Rapid Bus Transit As A Substitute For Light Rail Transit

Bus Rapid Transit as a Substitute for Light Rail Transit A Tale of Two Cities KENNETH G. SISLAK Wilbur Smith Associates

ABSTRACT There is growing awareness that continued development and expansion of high-quality public transportation service is an essential ingredient in modifying mode choice behavior in the United States. In the past 20 years, 12 new start light rail transit (LRT) lines have been constructed in North America as part of a determined effort to change travel patterns in growing cities. However, the cost-effectiveness of constructing expensive new start LRT lines is being questioned by local officials in many smaller cities now engaged in studying the feasibility of such investments. The costs of constructing LRT have spiraled upward, whereas estimated levels of future transit system ridership in smaller cities are relatively low compared to larger cities. Can public transportation services in smaller cities be dramatically improved without the extraordinary capital expenditures required of LRT system construction? Bus rapid transit (BRT) may be a rational and cost-effective way to implement significant transit improvements in smaller cities, and it may cost 40 to 70 percent less than current LRT construction estimates. These cost savings often can be achieved without sacrificing service quality and potential ridership. The service characteristics and attributes of BRT are also often similar to LRT, with the notable exception of the vehicles and supporting infrastructure. This research explores the rationale for building BRT in two different cities: Cleveland, Ohio, and Nashville, Tennessee. The research will compare and contrast the costs, benefits, and cost-effectiveness of the rail and bus alternatives proposed for the travel corridors in these two cities. he resurgent interest in bus rapid transit (BRT) within the United States is a direct outgrowth of the limited ability of the Federal Transit Administration (FTA) to fund every New Start rail project that is now being conceived, planned, or designed. The inadequate level of funding for New Start rail projects will continue to be a political reality until the U.S. Congress changes the way transportation projects are funded. From the FTA perspective, BRT is a step toward developing improved public transportation systems that have the service delivery characteristics and appeal of a rail transit line at a fraction of the capital cost. This would spread limited federal resources to more cities. The direct federal investment in improved transit services in more American cities would become a major catalyst in the process of changing mode choice behaviors and arresting urban core disinvestment throughout the country. This stewardship of federal investment is even more prudent when many feasibility studies indicate that required ridership thresholds on proposed New Start rail lines in many cities won’t be achieved until sometime in the

future. Some planned light rail transit (LRT) systems have average daily ridership estimates in the 15,000 to 20,000 range. There are many bus lines in the United States that carry as many or more riders on a daily basis, including the Euclid Corridor line in Cleveland. This research explores the rationale of building BRT in two different cities: Cleveland, Ohio, and Nashville, Tennessee. Each city has unique travel demand characteristics and population growth trends. In Cleveland, the BRT system was selected as the locally preferred alternative for the Euclid Corridor upon completion of the Dual Hub Corridor Transitional Analysis (1) in 1995. In Nashville, BRT is being considered as a lower-cost alternative to an urban core LRT line. The BRT in Cleveland is a substitute for LRT, while the BRT in Nashville is viewed as a precursor to LRT. The reasons for this are directly related to the population and employment growth characteristics of the two cities. Cleveland is an older, northern city with relatively flat population and employment growth. Transit ridership is not expected to increase significantly over the next 20 years. Nashville, on the other hand, is experiencing tremendous growth in both employment and population growth. ATTRIBUTES OF BUS RAPID TRANSIT Bus systems are ubiquitous, versatile, and flexible. They are comparatively inexpensive to implement. However, bus systems are not overly appealing to people who value comfort, convenience, and speed. Therefore, the underlying concept of BRT is simple: duplicate the reliability, level of service, comfort, and appeal of a modern LRT line while achieving the flexibility and cost-effectiveness inherent in bus systems. BRT services should include the following attributes: • • • • • • • •

Exclusive bus lanes, bus streets, and busways Bus signal priority or preemption Reliability Traffic management improvements Improved fare collection and boarding/alighting patterns Appealing bus designs and seating arrangements Integration of transit station development with adjacent land-use policy Improved facilities and passenger amenities such as stations and enhanced stops

These attributes appeal to people who place a high emphasis on status, convenience, comfort, and speed. Every BRT design feature must address these needs. In other words, the attributes of BRT must appeal to people who now choose to drive an automobile and must be at least equal to LRT. BRT systems have been successfully deployed throughout the world with varying degrees of success. The most notable BRT systems in the United States are in Houston, Texas; Los Angeles, California (El Monte Freeway); Miami, Florida; Pittsburgh, Pennsylvania; Orlando, Florida (LYMMO); San Francisco, California (Highway 101); and Washington, DC (Shirley Highway). BRT systems under development in the United States include Hartford, Connecticut; Oakland, California; Cleveland, Ohio; Eugene, Oregon; Charlotte, North Carolina; and several other cities with bus transit priority features such as the High Street Corridor in Columbus, Ohio. In other countries, BRT is

growing in importance as well. Some of the more diverse cities that have developed BRT systems are Adelaide, Australia; Curitiba and Sao Paolo, Brazil; Ottawa, Canada; Quito, Ecuador; Caen, Lyon, Nancy, and Paris, France; and Essen, Germany. The most notable and famous is Curitiba. The principles of BRT are highly developed and articulated in the Curitiba example. However, urban design features of the BRT in Curitiba are decidedly different from those that people in the United States have come to expect from high-quality LRT systems. The buses in Curitiba are not air-conditioned, for example. The urban transit system in Paris is developing a system of high-quality BRT services on suburban boulevards, with exclusive lanes to speed the operation of transit service in suburb-tosuburb travel corridors. These BRT lines are intended to be replaced by LRT as passenger traffic on the lines increases. New guided bus technology and dual-mode hybrid electric buses that resemble light rail vehicles are emerging as guided light transit (GLT) in France and Germany. To appeal to status-conscious Americans, Cleveland and Nashville contemplate BRT systems as utilizing exclusive busways on an urban arterial street, with transitpriority signaling. The technology recommended for both systems is low-floor, articulated electric trolleybuses (ETBs). The design of each BRT system is intended to replicate many of the desired features of LRT including stations, traveler information systems, and other attractive urban design features such as art-in-transit. CLEVELAND EUCLID CORRIDOR BRT The Greater Cleveland Regional Transit Authority (RTA) and the city of Cleveland are jointly developing a major transportation infrastructure investment in the Euclid Avenue travel corridor between Public Square in downtown Cleveland and University Circle. This is a distance of approximately 4.3 mi (6.92 km). The project consists of several transportation system management (TSM) elements recommended in the Dual Hub Corridor Transitional Analysis (1). The TSM alternative was adopted by the Northeast Ohio Areawide Coordinating Agency as the region’s locally preferred investment strategy for transportation improvements in the corridor. These TSM improvements center on establishing priority treatments for transit vehicles on Euclid Avenue, improving access and passenger waiting amenities in a specified downtown transit zone, and purchasing and deploying a unique transit vehicle. As part of the roadway and transitway improvements, Euclid Avenue will be reconstructed the entire length of the corridor. These civic improvements include urban design treatments intended to stimulate economic growth and redevelopment. The project was renamed the Euclid Corridor Transportation Project (ECTP). The central element of ECTP is the construction of an exclusive transitway in the median of Euclid Avenue, Cleveland’s main street. The transitway would extend from Public Square east to Stearns Road in University Circle. It would include conveniently located stations spaced approximately every 0.5 mi (0.8 km). Traffic would be controlled by a traffic management system that monitors every signalized intersection and provides priority to detected advancing transit vehicles in the peak direction. The system would function as a bus rapid transit line and would have the capacity to move 90 buses per hour in the peak direction (Figure 1, where 1 mi = 1.6 km).

Currently, four bus routes serve the Euclid Corridor between Public Square and University Circle. Average daily ridership on the bus lines serving the corridor is over 27,600. The average number of daily passenger boardings at Red Line stations serving the corridor is approximately 9,200 riders. This includes eastbound boardings at Tower City. The Route 6 Euclid Avenue local bus has the highest ridership in the RTA system, with average daily boardings exceeding 20,000 riders. This includes riders from the former Route 6A and 28X. Route 6 accounts for more than 54 percent of all transit trips in the corridor. Purpose and Need The greater Cleveland area has experienced population dispersion, low-density development, and continued suburbanization, especially shifts in employment away from

the central business district (CBD). Employment and population migration from the city to surrounding communities is affecting land use and travel patterns. In 1960 the city’s population was 876,000, greater than the combined population of the Cuyahoga County suburbs. And the total population of Cuyahoga County exceeded the combined population of the adjoining counties. By 1990, outward migration reversed the distribution of population. Adjoining counties have a combined population of 1.2 million, Cuyahoga County suburbs have a combined population of 906,524, and the central city population has been reduced to 505,616. This trend is expected to continue in the future, with the Cleveland CBD losing more market share of the region’s employment base. This reversal of population and employment distribution has had a profound effect on public transportation usage. Since 1980, total RTA system ridership has been reduced by more than 50 percent, from 110 million annual riders to about 55 million in 1999. RTA accounts for only 2.2 percent of total daily trips and approximately 10 percent of average daily work trips. The Euclid Avenue BRT element of the ECTP is designed to make a significant improvement in the quality and appeal of transit services in the Euclid Corridor. Fundamentally the project is designed to stimulate economic development in the Euclid Corridor through direct investment of a major infrastructure enhancement and reinvestment in properties adjacent to the BRT stations. Euclid Avenue BRT Attributes The Euclid Avenue BRT consists of a 4.2-mi (6.76-km) exclusive transitway constructed in the median of Euclid Avenue. The typical sections of the Euclid Avenue busway are illustrated in Figure 2. The transitway will feature transit signal priority, automated vehicle location, and passenger information systems. Stations will allow passengers to board unique buses from low-level platforms designed for level entry. The Euclid Avenue buses will be low-floor, articulated ETBs. ETB technology was selected to satisfy the ultraquiet and zero emission standards specified by the city of Cleveland for the CBD segment of the transitway. The ETB will have doors on both sides of the vehicle, similar to light rail vehicles, allowing passengers to board either from the median station platforms in the CBD or from curbside platforms on segments of the route located east of the busway between University Circle and the terminus of the Euclid Avenue BRT line at Windermere Station in East Cleveland. East 17th Street between Prospect Avenue and St. Clair Avenue in downtown Cleveland will be converted to a semiexclusive transitway with local access provisions for general traffic. The Downtown Transit Zone element of the ECTP includes creation of exclusive bus lanes on Superior and St. Clair Avenues between Public Square and East 17th Street to facilitate bus route rationalization in the downtown area. RTA is also examining systemwide changes to its fare collection process to facilitate faster boarding and alighting. The Euclid Corridor BRT and the RTA rail rapid transit system may utilize a proof-of-payment system. Capital Cost Estimate The capital cost estimates for the Euclid Avenue TSM and Rail Build alternatives, in 1994 dollars, are listed in Table 1.

The Dual-Hub Rail Build alternatives 3A and 3B include the relocation of the RTA rapid transit in the downtown area, including some segments of a downtown subway between Public Square and Cleveland State University. Alternatives 4A and 4B include the downtown subway segment and LRT along Euclid Avenue between Cleveland State University and University Circle. Alternative 4B includes a connecting link between the RTA Shaker Heights Blue/Green LRT lines and the proposed Euclid Avenue LRT. The Euclid Corridor BRT has evolved from the Dual-Hub Corridor TSM alternative. The capital cost estimate of the BRT project with supporting elements is approximately $205.4 million. The BRT has an annualized capital cost of approximately $17.8 million. The BRT cost estimates are in 1998 dollars (2). The fundamental differences between the Dual-Hub TSM alternative and the Euclid Corridor BRT are in the levels of reconstruction for Euclid Avenue and the urban design treatments. The Dual-Hub TSM alternative provided for minimum utility improvements and street resurfacing rather than reconstruction of the entire street structure. Operating Cost Estimate The operating and maintenance cost estimates, based on the marginal costs of implementing the TSM and Rail Build alternatives of the Dual-Hub Corridor, are summarized in Table 2. The ECTP No Build operating and maintenance cost estimate is $182.9 million, slightly less than the Dual-Hub No Build alternative. The Euclid Avenue BRT adds only $1.1 million in annualized operating and maintenance costs to the RTA system. The significant difference between the Dual-Hub and Euclid Corridor alternatives can be found in the relative levels of background changes in the bus system networks. RTA instituted a series of route changes and modifications resulting from recommendations made in the 1995 Dual-Hub Corridor study and a follow-up Comprehensive Operations Analysis (COA) completed in 1996. The COA recommendations resulted in decreased operating expenses systemwide. The COA route network became the ECTP No Build transit network.

Ridership Estimates The forecasts for transit ridership are critical to the evaluation of cost-effectiveness. Table 3 illustrates the ridership forecasts for the Euclid Avenue LRT as reported in the Dual Hub Corridor Transitional Analysis (1). The Euclid Corridor Transportation Project average daily linked trips are 167,527 for the No Build alternative and 169,934 for the BRT alternative, which is greater than the ridership predicted for the Dual Hub. The reasons for the differences in ridership estimates between the Dual Hub and Euclid Corridor phases of project development relate to differences in modeling techniques and background transit networks. The ECTP model displays total regional transit ridership, which includes services from adjoining counties. Cost-Effectiveness The cost-effectiveness indices for the Dual-Hub Corridor LRT and Euclid Corridor BRT alternatives were calculated by applying current FTA New Starts guidance in determining the cost-per-new-rider index. The cost-per-new-rider index is calculated by adding the annualized capital cost to the annual change in operating and maintenance costs and then dividing the resulting sum by the change in annual new linked trips. Table 4 illustrates the results of these calculations for the Dual-Hub Corridor. TABLE 3

The Euclid Corridor BRT has a cost-effectiveness index of $26.93. The reason for the increase in the Euclid Corridor BRT cost-effectiveness index compared to the Dual-Hub TSM alternative derives from the design elements added to the BRT system. These added design elements include complete reconstruction of the Euclid Avenue street structure, utility improvements and relocations, electric trolleybus overhead contact system and power distribution, median stations, and significant streetscape improvements. In addition, a high percentage of the ridership increases projected by the Dual-Hub Corridor TSM and Rail Build alternatives are accounted for in the ECTP No Build alternative. Therefore the net increase in transit riders is lower for the Euclid Corridor BRT when compared to the Dual-Hub TSM and Rail Build alternatives. The Euclid Corridor BRT has a slightly lower cost-effectiveness index than the Dual-Hub Rail Build alternatives. However, a more direct comparison of the two projects is needed. Euclid Corridor BRT Compared with Dual-Hub Corridor LRT Because of the subtle and not insignificant differences between the Euclid Corridor BRT and Dual-Hub Corridor LRT alternatives, it is necessary to use some judgment in evaluating the two projects. It is clear from Table 4 why the TSM alternative was selected as the locally preferred alternative. The lower cost-effectiveness index convinced local officials that improving bus service in the corridor was more cost-effective than building a new downtown subway and LRT along Euclid Avenue. Moreover the annual increases in operating costs made the LRT alternative prohibitively expensive to operate. Table 5 illustrates a more direct comparison between the two projects. The cost estimates for the Dual-Hub Corridor alternatives have been adjusted to 1998 dollars. The ridership estimates for the Euclid Corridor BRT have been adjusted to add the new transit riders gained as a result of using the Dual-Hub Corridor TSM transit network as the ECTP No Build transit network. Consequently, BRT is nearly twice as cost-effective as LRT. TABLE 4 Estimated Dual-Hub Project Cost Effectiveness (Annualized Costs and Ridership in Thousands)

TABLE 5 Comparison of Euclid Corridor BRT and Dual-Hub LRT Project Cost-Effectiveness (Annualized Costs and Ridership in Thousands)

The significant comparative differences in capital costs between the LRT and BRT projects are directly attributable to the cost of constructing imbedded track structure, subway connections to the existing Red Line in downtown Cleveland, utility relocations, and the purchase of light rail vehicles. NASHVILLE URBAN CORE BRT The Urban Core Light Rail Analysis (3) was a feasibility study conducted by the Nashville Metropolitan Transit Authority to examine the phased development of LRT in the downtown Nashville to West End travel corridor. This dense urban core travel corridor is experiencing rapid growth in employment and in special-event and tourist-oriented travel (Figure 3, where 1 ft = 0.3 m). The attractiveness of an urban light rail transportation link is based on both present and future land uses that have the capability of generating considerable traffic within the corridor. The urban core LRT would link downtown, Music Row, West End, and the redeveloping East Bank area including the historic Edgefield neighborhood. The specific objectives of this study were to: • Determine how light rail transit can serve downtown employment centers and tourist-related attractions within the study corridor without precluding future extensions to East Bank neighborhoods and other areas of the region; • Determine the optimum alignment, technology, and operating plan; • Determine the capital and operating costs; • Determine the number of potential riders who would use the service; and • Determine the overall financial feasibility and cost-effectiveness of implementing LRT.

Nashville urban core map.

Purpose and Need The five-county Nashville metropolitan area is growing in population and employment. Central Nashville, which is primarily Davidson County, has grown 28 percent since 1960 and is projected to grow another 15 percent between 1990 and 2015. From 1980 to 1990, the Nashville region experienced a 26 percent increase in employment. Employment in the region is projected to increase another 39 percent between 1990 and 2015. In addition, the growth of the tourist and convention industry stemming from the growing popularity of country music worldwide is placing additional stress on the existing transportation system. The number of trips made by people living in the region has grown and will continue to grow as development becomes more automobile oriented. People travel farther distances because of the ever-expanding geographic area, typical of urban sprawl development patterns. The size of the region and the diversity of destinations is one of the primary reasons automobile travel in the area is so prevalent; cars are much more convenient for reaching the variety of suburban destinations. Nashville has over 490 lane-miles (788.9 lane-km) of multilane express highways. A great deal of this highway infrastructure investment was made by the community to foster economic development and to improve the quality of life for area residents. There are many major arterial roads that radiate from downtown. This roadway pattern reflects

the historical development trend associated with the settlement of Nashville. Some of the arterial roads and expressways in the corridor could become overutilized by the year 2015. This means the highways would operate poorly, with significant delays during peak travel periods. Consequently, existing transit bus service in the corridor, which is locked into the radial layout of the major streets in Nashville, will suffer serious degradation of service quality in terms of passenger travel times and schedule reliability. Nashville BRT Features The urban core BRT system is envisioned to consist of exclusive bus lanes on West End Boulevard and several downtown streets. A high level of transit priority signaling would speed the buses through the corridor. The buses would be low-floor articulated ETB, with design characteristics similar to light rail vehicles. The buses would be ultraquiet and nonpolluting, and they would provide a higher level of passenger comfort when compared to today’s motor buses. Stations would be simple in design and blend aesthetically with surrounding neighborhoods. The 4.2-mi (6.76-km) starter line would begin on the east bank of the Cumberland River at the new Tennessee Titans Stadium and end at I-440 near Murphy Road. There are 15 potential stations located to serve areas thought to generate the highest potential ridership. Stations were sited at intersections with bus routes and major urban arterials or in proximity to high concentrations of residential or employment activity. Stations serve the CBD, the Arena and Convention Center, Music Row, and Vanderbilt University. Connections to planned commuter rail stations were also considered. Capital Cost Estimate As part of the feasibility study, two capital cost estimates were prepared, one for LRT and one for BRT. The estimated total capital cost of the LRT is $114.5 million. The capital costs of constructing the BRT using ETB technologies were estimated to be approximately $53.5 million. This represents a 53 percent reduction in the capital cost while achieving the same transportation utility as measured in speed and potential travel time savings. Table 6 clearly shows that the cost savings are achieved by eliminating the track structure and utility relocation necessary for imbedded track construction. Operating Cost Estimate The estimated operating and maintenance costs for LRT were determined to be approximately $4.6 million annually. This equates to approximately $18.28 per LRT car-mile. The national average cost per LRT car-mile for light rail service is $19.35. Because the BRT service schedule would be identical to the LRT schedule, it would provide the same vehicle-miles. However, the operating costs would be lower than LRT. The BRT system would be operated as an extension of the MTA bus service, thereby saving some managerial, engineering, and track maintenance positions. It is estimated that the BRT operations and maintenance expenses would be approximately $3.2 million annually. This is equivalent to approximately $12.73 per bus-mile, very similar to the ETB operating and maintenance costs experienced by Seattle and San Francisco.

However, the cost per passenger-mile is potentially lower for the LRT service because it has greater passenger-carrying capacity. Although the LRT system is desirable strictly from its ability to carry higher volumes of passengers, the 53 percent increase in capital costs to achieve this result doesn’t appear justified when potential ridership on the starter line is examined. Ridership Estimated ridership on the Nashville urban core line would be approximately 5,500 average daily riders, growing to approximately 9,500 in the future. This figure includes estimated annual special-events ridership averaged on a daily basis. The relatively short urban core line does not penetrate deeply into denser residential neighborhoods and must depend entirely on park-and-ride, feeder bus, and Vanderbilt University student ridership. There is no significant difference in ridership between LRT and BRT modes. Cost-Effectiveness The Nashville Urban Core Light Rail Analysis (3) examined the cost-effectiveness of both LRT and BRT alternatives by applying current FTA New Starts guidance in calculating the cost-per-new-rider index. The LRT alternative has a cost-per-new-rider index of approximately $28.57. The BRT ETB alternative has a cost-per-new-rider index of approximately $16.22. CONCLUSION The concept of BRT has been embraced by some cities as the most cost-effective solution to growing demand for improved public transportation that is neither just a bus nor an expensive LRT line. This is especially true in Brazil and France, where new ETB and GLT systems have been developed as either a substitute or a precursor to LRT. In Cleveland, Ohio, the substitute Euclid Corridor BRT alternative is nearly twice as costeffective as the ill-fated Dual-Hub Corridor LRT line. In Nashville, transit authority and city officials are examining the merits of an ETB BRT alternative as a precursor to a more expensive LRT option. In the case of Cleveland, the Euclid Corridor BRT option costs more than $504.3 million less than the Dual-Hub 3B LRT option in comparable 1998 dollars. The differences in annualized costs and new transit riders between the BRT and LRT options equates to approximately $41.39 per new transit rider. The Nashville BRT option costs $61 million less than the LRT option. There is no significant difference in ridership estimates for the BRT and LRT option in Nashville, making the BRT option very costeffective. REFERENCES 1.
