in 2008. Five of the road segments that dropped out of the top 100 fell outside of the Top 1000 – four of these were on the Dan Ryan Expressway in Chicago, which was part of a multi-year construction project that ended in 2007. As in 2007, more than half of the nation’s top 1000 bottleneck segments (see Figure ES-5) were in the New York, Los Angeles and Chicago areas. Roughly one fourth of the nation’s top 1000 bottlenecks in 2007 fell out of the top 1000 in 2008. Again, much of the volatility appears tied to the beginning or ending of long-term construction or maintenance projects. Overall, the top 1000 bottlenecks in 2008 were congested an average of 26 hours each week (versus 31 hours in 2007), with an average speed while congested of 18 MPH (versus 16 MPH in 2007).

National Traffic Scorecard
2008 Annual Report
Executive Summary Conclusions With a new presidential administration, the just-passed stimulus package, and the upcoming expiration of SAFETEA-LU, this is an important year for transportation issues. The Scorecard has generated some relevant findings to assist in both national and regional debates, including: •
Volume changes have much bigger impacts under congested conditions. FHWA data shows that in 2008, traffic on “urban interstates” was down 3% nationwide compared to 2007. This has translated to a nearly 30% reduction in peak hour congestion and an even larger 36% drop in off-peak congestion. This illustrates multiple issues: —— Demand management can have sizeable impact on congestion, even if total volume changes are modest. Massive increases in fuel prices had effects similar to policy initiatives under consideration such as variable pricing, managed lane strategies and better travel information. When a road network is at capacity, adding or subtracting even a single vehicle has disproportionate effects for the network. This phenomenon has been well known for a long time, but this data illustrates it in real-world terms on a nationwide basis. —— While the drop in congestion is welcomed in general, the primary root causes – high fuel costs and lagging economic activity – are not. Ideally, the nation’s economy will turn around in short order and fuel prices will remain moderate. If so, we can expect congestion to largely snap back to levels comparable to 2007 levels or worse. While we all should cheer the reduction in congestion in 2008, we should be under no illusion that this is permanent. We must still continue to focus energies on policies and methods to tackle congestion. When the economy is growing again, congestion will likely move to the front and center again as the nation’s primary surface transportation problem.
•
The linkage between work zones and bottlenecks. The significant percentage of bottlenecks that appear to be related to work zones underscores the need to focus on managing work zones in ways that mitigate congestion. With the upcoming stimulus spending, the amount of work zones is likely to grow to numbers never before seen. Further, there is strong desire to move as quickly as possible in getting highway projects underway. Proper work zone planning will be essential if we are to keep the nation’s highways from becoming a parking lot.

National Traffic Scorecard
2008 Annual Report
Introduction In June 2008, INRIX published the groundbreaking INRIX National Traffic Scorecard.1 Using data from 2007, the initial Scorecard provided a comprehensive and consistent overview of where and when congestion existed on the major roads in America’s top 100 metropolitan areas. This 2008 Annual Report of the Scorecard, available less than 60 days after the end of 2008, summarizes the state of congestion in 2008 across the U.S.
2008: A Blip or a Trend? Historically, traffic volumes and congestion, like the size of the economy and the population have tended to consistently rise year after year. While the occasional recession or fuel price spike may halt the upward march of traffic, it has almost always been only a small and temporary pause. 2008 was different. As one might expect, in terms of traffic and congestion, 2008 was no ordinary year, on several fronts: Fuel prices. 2008 brought unprecedented fuel price

So, 2008 wasn’t just another year where things generally get somewhat worse in terms of congestion. Having the nation’s most extensive traffic data repository, with more than three times the data points to leverage in 2008 versus 2007, has enabled INRIX to provide this unique, timely and important report summarizing how these unprecedented circumstances affected traffic congestion in 2008.
INRIX’s Unique and Timely Traffic Data Archive In 2006, INRIX introduced the Smart Dust Network, the first truly national traffic data collection network. The Scorecard has established an equally revolutionary approach to measuring the nation’s traffic congestion problem. Leveraging tens of billions of data points from 2006, 2007 and 2008 collected and archived by the Smart Dust Network, this report publishes the most up-to-date information regarding overall congestion and specific bottlenecks on the major roadways of urban America. By analyzing over 30,000 road segments on more than 47,000 miles of the major highways in the nation’s 100 largest metropolitan areas, this report informs the ongoing debate of one of the nation’s most frustrating and intractable issues: urban traffic congestion. How bad is congestion? Where is it worst? How has it changed? What can be done about it? This Scorecard provides the most comprehensive and timely national scale glimpse of the answers to these questions.

National Traffic Scorecard
2008 Annual Report
Methodology The INRIX National Traffic Scorecard draws from several existing approaches to calculating traffic congestion and leverages new methods made possible by INRIX’s proprietary data. This section provides background on the raw data and the processes used.
Source Data The raw data comes from the historical traffic data warehouse of the INRIX Smart Dust Network. Since 2006, INRIX has acquired tens of billions of discrete “GPS-enabled probe vehicle” reports from vehicles traveling the nation’s roads – including taxis, airport shuttles, service delivery vans, long haul trucks, and consumer vehicles. Each data report from these GPS-equipped vehicles includes the speed, location and heading of a particular vehicle at a reported date and time. INRIX has developed efficient methods for interpreting probe vehicle reports that are provided in real-time to establish a current estimate of travel patterns in all major cities in the United States. These same methods can aggregate data over periods of time (annually in this report) to provide reliable information on speeds and congestion levels for segments of roads. With the nation’s largest probe vehicle network, INRIX has the ability to generate the most comprehensive congestion analysis to date, covering the nation’s largest 100 metropolitan areas.
Metropolitan Area The US Census Bureau definition of Core Based Statistical Areas (CBSA)3 is used to define metropolitan areas. This report uses the latest 2007 census estimates4 to identify the top 100 areas.
Roads/Segments Analyzed This report focuses on the major limited access roads in the top metropolitan areas in the United States. In all of its products, INRIX utilizes an industry convention known as “TMC location codes” developed and maintained by the nation’s leading electronic map database vendors to uniquely define road segments. The typical road segment is the interchange and the portion of linear road leading up to the interchange across all lanes in a single direction of travel. The length of a segment will depend upon the length of the distance between interchanges. For this report, over 47,000 road miles in nearly 31,000 discrete road segments have been analyzed (see Figure 4).

Figure 4: Roads Analyzed in Scorecard Are Indicated in Green
Analysis Time Period The focus of this report is the calendar year 2008. In some cases, calendar year 2006 and 2007 data is utilized to enable year over year comparisons.
Road Segment Data There are two key building blocks for the different analyses included in this report: •
Reference speed (RS): For each road segment, all probe vehicle reports obtained in overnight hours (where congestion is usually unlikely) in 2008 are analyzed. The 85th percentile of those data points is identified as the “reference speed” for that particular road segment. This is typically the speed of “free flow” traffic if and when no congestion exists. Each segment has a single reference speed.
•
Hourly average speed (HS): All probe vehicle reports for each road segment are grouped by hour of day, day of week (e.g. Monday from 3 to 4pm) and an “average speed” for each time slot is established for each road segment. Thus, each segment has 168 corresponding hourly average speed values – representing 24 hours of each day muliplied by the seven days in a week.

National Traffic Scorecard
2008 Annual Report
Methodology Overall Congestion Metrics – Regional and National To assess congestion for a CBSA, INRIX utilizes several concepts that have been used in similar studies. •
Travel Time Index (TTI): TTI is the ratio of peak period travel time to free flow travel time. The TTI expresses the average amount of extra time it takes to travel in the peak relative to free-flow travel. A TTI of 1.3, for example, indicates a 20-minute free-flow trip will take 26 minutes during the peak travel time periods, a 6-minute (30 percent) travel time penalty.5 For each road segment, a TTI is calculated for each hour of the week, using the formula TTI = RS/HS.
•
“Peak Hour” Congestion: To assess and compare congestion levels year to year and between CBSAs, only “peak hours” are analyzed. Consistent with similar studies, peak hours are defined as the hours from 6 to 10 AM and 3 to 7 PM, Monday through Friday – 40 of the 168 hours of a week.
For each Metropolitan Area, an overall level of congestion is determined for each of the 40 peak hours by determining the extent and amount of average congestion on the analyzed road network. This is easy to compute once TTI’s are calculated for each segment:
STEP 1: For each of the 40 peak hours, all road segments analyzed in the CBSA are checked. Each segment where the TTI > 1 is contributing congestion, and it is analyzed further. STEP 2: For each segment contributing congestion, the amount the TTI is greater than 1 is multiplied by the
length of the segment, resulting in a congestion factor. STEP 3: For a given hour, the overall metropolitan congestion factor is the sum of the congestion factors
calculated in STEP 2. STEP 4: To establish the Metropolitan Travel Time Index for a given hour, the metropolitan congestion factor
from STEP 3 is divided by the number of road miles analyzed.
STEP 5: A peak period Metropolitan Travel Time Index is determined by averaging the hourly Metropolitan Travel Time Indices from STEP 4.
New for this 2008 Annual Update, monthly Travel Time Index values have been calculated for each CBSA and nationally as well and are included in subsequent sections.

National Traffic Scorecard
2008 Annual Report
Methodology Bottlenecks With the unique ability to examine in detail nearly 31,000 urban highway road segments, INRIX identifies the specific locations in each metropolitan area – and can compare locations across the country – that are consistently congested. These are “bottlenecks.” 6 Congestion – and how to measure it – can be in the eye of the beholder. Is congestion defined as how bad a road segment is at its worst or is it how often the segment gets “congested” (and what is the threshold for “congestion” anyways – tapping the brakes, stop and go conditions, etc.)? INRIX has developed a method that combines both the amount of time a road segment is congested with the intensity of congestion during those periods. The process used to analyze each of the nearly 31,000 road segments is as follows: •
The same RS and HS values are utilized as in the overall congestion by metropolitan area portion of the study;
•
All 168 hours of the week are considered, not just the 40 “peak hours.” As will be evident in the data, severe bottlenecks aren’t just limited to peak hours;
•
For each hour of the week that the average speed is less than 50% of the reference speed (RS), the hour is considered “congested;”
•
For all “congested” hours, the average intensity of the congestion is determined by establishing an average travel time ratio;
•
The total bottleneck factor equals the number of hours of congested by the average travel time ratio.
•
Each road segment’s bottleneck factor can be compared with others in a metropolitan area and against all bottlenecks nationally. It can also be compared year-to-year, as we have in this Scorecard.
From the Federal Highway Administration: Traffic Bottleneck: (Simple definition) A localized constriction of traffic flow. (Expanded definition) A localized section of highway that experiences reduced speeds and inherent delays due to a recurring operational influence or a nonrecurring impacting event.

National Congestion Results and Trends The methodology used to measure overall congestion and to establish the metropolitan Travel Time Index for each of the weekly 40 drive time hours enables the calculation of overall national congestion metrics, by hour, by morning and evening drive time, by day and overall. New for the 2008 Annual Update is the inclusion of monthly data as well.
Overall Travel Time Index and Congestion Overall, the nation’s peak period time Travel Time Index for 2008 was 1.09. This means that during peak driving times7 a random traveler on a random trip on the roads analyzed took on average 9% extra time than if there was no congestion. This represents a 3.5% decrease in the Travel Time Index from 2007 – more than reversing the increase of 1.9% between 2007 and 2006 (see Figure 5).

Figure 5: National Travel Time Index by Year
When considering the change in congestion – which is the extra amount the Travel Time Index is above 1.00 (a Travel Time Index of 1.00 would define an instance when no congestion existed and a trip was taken entirely in free flow conditions) – the decrease is even more startling: peak hour congestion on the major roads in urban America decreased nearly 30% in 2008 versus 2007. So, if the average amount of delay time per traveler in 2007 was 44 hours8, the approximate reduction in delay per traveler in 2008 was 13 hours. This means the average traveler “saved” 13 hours in time off the roads in 2008 versus 2007. The data also reveal that off peak hours – the 128 hours of the week not analyzed in the peak driving hours – saw a larger percentage drop in congestion than the peak hours, down roughly 36% versus 2007.
Peak period drive time hours are 6 – 10 AM and 3 – 7 PM, Monday through Friday. See Texas Transportation Institute’s 2007 Urban Mobility Report, where the average annual delay per travel in 2005 in the 85 “large areas” studied was 44 hours (http://mobility.tamu.edu/ums/).

2008 Annual Report
National Congestion Results and Trends National Travel Time Index by Hour and Day of Week A national perspective shows the Travel Time Index/overall congestion for every hour and day of the week was well below its level in 2007. Figure 6 shows the 2008 National Travel Time Index by the hour and day of the week (note: “5 PM” in the figures refers to the 5-6 PM hour, etc.). Figures 7-13 compare National TTI for each day and hour between 2007 and 2008. Noteworthy findings: —— Friday from 5 to 6 PM remained America’s most congested hour of the week, although the Travel Time Index fell 23% from 1.26 to 1.20, just ahead of Thursday 5 to 6 PM, which had a TTI of 1.19 in 2008. —— Wednesday saw the biggest drop in congestion, with a 31% overall decrease in peak hours. —— Each weekday morning, peak hour congestion dropped much more than its corresponding evening peak hour congestion (See figure 14).

National Congestion Results and Trends Travel Time Index by Month New for this update is the inclusion of monthly Travel Time Index calculations. Each metropolitan area summary page now includes the region’s TTI by month. This also allows the calculation of a national TTI for each month. Figure 15 shows the changes in national TTI from month-to-month.

Figure 15: 2008 National Travel Time Index by Month
It should be noted that traffic volumes have historically varied significantly from month-to-month over the course of a calendar year. It is anticipated that monthly TTI – both nationally and in each region – will exhibit similar characteristics, meaning that over time, it will be more meaningful to compare the same month from year to year, than the current month to the last month. In 2008 however, given the dramatic change in circumstances from the first half to the second half of the year, it is meaningful to compare the average Travel Time Index from the first 6 months to the second 6 months of 2008. Interestingly, likely for very different reasons, the Travel Time Index for each half of 2008 is virtually identical: 1.093 for 1H 2008 versus 1.095 for 2H 2008.

Metropolitan Rankings Table 1 provides market to market comparisons of metropolitan areas. As there are several different ways to quantify congestion, the table has many columns. The print version of the table is sorted on Peak Hour Congestion. The online version of this table, located at http://scorecard.inrix.com, can be sorted by all columns to show rankings based on each parameter. Included in Table 1 are: •
Metropolitan Area details, including the official CBSA name, the total population and national rank and the number of road miles analyzed (which varies based on the size of the region and the extent of its limited access road network).
•
Peak Hour9 Congestion results and rankings, including the 2008 ranking and congestion level, referenced in terms of the percentage of the nation’s worst overall congestion (Los Angeles), the 2007 ranking, the change in regional ranking and the percentage change in overall congestion from 2007 to 2008.
•
Peak Hour Travel Time Index results and rankings, including the 2008 Travel Time Index and ranking, the 2007 ranking and the change in regional ranking and the percentage change in TTI from 2007 to 2008.
•
“Worst Hour” results, including worst day/time for congestion in the region for 2008, the Travel Time Index during that hour and the comparison rank of the Travel Time Index to the worst hour TTI of other regions.
•
Off-Peak and Total Congestion, including the 2008 ranking and congestion level, compared to the worst region for off peak hours (the 128 non-peak hours each week) and all hours/days (peak hours and off peak hours), and the percentage of overall congestion that occurred in peak versus off peak hours in 2008.
Figure 16 shows several “top 10” lists derived from the data in Table 1.
Peak period drive time hours are 6 – 10 AM and 3 – 7 PM, Monday through Friday.

National Traffic Scorecard
2008 Annual Report
Metropolitan Rankings •
In almost all cases, when a region moved up a list, it was due to less congestion reduction than its peer regions in that category. For example, despite a 20% drop in congestion, the Minneapolis-St. Paul region moved from 13th to 10th in total congestion, passing Atlanta, Miami, and Philadelphia.
•
99 of the 100 regions saw congestion levels decrease. Baton Rouge, LA, with a 6% increase in overall congestion, was the only region with an increase from 2007, shooting it up the metropolitan rankings from 47th to 33rd in overall congestion.
•
Los Angeles moved ahead of Honolulu with the highest metropolitan Travel Time Index. Honolulu’s 34% drop in congestion lowered its Travel Time Index from 1.45 to 1.31, while Los Angeles’ 23% drop lowered its TTI from 1.44 to 1.33.
•
The largest drops in congestion by percentage are dominated by metropolitan areas of less than 1 million people. Many had modest congestion in 2007 when compared to larger regions, so modest drops in congestion resulted in larger percentage drops than the larger areas.
•
The largest drops in congestion and rankings of the “big cities” included the Atlanta, Miami, Detroit, San Diego and the “Inland Empire” (Riverside-San Bernardino-Ontario) region of California, all having drops in peak hour congestion of at least 36% from 2007.
Overall, while congestion clearly dropped across the country, this drop was not uniform across all regions, and depending upon where one lives or when they travel, congestion – though likely better than in 2007 – was still substantial.

National Traffic Scorecard
2008 Annual Report
Bottlenecks Nearly 31,000 individual road segments were analyzed to determine the extent and amount of average congestion each segment had in 2008. More than 6000 segments contained at least one hour of the week where one can expect to travel at less than half the uncongested speed. Based on the overall congestion data, the number and intensity of bottlenecks was down considerably from 2007. Overall 28% fewer segments had at least one hour of congestion in 2008. Figure 17 details the drop for each threshold. Also, 25 metropolitan areas had no significant bottlenecks (defined as congested four or more hours per week), up from 17 areas in 2007.

2008 Annual Report
Bottlenecks in 2007, it was congested an astounding 94 hours of the week, but the average speed while congested rose in 2008 to 11.2 MPH from 9.8 MPH. Eight of the 10 worst bottlenecks in 2007 remained in the top 10 for 2008, with the other two moving to 11th and 16th places. They were replaced in the top 10 by 2007’s 12th and 16th worst bottlenecks. Beyond the top ten, the “mobility” of the bottlenecks up and down the list was significant. Thirty-three of the top 100 bottlenecks in 2007 were not in the top 100 in 2008. Five of those segments that dropped out of the top 100 fell outside of the Top 1000. Quick review suggests a strong correlation between work zone activity and bottlenecks. As an example, a single bottleneck in the 2007 top 100, I-35E Southbound at I-694 in MinneapolisSt. Paul which ranked 63rd worst in 2007, had no hours in 2008 where the average speed was half or less of free flow speed. This area was a work zone associated with a multi-year “Unweave the Weave” project10 that has significantly improved the I-35E/ I-694 Interchange. Similarly, the other four segments that dropped from the top 100 in 2007 to outside the top 1000 in 2008 were segments of the Dan Ryan Expressway in Chicago that was part of a multi-year construction project that ended in 200711. Figure 18 summarizes the collective improvement of congestion in the nation’s worst bottlenecks. On average, these bottlenecks saw 3 less hours of congestion and saw speeds increase nearly 2 MPH. When factoring in fewer delays in these bottlenecks for less periods of the week, the nation’s 100 worst were about 16% less congested in 2008 than in 2007.

2008 Annual Report
Bottlenecks In 2008, 252 of the nation’s top 1000 bottlenecks in 2007 fell from the top 1000. Again, much of the volatility appears tied to the beginning or ending of construction or maintenance projects. The highest ranking addition to the 2008 list of bottlenecks that did not have even one average hour of “congested” conditions in 2007 was Ronald Reagan Freeway/SR 118 Eastbound at Stearns Drive in Ventura County, California. Ranked 154th overall in 2008, this bottleneck was created as part of a widening project in the area that began in March 2008 and is expected to be completed in mid-2009.12 Two other adjacent road segments also moved from no recurring congestion in 2007 to the top 1000 bottlenecks in 2008. Overall, as Figure 21 highlights, the top 1000 bottlenecks in 2008 were congested an average of more than 5 hours less each week, with an average speed increase of 1.4 MPH than those in 2007, leading to a roughly 23% drop in congestion impacts of the top 1000 bottlenecks.

Figure 21: Average Conditions of Nation’s 1000 Worst Bottlenecks
When examining the bottlenecks on a national basis, several conclusions can be drawn: •
Bottlenecks aren’t just a mega city issue. While a majority of bottlenecks are in Los Angeles, New York and Chicago, 41 of the 100 areas had at least one bottleneck in the top 1000 in 2008.
•
While down from 2007, more than 1000 road segments are congested, on average, at least 10 hours a week. Add in an accident, bad weather or a special event and these locations, though likely better on average than in 2007, can still gridlock quickly. Even with the “perfect storm” of conditions in 2008 that generally reduced congestion, there is still no margin for error on a large portion of our major highway network.
•
Construction, while helping in the long run, can create long-term temporary bottlenecks. As the “stimulus package” signed into law in mid-February 2009 jump starts “shovel-ready” projects nationwide, planners of those projects should heed these results as evidence that careful maintenance of traffic planning should not be short-changed, as what appear as temporary bottlenecks from a project perspective can lead to recurring congestion for weeks, months or even years.

Bottlenecks •
Several of the individual road segments identified as bottlenecks are connected to other segments also identified as bottlenecks – basically corridor bottlenecks. While these may be associated with an upstream interchange or geometric configuration issue, the length of these bottlenecks can be long and troubling for drivers.
•
Moderate congestion can and does disappear. Perhaps since the birth of the interstate system, the national psyche has been conditioned to accept that congestion is bad, getting worse with little or no chance to stop it. More than 2000 road segments that had at least one hour of congestion in 2007 had no identified recurring congestion in 2008, clearly demonstrating that the march towards gridlock can be reversed. While the causes of the decline in 2008 – lower demand due to fuel prices and lower economic activity – aren’t the most desired ways to achieve these reductions, it does show that it is possible reverse the trend. Policies that can influence demand at the right places and times may be able to show the same benefits.

National Traffic Scorecard
2008 Annual Report
Scorecard Relationship with Other Studies As one would expect for an issue as relevant to our daily lives and economic system as traffic congestion, there are many recently published studies on the issue. This Scorecard expands upon and complements these reports. The following list is but a few of the notable recent reports: —— 2007 Annual Urban Mobility Report (Texas Transportation Institute): http://mobility.tamu.edu/ums/ —— Unclogging America’s Arteries: Effective Relief for Highway Bottlenecks 1999-2004 (American Highway Users Alliance): http://www.highways.org/pdfs/bottleneck2004.pdf —— Building Roads to Reduce Traffic Congestion in America’s Cities: How Much and at What Cost? (Reason Foundation): http://www.reason.org/ps346/state_by_state_congestion.pdf —— Freight Performance Measurement: Travel Time in Freight-Significant Corridors (Federal Highway Administration): http://ops.fhwa.dot.gov/freight/freight_analysis/perform_meas/fpmtraveltime/index.htm —— America’s Most Congested Cities (Forbes Life Magazine): http://www.forbes.com/2008/04/10/congestedcommute-cities-forbeslife-cx_mw_0410realestate.html —— Where the Commuting Nightmares Are (bizjournals): http://www.bizjournals.com/edit_special/56.html —— The Road…Less Traveled: An Analysis of Vehicle Miles Traveled Trends in the U.S.: http://www.brookings. edu/reports/2008/~/media/Files/rc/reports/2008/1216_transportation_tomer_puentes/vehicle_miles_ traveled_report.pdf While the Scorecard shares some common elements with these reports, it also has several unique features. •
Common elements —— The Scorecard adopts the common convention of peak period drive time hours of 6 – 10 AM and 3 – 7 PM, Monday through Friday. —— The Travel Time Index concept is now a standard metric to measure conditions relative to uncongested, free flow situations.
•
Unique features —— This report is based on data, technology and processes that have been designed to optimize very quick turnaround times between the end of the data collection period and the publishing of the Scorecard. Many of the reports utilize data that is many months or years old when published. —— The Scorecard is completely based upon real data – tens of billions of data points from real consumer and commercial vehicles traveling on real road segments. It is not limited by sensor coverage nor is it an interpolation of data.
26
National Traffic Scorecard
2008 Annual Report
Scorecard Relationship with Other Studies —— This is the first analysis to go to the detailed road segment level nationwide; it is also the first to look in depth by hour and day nationwide. Further, this report offers a unique opportunity to see trending by time, region or specific road segment. Given the myriad of ways to calculate congestion and the wide range of raw data that is utilized, it is natural that different reports can have different results, rankings and indexes. When comparing differences between the Scorecard and other reports, it could be due to one or more of the following reasons: •
Many of the reports weight results by traffic volume and/or factor in the number of lanes on roadways; the Scorecard does not.
•
Travel Time Index calculations are from a road user perspective based on complete random trips, not weighted by volumes, lane miles, or origin/destination weighting.
•
Travel Time Index values in the Scorecard seem lower than some other studies. This is likely for two reasons: —— By using a data driven reference speed instead of a flat speed for free flow, such as 60 mph, results in lower uncongested speeds in most cases, meaning less congestion is calculated for the same average speeds; and —— INRIX coverage extends throughout entire metropolitan areas including highways and commuting corridors far away from city centers that may contribute less to congestion than roads in the urban core, lowering the index.
•
Studies may have different metropolitan areas, or aggregate some regions such as Washington, D.C. and Baltimore. The Scorecard approach could easily adjust market boundaries to aggregate results differently, but is presently based on the standardized, Census CBSA definition.
•
The Scorecard is focused on mainline lanes of limited access highways; other studies may include ramps, interchanges and arterials.

Acknowledgements and Contact Information Acknowledgements Rick Schuman, INRIX vice president of public sector, is the author of the INRIX National Traffic Scorecard and the driver behind the primary analysis of the metropolitan and bottleneck data. INRIX historically works with data providers, technology partners, experts and our customers to address traffic issues in North America and Europe. Collaborating to create unique and important products is key to INRIX’s success. This Scorecard is no different. INRIX would like to thank several organizations and individuals who have assisted in one way or another in creating the approaches used in the initial 2007 Scorecard, that are also used in this 2008 update. Tim Lomax and Shawn Turner of the Texas Transportation Institute, Rich Margiotta of Cambridge Systematics and Mark Hallenbeck of the University of Washington aided in development of the original Scorecard methodology. Kevin Loftus of INRIX’s partner Clear Channel Total Traffic Network provided local market knowledge and assistance.
Future Updates Leveraging the nation’s most robust historical traffic data warehouse, INRIX is committed to publishing this report on an annual basis. Based on input and feedback, INRIX will continue to improve and expand the report in areas such as additional road coverage (the interstate network, arterials, additional metropolitan areas, etc.) and adding metrics, such as travel reliability and trending analysis. There are many possible extensions and expansions to the information provided in this report. We welcome inquiries from public agencies and transportation data analysts to conduct more in-depth regional or national analyses based upon our traffic data archive and look forward to partnering to tap local knowledge and domain expertise to take full advantage of our data, and to incorporate and correlate with additional data sets (i.e., construction, incidents, weather, etc.). INRIX will also continue to publish Scorecard Special Reports on key topics, similar to The Impact of Fuel Prices on Consumer Behavior and Traffic Congestion released in Fall, 2008.

Acknowledgements and Contact Information Smart Dust Network— The INRIX Smart Dust Network is a breakthrough in traffic technology that dramatically advances the accuracy, coverage and quality of INRIX services. It collects more data about traffic conditions than any solution on the market today, acquiring real-time and historical data from hundreds of public and private sources – including anonymous, real-time GPS probe data from nearly a million commercial fleet, delivery and taxi vehicles; toll tag data from systems such as California’s FasTrak system; and road occupancy and speed measurements from Departments of Transportation around the country. INRIX is the first company in the industry to make use of all these valuable data sources. The INRIX Smart Dust Network also factors in real-time incident data from across around the United States, as well as hundreds of market-specific criteria that affect traffic, such as construction and road closures, sports games and entertainment events, school schedules and weather forecasts. While some traffic solutions rely entirely on road sensors – which are expensive and often error-prone – INRIX’s wide range of data sources enables it to provide high-quality information in cities and states where accurate traffic data was not previously available – such as Miami, Las Vegas, New York, Tampa, San Antonio and Providence, R.I. In fact, recent ground truth testing shows that INRIX technology was able to deliver an 8-15% accuracy advantage over traditional embedded road sensors. Innovative Technologies— INRIX innovations in predictive, historical and real-time traffic technologies and solutions enable our customers to introduce enhanced products and services using accurate time estimation and dynamic route guidance capabilities – all critical for the next generation of navigation solutions. Additionally, INRIX’s innovations in business strategy have further enabled the company to scale through key strategic partnerships, business models, and its focus on the needs of customers.

National Traffic Scorecard
2008 Annual Report
Executive Summary In June 2008, INRIX published the groundbreaking INRIX National Traffic Scorecard (available at http://scorecard. inrix.com). Using data from 2007, the initial Scorecard provided a comprehensive and consistent overview of where and when congestion exists on the major roads in America’s top 100 metropolitan areas. This 2008 Scorecard, available less than 60 days after the end of 2008, summarizes the state of congestion in 2008 across the America and how it changed versus 2007. Like most other aspects of society, 2008 was no ordinary year in terms of traffic or congestion, for several high profile reasons: •
Fuel prices. 2008 brought unprecedented fuel price volatility, with a massive and consistent increase through the first half of 2008 followed by an even greater plunge in prices during the second half of 2008. Overall, average fuel costs in 2008 were up nearly 20% from 2007.
•
Unemployment. Peak hour traffic is largely associated with commuter traffic, people traveling to and from jobs. 2008 saw a steady increase in the nation’s unemployment rate, with every month being higher than the comparable month in 2007.
•
Traffic Volume. The combination of higher fuel prices and a struggling economy yielded a consistent decline in overall traffic volume. Official figures from the Federal Highway Administration (FHWA) show that the first eleven months of 2008 were substantially below 2007 levels, with percentage reductions never before recorded. Overall, FHWA reported a 3% reduction in vehicle miles traveled on the types of roads analyzed in this Scorecard.
Leveraging tens of billions of data points from 2006, 2007 and 2008 collected and archived by the INRIX Smart Dust Network, this Scorecard publishes the most up-to-date information regarding overall congestion and specific bottlenecks on the major roadways of urban America. By analyzing over 30,000 road segments on more than 47,000 miles of the major highways in the nation’s 100 largest metropolitan areas, this report informs the ongoing debate of one of the nation’s most frustrating and intractable issues: urban traffic congestion. How bad is congestion? Where is it worst? How has it changed? What can be done about it? This Scorecard provides the most comprehensive and timely national scale glimpse of the answers to these questions.
National Congestion Results and Trends Overall, the nation’s peak period time Travel Time Index (TTI) for 2008 was 1.09. This means that during peak driving times a random traveler on a random trip on the roads analyzed took 9% extra time, on average, than

Executive Summary if there was no congestion. This represents a decrease in the Travel Time Index of 3.5% from 2007; more than reversing the increase of 1.9% between 2007 and 2006 (see Figure ES-1).

Figure ES-1: National Travel Time Index by Year
When considering the change in congestion – which is the extra amount the Travel Time Index is above 1.00 (a Travel Time Index of 1.00 would define an instance when no congestion existed and a trip was taken entirely in free flow conditions) – the decrease is even more startling: peak hour congestion on the major roads in urban America decreased nearly 30% in 2008 versus 2007. As the details in the Scorecard highlight, other key results include: •
National congestion was lower every hour of every day in 2008 versus 2007 – between 15% and 60% lower depending on the hour and day.
•
Friday from 5 to 6 PM remained America’s most congested hour of the week, although the Travel Time Index fell 23% from 1.26 to 1.20, just ahead of Thursday 5 to 6 PM, which had a TTI of 1.19 in 2008.
•
Wednesday saw the biggest drop in congestion, with a 31% overall decrease in peak periods.
•
Each weekday morning, peak hour congestion dropped much more than its corresponding evening peak hour congestion (See figure ES-2).
•
National congestion levels were essentially the same when comparing the first and second halves of 2008, thus it seems that higher fuel prices in early 2008 and the slower economy later in the year netted the same drop in overall congestion.

Figure ES-2: % Drop in National Congestion by Day (2008 vs. 2007)
•
Congestion in off peak hours (outside of the AM and PM weekday commuting times) decreased by more than 36%, substantially outpacing the significant drop in peak hour congestion.
As expected, the health of the economy and higher average fuel costs led to decreased congestion – but the scale of the decrease, roughly 30%, is startling.
Metropolitan Comparisons and Trends
A 3% drop in vehicle miles traveled resulted in a 30% drop in peak period congestion in 2008.
While no region of the country was spared volatile fuel prices and some amount of economic stress, some regions clearly have had a better or worse relative impact. Couple these differences with variations in overall highway construction and maintenance activity – a key contributor to recurring regional congestion as highlighted in later sections – and the reduction in overall congestion varied widely by metropolitan area. Figure ES-3 highlights the nation’s top 10 regions in terms of overall congestion, Travel Time Index (which normalizes the congestion data by road miles analyzed in each region, giving the fairest consumer-oriented view of congestion in a region), the biggest drops in Travel Time Index between 2007 and 2008, and the most congested “worst hour” rankings.

In almost all cases, when regions moved up a list, it was due to less congestion reduction than its peer regions in that category. For example, despite a 20% drop in congestion, the Minneapolis-St. Paul region moved from 13th to 10th in total congestion, passing Atlanta, Miami, and Philadelphia.
•
Los Angeles moved ahead of Honolulu with the highest metropolitan Travel Time Index. Honolulu’s 34% drop in congestion lowered its Travel Time Index from 1.45 to 1.31, where Los Angeles’ 23% drop lowered its TTI from 1.44 to 1.33

Executive Summary Bottlenecks Nearly 31,000 individual road segments were analyzed to determine the extent and amount of average congestion each had in 2008. More than 6000 segments registered at least one hour of the week when one can expect to travel at less than half the free flow or uncongested speed. As expected based on the overall congestion data, the number and intensity of bottlenecks were down considerably from 2007. Overall 28% fewer segments had at least one hour of congestion in 2008. Figure ES-4 details the drop for each threshold.

The nation’s worst bottleneck remained the same, a westbound stretch of the Cross Bronx Expressway/I-95 leading up to and including the Bronx River Parkway exit 4B interchange. As in 2007, it was congested an astounding 94 hours of the week, but the average speed while congested rose in 2008 to 11.2 MPH from 9.8 MPH.
ES-5
National Traffic Scorecard
2008 Annual Report
Executive Summary One third of the top 100 bottlenecks in 2007 were not in the top 100 in 2008. Five of the road segments that dropped out of the top 100 fell outside of the Top 1000 – four of these were on the Dan Ryan Expressway in Chicago, which was part of a multi-year construction project that ended in 2007. As in 2007, more than half of the nation’s top 1000 bottleneck segments (see Figure ES-5) were in the New York, Los Angeles and Chicago areas. Roughly one fourth of the nation’s top 1000 bottlenecks in 2007 fell out of the top 1000 in 2008. Again, much of the volatility appears tied to the beginning or ending of long-term construction or maintenance projects. Overall, the top 1000 bottlenecks in 2008 were congested an average of 26 hours each week (versus 31 hours in 2007), with an average speed while congested of 18 MPH (versus 16 MPH in 2007).

Specific noteworthy bottleneck work zones include: •
The top 2007 bottleneck to have “0 hours” of congestion in 2008: —— I-35E Southbound at I-694 in Minneapolis-St. Paul (63rd in 2007)
•

•
The top 2008 bottleneck not ranked in 2007: —— Ronald Reagan Freeway/SR 118 Eastbound at Stearns Drive in Ventura County, California (ranked 154th in 2008)
ES-6
National Traffic Scorecard
2008 Annual Report
Executive Summary Conclusions With a new presidential administration, the just-passed stimulus package, and the upcoming expiration of SAFETEA-LU, this is an important year for transportation issues. The Scorecard has generated some relevant findings to assist in both national and regional debates, including: •
Volume changes have much bigger impacts under congested conditions. FHWA data shows that in 2008, traffic on “urban interstates” was down 3% nationwide compared to 2007. This has translated to a nearly 30% reduction in peak hour congestion and an even larger 36% drop in off-peak congestion. This illustrates multiple issues: —— Demand management can have sizeable impact on congestion, even if total volume changes are modest. Massive increases in fuel prices had effects similar to policy initiatives under consideration such as variable pricing, managed lane strategies and better travel information. When a road network is at capacity, adding or subtracting even a single vehicle has disproportionate effects for the network. This phenomenon has been well known for a long time, but this data illustrates it in real-world terms on a nationwide basis. —— While the drop in congestion is welcomed in general, the primary root causes – high fuel costs and lagging economic activity – are not. Ideally, the nation’s economy will turn around in short order and fuel prices will remain moderate. If so, we can expect congestion to largely snap back to levels comparable to 2007 levels or worse. While we all should cheer the reduction in congestion in 2008, we should be under no illusion that this is permanent. We must still continue to focus energies on policies and methods to tackle congestion. When the economy is growing again, congestion will likely move to the front and center again as the nation’s primary surface transportation problem.
•
The linkage between work zones and bottlenecks. The significant percentage of bottlenecks that appear to be related to work zones underscores the need to focus on managing work zones in ways that mitigate congestion. With the upcoming stimulus spending, the amount of work zones is likely to grow to numbers never before seen. Further, there is strong desire to move as quickly as possible in getting highway projects underway. Proper work zone planning will be essential if we are to keep the nation’s highways from becoming a parking lot.

National Traffic Scorecard
2008 Annual Report
Introduction In June 2008, INRIX published the groundbreaking INRIX National Traffic Scorecard.1 Using data from 2007, the initial Scorecard provided a comprehensive and consistent overview of where and when congestion existed on the major roads in America’s top 100 metropolitan areas. This 2008 Annual Report of the Scorecard, available less than 60 days after the end of 2008, summarizes the state of congestion in 2008 across the U.S.
2008: A Blip or a Trend? Historically, traffic volumes and congestion, like the size of the economy and the population have tended to consistently rise year after year. While the occasional recession or fuel price spike may halt the upward march of traffic, it has almost always been only a small and temporary pause. 2008 was different. As one might expect, in terms of traffic and congestion, 2008 was no ordinary year, on several fronts: Fuel prices. 2008 brought unprecedented fuel price

So, 2008 wasn’t just another year where things generally get somewhat worse in terms of congestion. Having the nation’s most extensive traffic data repository, with more than three times the data points to leverage in 2008 versus 2007, has enabled INRIX to provide this unique, timely and important report summarizing how these unprecedented circumstances affected traffic congestion in 2008.
INRIX’s Unique and Timely Traffic Data Archive In 2006, INRIX introduced the Smart Dust Network, the first truly national traffic data collection network. The Scorecard has established an equally revolutionary approach to measuring the nation’s traffic congestion problem. Leveraging tens of billions of data points from 2006, 2007 and 2008 collected and archived by the Smart Dust Network, this report publishes the most up-to-date information regarding overall congestion and specific bottlenecks on the major roadways of urban America. By analyzing over 30,000 road segments on more than 47,000 miles of the major highways in the nation’s 100 largest metropolitan areas, this report informs the ongoing debate of one of the nation’s most frustrating and intractable issues: urban traffic congestion. How bad is congestion? Where is it worst? How has it changed? What can be done about it? This Scorecard provides the most comprehensive and timely national scale glimpse of the answers to these questions.

National Traffic Scorecard
2008 Annual Report
Methodology The INRIX National Traffic Scorecard draws from several existing approaches to calculating traffic congestion and leverages new methods made possible by INRIX’s proprietary data. This section provides background on the raw data and the processes used.
Source Data The raw data comes from the historical traffic data warehouse of the INRIX Smart Dust Network. Since 2006, INRIX has acquired tens of billions of discrete “GPS-enabled probe vehicle” reports from vehicles traveling the nation’s roads – including taxis, airport shuttles, service delivery vans, long haul trucks, and consumer vehicles. Each data report from these GPS-equipped vehicles includes the speed, location and heading of a particular vehicle at a reported date and time. INRIX has developed efficient methods for interpreting probe vehicle reports that are provided in real-time to establish a current estimate of travel patterns in all major cities in the United States. These same methods can aggregate data over periods of time (annually in this report) to provide reliable information on speeds and congestion levels for segments of roads. With the nation’s largest probe vehicle network, INRIX has the ability to generate the most comprehensive congestion analysis to date, covering the nation’s largest 100 metropolitan areas.
Metropolitan Area The US Census Bureau definition of Core Based Statistical Areas (CBSA)3 is used to define metropolitan areas. This report uses the latest 2007 census estimates4 to identify the top 100 areas.
Roads/Segments Analyzed This report focuses on the major limited access roads in the top metropolitan areas in the United States. In all of its products, INRIX utilizes an industry convention known as “TMC location codes” developed and maintained by the nation’s leading electronic map database vendors to uniquely define road segments. The typical road segment is the interchange and the portion of linear road leading up to the interchange across all lanes in a single direction of travel. The length of a segment will depend upon the length of the distance between interchanges. For this report, over 47,000 road miles in nearly 31,000 discrete road segments have been analyzed (see Figure 4).

Analysis Time Period The focus of this report is the calendar year 2008. In some cases, calendar year 2006 and 2007 data is utilized to enable year over year comparisons.
Road Segment Data There are two key building blocks for the different analyses included in this report: •
Reference speed (RS): For each road segment, all probe vehicle reports obtained in overnight hours (where congestion is usually unlikely) in 2008 are analyzed. The 85th percentile of those data points is identified as the “reference speed” for that particular road segment. This is typically the speed of “free flow” traffic if and when no congestion exists. Each segment has a single reference speed.
•
Hourly average speed (HS): All probe vehicle reports for each road segment are grouped by hour of day, day of week (e.g. Monday from 3 to 4pm) and an “average speed” for each time slot is established for each road segment. Thus, each segment has 168 corresponding hourly average speed values – representing 24 hours of each day muliplied by the seven days in a week.

2008 Annual Report
Methodology Overall Congestion Metrics – Regional and National To assess congestion for a CBSA, INRIX utilizes several concepts that have been used in similar studies. •
Travel Time Index (TTI): TTI is the ratio of peak period travel time to free flow travel time. The TTI expresses the average amount of extra time it takes to travel in the peak relative to free-flow travel. A TTI of 1.3, for example, indicates a 20-minute free-flow trip will take 26 minutes during the peak travel time periods, a 6-minute (30 percent) travel time penalty.5 For each road segment, a TTI is calculated for each hour of the week, using the formula TTI = RS/HS.
•
“Peak Hour” Congestion: To assess and compare congestion levels year to year and between CBSAs, only “peak hours” are analyzed. Consistent with similar studies, peak hours are defined as the hours from 6 to 10 AM and 3 to 7 PM, Monday through Friday – 40 of the 168 hours of a week.
For each Metropolitan Area, an overall level of congestion is determined for each of the 40 peak hours by determining the extent and amount of average congestion on the analyzed road network. This is easy to compute once TTI’s are calculated for each segment:
STEP 1: For each of the 40 peak hours, all road segments analyzed in the CBSA are checked. Each segment where the TTI > 1 is contributing congestion, and it is analyzed further. STEP 2: For each segment contributing congestion, the amount the TTI is greater than 1 is multiplied by the
length of the segment, resulting in a congestion factor. STEP 3: For a given hour, the overall metropolitan congestion factor is the sum of the congestion factors
calculated in STEP 2. STEP 4: To establish the Metropolitan Travel Time Index for a given hour, the metropolitan congestion factor
from STEP 3 is divided by the number of road miles analyzed.
STEP 5: A peak period Metropolitan Travel Time Index is determined by averaging the hourly Metropolitan Travel Time Indices from STEP 4.
New for this 2008 Annual Update, monthly Travel Time Index values have been calculated for each CBSA and nationally as well and are included in subsequent sections.

2008 Annual Report
Methodology Bottlenecks With the unique ability to examine in detail nearly 31,000 urban highway road segments, INRIX identifies the specific locations in each metropolitan area – and can compare locations across the country – that are consistently congested. These are “bottlenecks.” 6 Congestion – and how to measure it – can be in the eye of the beholder. Is congestion defined as how bad a road segment is at its worst or is it how often the segment gets “congested” (and what is the threshold for “congestion” anyways – tapping the brakes, stop and go conditions, etc.)? INRIX has developed a method that combines both the amount of time a road segment is congested with the intensity of congestion during those periods. The process used to analyze each of the nearly 31,000 road segments is as follows: •
The same RS and HS values are utilized as in the overall congestion by metropolitan area portion of the study;
•
All 168 hours of the week are considered, not just the 40 “peak hours.” As will be evident in the data, severe bottlenecks aren’t just limited to peak hours;
•
For each hour of the week that the average speed is less than 50% of the reference speed (RS), the hour is considered “congested;”
•
For all “congested” hours, the average intensity of the congestion is determined by establishing an average travel time ratio;
•
The total bottleneck factor equals the number of hours of congested by the average travel time ratio.
•
Each road segment’s bottleneck factor can be compared with others in a metropolitan area and against all bottlenecks nationally. It can also be compared year-to-year, as we have in this Scorecard.
From the Federal Highway Administration: Traffic Bottleneck: (Simple definition) A localized constriction of traffic flow. (Expanded definition) A localized section of highway that experiences reduced speeds and inherent delays due to a recurring operational influence or a nonrecurring impacting event.

National Congestion Results and Trends The methodology used to measure overall congestion and to establish the metropolitan Travel Time Index for each of the weekly 40 drive time hours enables the calculation of overall national congestion metrics, by hour, by morning and evening drive time, by day and overall. New for the 2008 Annual Update is the inclusion of monthly data as well.
Overall Travel Time Index and Congestion Overall, the nation’s peak period time Travel Time Index for 2008 was 1.09. This means that during peak driving times7 a random traveler on a random trip on the roads analyzed took on average 9% extra time than if there was no congestion. This represents a 3.5% decrease in the Travel Time Index from 2007 – more than reversing the increase of 1.9% between 2007 and 2006 (see Figure 5).

Figure 5: National Travel Time Index by Year
When considering the change in congestion – which is the extra amount the Travel Time Index is above 1.00 (a Travel Time Index of 1.00 would define an instance when no congestion existed and a trip was taken entirely in free flow conditions) – the decrease is even more startling: peak hour congestion on the major roads in urban America decreased nearly 30% in 2008 versus 2007. So, if the average amount of delay time per traveler in 2007 was 44 hours8, the approximate reduction in delay per traveler in 2008 was 13 hours. This means the average traveler “saved” 13 hours in time off the roads in 2008 versus 2007. The data also reveal that off peak hours – the 128 hours of the week not analyzed in the peak driving hours – saw a larger percentage drop in congestion than the peak hours, down roughly 36% versus 2007.
Peak period drive time hours are 6 – 10 AM and 3 – 7 PM, Monday through Friday. See Texas Transportation Institute’s 2007 Urban Mobility Report, where the average annual delay per travel in 2005 in the 85 “large areas” studied was 44 hours (http://mobility.tamu.edu/ums/).

National Congestion Results and Trends National Travel Time Index by Hour and Day of Week A national perspective shows the Travel Time Index/overall congestion for every hour and day of the week was well below its level in 2007. Figure 6 shows the 2008 National Travel Time Index by the hour and day of the week (note: “5 PM” in the figures refers to the 5-6 PM hour, etc.). Figures 7-13 compare National TTI for each day and hour between 2007 and 2008. Noteworthy findings: —— Friday from 5 to 6 PM remained America’s most congested hour of the week, although the Travel Time Index fell 23% from 1.26 to 1.20, just ahead of Thursday 5 to 6 PM, which had a TTI of 1.19 in 2008. —— Wednesday saw the biggest drop in congestion, with a 31% overall decrease in peak hours. —— Each weekday morning, peak hour congestion dropped much more than its corresponding evening peak hour congestion (See figure 14).

It should be noted that traffic volumes have historically varied significantly from month-to-month over the course of a calendar year. It is anticipated that monthly TTI – both nationally and in each region – will exhibit similar characteristics, meaning that over time, it will be more meaningful to compare the same month from year to year, than the current month to the last month. In 2008 however, given the dramatic change in circumstances from the first half to the second half of the year, it is meaningful to compare the average Travel Time Index from the first 6 months to the second 6 months of 2008. Interestingly, likely for very different reasons, the Travel Time Index for each half of 2008 is virtually identical: 1.093 for 1H 2008 versus 1.095 for 2H 2008.

National Traffic Scorecard
2008 Annual Report
Metropolitan Rankings •
In almost all cases, when a region moved up a list, it was due to less congestion reduction than its peer regions in that category. For example, despite a 20% drop in congestion, the Minneapolis-St. Paul region moved from 13th to 10th in total congestion, passing Atlanta, Miami, and Philadelphia.
•
99 of the 100 regions saw congestion levels decrease. Baton Rouge, LA, with a 6% increase in overall congestion, was the only region with an increase from 2007, shooting it up the metropolitan rankings from 47th to 33rd in overall congestion.
•
Los Angeles moved ahead of Honolulu with the highest metropolitan Travel Time Index. Honolulu’s 34% drop in congestion lowered its Travel Time Index from 1.45 to 1.31, while Los Angeles’ 23% drop lowered its TTI from 1.44 to 1.33.
•
The largest drops in congestion by percentage are dominated by metropolitan areas of less than 1 million people. Many had modest congestion in 2007 when compared to larger regions, so modest drops in congestion resulted in larger percentage drops than the larger areas.
•
The largest drops in congestion and rankings of the “big cities” included the Atlanta, Miami, Detroit, San Diego and the “Inland Empire” (Riverside-San Bernardino-Ontario) region of California, all having drops in peak hour congestion of at least 36% from 2007.
Overall, while congestion clearly dropped across the country, this drop was not uniform across all regions, and depending upon where one lives or when they travel, congestion – though likely better than in 2007 – was still substantial.

National Traffic Scorecard
2008 Annual Report
Bottlenecks Nearly 31,000 individual road segments were analyzed to determine the extent and amount of average congestion each segment had in 2008. More than 6000 segments contained at least one hour of the week where one can expect to travel at less than half the uncongested speed. Based on the overall congestion data, the number and intensity of bottlenecks was down considerably from 2007. Overall 28% fewer segments had at least one hour of congestion in 2008. Figure 17 details the drop for each threshold. Also, 25 metropolitan areas had no significant bottlenecks (defined as congested four or more hours per week), up from 17 areas in 2007.

National Traffic Scorecard
2008 Annual Report
Bottlenecks in 2007, it was congested an astounding 94 hours of the week, but the average speed while congested rose in 2008 to 11.2 MPH from 9.8 MPH. Eight of the 10 worst bottlenecks in 2007 remained in the top 10 for 2008, with the other two moving to 11th and 16th places. They were replaced in the top 10 by 2007’s 12th and 16th worst bottlenecks. Beyond the top ten, the “mobility” of the bottlenecks up and down the list was significant. Thirty-three of the top 100 bottlenecks in 2007 were not in the top 100 in 2008. Five of those segments that dropped out of the top 100 fell outside of the Top 1000. Quick review suggests a strong correlation between work zone activity and bottlenecks. As an example, a single bottleneck in the 2007 top 100, I-35E Southbound at I-694 in MinneapolisSt. Paul which ranked 63rd worst in 2007, had no hours in 2008 where the average speed was half or less of free flow speed. This area was a work zone associated with a multi-year “Unweave the Weave” project10 that has significantly improved the I-35E/ I-694 Interchange. Similarly, the other four segments that dropped from the top 100 in 2007 to outside the top 1000 in 2008 were segments of the Dan Ryan Expressway in Chicago that was part of a multi-year construction project that ended in 200711. Figure 18 summarizes the collective improvement of congestion in the nation’s worst bottlenecks. On average, these bottlenecks saw 3 less hours of congestion and saw speeds increase nearly 2 MPH. When factoring in fewer delays in these bottlenecks for less periods of the week, the nation’s 100 worst were about 16% less congested in 2008 than in 2007.

2008 Annual Report
Bottlenecks In 2008, 252 of the nation’s top 1000 bottlenecks in 2007 fell from the top 1000. Again, much of the volatility appears tied to the beginning or ending of construction or maintenance projects. The highest ranking addition to the 2008 list of bottlenecks that did not have even one average hour of “congested” conditions in 2007 was Ronald Reagan Freeway/SR 118 Eastbound at Stearns Drive in Ventura County, California. Ranked 154th overall in 2008, this bottleneck was created as part of a widening project in the area that began in March 2008 and is expected to be completed in mid-2009.12 Two other adjacent road segments also moved from no recurring congestion in 2007 to the top 1000 bottlenecks in 2008. Overall, as Figure 21 highlights, the top 1000 bottlenecks in 2008 were congested an average of more than 5 hours less each week, with an average speed increase of 1.4 MPH than those in 2007, leading to a roughly 23% drop in congestion impacts of the top 1000 bottlenecks.

-4.4% -16.7% 8.2% -22.8%
Figure 21: Average Conditions of Nation’s 1000 Worst Bottlenecks
When examining the bottlenecks on a national basis, several conclusions can be drawn: •
Bottlenecks aren’t just a mega city issue. While a majority of bottlenecks are in Los Angeles, New York and Chicago, 41 of the 100 areas had at least one bottleneck in the top 1000 in 2008.
•
While down from 2007, more than 1000 road segments are congested, on average, at least 10 hours a week. Add in an accident, bad weather or a special event and these locations, though likely better on average than in 2007, can still gridlock quickly. Even with the “perfect storm” of conditions in 2008 that generally reduced congestion, there is still no margin for error on a large portion of our major highway network.
•
Construction, while helping in the long run, can create long-term temporary bottlenecks. As the “stimulus package” signed into law in mid-February 2009 jump starts “shovel-ready” projects nationwide, planners of those projects should heed these results as evidence that careful maintenance of traffic planning should not be short-changed, as what appear as temporary bottlenecks from a project perspective can lead to recurring congestion for weeks, months or even years.

2008 Annual Report
Bottlenecks •
Several of the individual road segments identified as bottlenecks are connected to other segments also identified as bottlenecks – basically corridor bottlenecks. While these may be associated with an upstream interchange or geometric configuration issue, the length of these bottlenecks can be long and troubling for drivers.
•
Moderate congestion can and does disappear. Perhaps since the birth of the interstate system, the national psyche has been conditioned to accept that congestion is bad, getting worse with little or no chance to stop it. More than 2000 road segments that had at least one hour of congestion in 2007 had no identified recurring congestion in 2008, clearly demonstrating that the march towards gridlock can be reversed. While the causes of the decline in 2008 – lower demand due to fuel prices and lower economic activity – aren’t the most desired ways to achieve these reductions, it does show that it is possible reverse the trend. Policies that can influence demand at the right places and times may be able to show the same benefits.

National Traffic Scorecard
2008 Annual Report
Scorecard Relationship with Other Studies As one would expect for an issue as relevant to our daily lives and economic system as traffic congestion, there are many recently published studies on the issue. This Scorecard expands upon and complements these reports. The following list is but a few of the notable recent reports: —— 2007 Annual Urban Mobility Report (Texas Transportation Institute): http://mobility.tamu.edu/ums/ —— Unclogging America’s Arteries: Effective Relief for Highway Bottlenecks 1999-2004 (American Highway Users Alliance): http://www.highways.org/pdfs/bottleneck2004.pdf —— Building Roads to Reduce Traffic Congestion in America’s Cities: How Much and at What Cost? (Reason Foundation): http://www.reason.org/ps346/state_by_state_congestion.pdf —— Freight Performance Measurement: Travel Time in Freight-Significant Corridors (Federal Highway Administration): http://ops.fhwa.dot.gov/freight/freight_analysis/perform_meas/fpmtraveltime/index.htm —— America’s Most Congested Cities (Forbes Life Magazine): http://www.forbes.com/2008/04/10/congestedcommute-cities-forbeslife-cx_mw_0410realestate.html —— Where the Commuting Nightmares Are (bizjournals): http://www.bizjournals.com/edit_special/56.html —— The Road…Less Traveled: An Analysis of Vehicle Miles Traveled Trends in the U.S.: http://www.brookings. edu/reports/2008/~/media/Files/rc/reports/2008/1216_transportation_tomer_puentes/vehicle_miles_ traveled_report.pdf While the Scorecard shares some common elements with these reports, it also has several unique features. •
Common elements —— The Scorecard adopts the common convention of peak period drive time hours of 6 – 10 AM and 3 – 7 PM, Monday through Friday. —— The Travel Time Index concept is now a standard metric to measure conditions relative to uncongested, free flow situations.
•
Unique features —— This report is based on data, technology and processes that have been designed to optimize very quick turnaround times between the end of the data collection period and the publishing of the Scorecard. Many of the reports utilize data that is many months or years old when published. —— The Scorecard is completely based upon real data – tens of billions of data points from real consumer and commercial vehicles traveling on real road segments. It is not limited by sensor coverage nor is it an interpolation of data.
26
National Traffic Scorecard
2008 Annual Report
Scorecard Relationship with Other Studies —— This is the first analysis to go to the detailed road segment level nationwide; it is also the first to look in depth by hour and day nationwide. Further, this report offers a unique opportunity to see trending by time, region or specific road segment. Given the myriad of ways to calculate congestion and the wide range of raw data that is utilized, it is natural that different reports can have different results, rankings and indexes. When comparing differences between the Scorecard and other reports, it could be due to one or more of the following reasons: •
Many of the reports weight results by traffic volume and/or factor in the number of lanes on roadways; the Scorecard does not.
•
Travel Time Index calculations are from a road user perspective based on complete random trips, not weighted by volumes, lane miles, or origin/destination weighting.
•
Travel Time Index values in the Scorecard seem lower than some other studies. This is likely for two reasons: —— By using a data driven reference speed instead of a flat speed for free flow, such as 60 mph, results in lower uncongested speeds in most cases, meaning less congestion is calculated for the same average speeds; and —— INRIX coverage extends throughout entire metropolitan areas including highways and commuting corridors far away from city centers that may contribute less to congestion than roads in the urban core, lowering the index.
•
Studies may have different metropolitan areas, or aggregate some regions such as Washington, D.C. and Baltimore. The Scorecard approach could easily adjust market boundaries to aggregate results differently, but is presently based on the standardized, Census CBSA definition.
•
The Scorecard is focused on mainline lanes of limited access highways; other studies may include ramps, interchanges and arterials.

Acknowledgements and Contact Information Acknowledgements Rick Schuman, INRIX vice president of public sector, is the author of the INRIX National Traffic Scorecard and the driver behind the primary analysis of the metropolitan and bottleneck data. INRIX historically works with data providers, technology partners, experts and our customers to address traffic issues in North America and Europe. Collaborating to create unique and important products is key to INRIX’s success. This Scorecard is no different. INRIX would like to thank several organizations and individuals who have assisted in one way or another in creating the approaches used in the initial 2007 Scorecard, that are also used in this 2008 update. Tim Lomax and Shawn Turner of the Texas Transportation Institute, Rich Margiotta of Cambridge Systematics and Mark Hallenbeck of the University of Washington aided in development of the original Scorecard methodology. Kevin Loftus of INRIX’s partner Clear Channel Total Traffic Network provided local market knowledge and assistance.
Future Updates Leveraging the nation’s most robust historical traffic data warehouse, INRIX is committed to publishing this report on an annual basis. Based on input and feedback, INRIX will continue to improve and expand the report in areas such as additional road coverage (the interstate network, arterials, additional metropolitan areas, etc.) and adding metrics, such as travel reliability and trending analysis. There are many possible extensions and expansions to the information provided in this report. We welcome inquiries from public agencies and transportation data analysts to conduct more in-depth regional or national analyses based upon our traffic data archive and look forward to partnering to tap local knowledge and domain expertise to take full advantage of our data, and to incorporate and correlate with additional data sets (i.e., construction, incidents, weather, etc.). INRIX will also continue to publish Scorecard Special Reports on key topics, similar to The Impact of Fuel Prices on Consumer Behavior and Traffic Congestion released in Fall, 2008.

2008 Annual Report
Acknowledgements and Contact Information INRIX is different from other traffic information providers, with the broadest coverage in the most locations: 145 metropolitan areas and more than 120,000 miles of roads in the U.S., Canada, and Europe. With its unique fusion of traditional sensors and nearly a million GPS-enabled vehicles, INRIX ensures the highest accuracy of its traffic data. And, with the launch of INRIX Connected Services in mid-2008, INRIX is now aggregating and delivering new in-car solutions featuring third generation routing and other innovative dynamic content such as safety and weather alerts, fuel prices, news/stocks/weather/sports, business and category search, movie times, and travel information. Highest Quality — INRIX has consistently introduced breakthrough solutions including predictive traffic technologies, Total Fusion and Connected Services. In a further industry effort to demystify the quality analysis of traffic information, INRIX also recently published Benchmarking Traffic Data Quality: Best Practices for Analyzing the Quality of Traffic Information (see Figure 23), which is available at www.inrix. com. This 60-page technical primer on traffic data quality provides a benchmark from which to evaluate the many components that make up the quality of traffic information. With respect to data integrity and quality, INRIX leads the industry with its sharp focus on quality using intelligent data fusion, advanced analytics and extensive quality processes. Broadest Coverage—

INRIX provides coverage in more markets and more roadways within markets than any other company. Leveraging its unique Smart Dust Network, INRIX provides accurate real-time, historical and traffic fusion speed information for major freeways, highways and arterials in every major metropolitan area in the U.S. and Canada. Additionally, INRIX recently introduced real-time flow coverage for roadways throughout the entire U.K. and the Netherlands, and real-time incident coverage for 16 countries in Europe.

2008 Annual Report
Acknowledgements and Contact Information Smart Dust Network— The INRIX Smart Dust Network is a breakthrough in traffic technology that dramatically advances the accuracy, coverage and quality of INRIX services. It collects more data about traffic conditions than any solution on the market today, acquiring real-time and historical data from hundreds of public and private sources – including anonymous, real-time GPS probe data from nearly a million commercial fleet, delivery and taxi vehicles; toll tag data from systems such as California’s FasTrak system; and road occupancy and speed measurements from Departments of Transportation around the country. INRIX is the first company in the industry to make use of all these valuable data sources. The INRIX Smart Dust Network also factors in real-time incident data from across around the United States, as well as hundreds of market-specific criteria that affect traffic, such as construction and road closures, sports games and entertainment events, school schedules and weather forecasts. While some traffic solutions rely entirely on road sensors – which are expensive and often error-prone – INRIX’s wide range of data sources enables it to provide high-quality information in cities and states where accurate traffic data was not previously available – such as Miami, Las Vegas, New York, Tampa, San Antonio and Providence, R.I. In fact, recent ground truth testing shows that INRIX technology was able to deliver an 8-15% accuracy advantage over traditional embedded road sensors. Innovative Technologies— INRIX innovations in predictive, historical and real-time traffic technologies and solutions enable our customers to introduce enhanced products and services using accurate time estimation and dynamic route guidance capabilities – all critical for the next generation of navigation solutions. Additionally, INRIX’s innovations in business strategy have further enabled the company to scale through key strategic partnerships, business models, and its focus on the needs of customers. INRIX Connected Services— The INRIX Connected Services platform offers an unparalleled suite of content services providing navigation OEMs and location-based service application developers with private label, go-tomarket solutions for in-vehicle, personal navigation device (PND), wireless phone and other connected devices. The INRIX Connected Services platform encompasses the world’s first ‘third generation’ routing engine, dynamic traffic data covering 800,000 miles of roadways in North America, additional location-relevant content, and a developer zone designed to greatly simplify creation of location-based service applications.
