PREFACE Effective transportation of people and goods has become the cornerstone of development as it has been noticed from the experience of various countries. Mobility is an engine of growth and transportation systems have to be dynamic to meet the growing requirements.

The process of urbanization is fastest in the developing world and it

should be viewed as a reflection of the inexorable surge of the forces of development. This development has resulted in most of the cities a mismatch between capacity and traffic demand and this is too acute in peak hours.

The complexity of urban

transportation and increased travel continues to challenge the experts across the globe. In the face of growing travel demand, issues on sustainable transport, increasing air pollution, safety and efficiency of transport systems etc. are coming into prominence. Transportation systems are an integral part of a modern day society designed to provide efficient and economical movement between the component parts of the system and offer maximum possible mobility to all elements of

society.

A competitive, growing

economy requires a transportation system that can move people, goods, and services quickly and effectively. Road transportation is a critical link between all the other modes of transportation and proper functioning of road transportation, both by itself and as

a

part of a larger interconnected system, ensures a better performance of the

transportation system as a whole. Traffic control and management facilities are imperative for the economic, safe and efficient transportation in city roads. Signalized intersections, as a critical element of an urban road transportation system, regulate the flow of vehicles through urban areas. Co-operative republic of Guyana is experiencing development activities of late and supporting infrastructural developments are planned. Government of India is helping the people and government of Guyana in its endeavour of developing the transport infrastucture. This project aims at installing advanced traffic control systems at major intersections of road network in George Town. Reconnaissance surveys, traffic volume surveys, preliminary parking and public transport surveys are conducted as part of this study.

ABSTRACT A traffic engineering survey was undertaken in George Town, the capital city of Cooperative Republic of Guyana towards installation of advanced traffic control systems. This report is prepared on the basis of analysis of traffic flow details and other data collected during number of field visits and covers the findings and recommendations of the study. Intersection drawings of fifty intersections are prepared by conducting total station survey and attached in this report. Geometric improvements for intersections are suggested along with details of signalisation.

Classified directional Traffic volume

surveys are conducted at intersections. It was found that

percentage of cars are

varying from 52 to 79 at various intersections. Mini buses, which are the main form of public transport in George Town consists of 14 to 34 % of traffic at various intersections. Volume capacity ratio at many intersections are nearing over saturation levels. It is observed that Camp street and Regent street junction has a v/c ratio of 0.89. By the year 2011, v/c ratio at this intersection is projected to cross one and before that geometric modifications are to be strictly implemented at this junction and many others .

A

projection of traffic volume at number of intersection indicate number of intersections need to go for geometric improvements in the near feature. Pedestrian footpaths are not continuous and pedestrians have to often travel through roads increasing the conflict. A separate pedestrian stage is proposed at all intersections to increase the pedestrian safety. Mini buses, doing the mantle of public transport, don’t have terminal facilities and hence create traffic congestion and chaos by parking in sides of roads and Stabroek market area. Proper terminal facilities need to be provided to Mini buses by properly utilizing vacant land in the nearby areas. Optimised signal time plans for signals working on fixed time plans are generated using Traffic Network Study Tool (TRANSYT). In some corridors, adjacent signals are coordinated and the coordinated signal time plans are also developed. This report also gives the theoretical frame work on feasibility study on traffic signals, geometric improvement of junctions, signal time plan selection etc.

CHAPTER 1 INTRODUCTION The Cooperative Republic of Guyana is located on the northern coast of South America, with Suriname to the east, Brazil to the South, Venezuela to the West and the Atlantic ocean to the north. Guyana is medium sized country with an area of 215,000 sq. km and a population of approximately 750,000. Almost 90 % of the population lives on the coast, whereas the remaining live in the hard-to-reach hinterlands. The demographic growth is very low, because the high emigration (1% - 1.7% annually) neutralizes the natural growth. Guyana is a small economy endowed with natural resources like gold, diamonds, bauxite, fertile land, and large tropical forests. Despite its natural resources, and welleducated population, Guyana is the fourth poorest country in the Western Hemisphere, ranked 169 among countries of world with a GDP of

US$ 3,620,000,000 (in PPP),

having a per capita income below US $ 1,000. Guyana is undergoing a paradigm shift on its development path from an agricultural and mining economy to one with services, manufacturing and construction. Services and industry combined together contribute 63 % to GDP. Number of highways, hydro power generation, ports, tele communication networks, IT Parks, pharmaceutical facilities, aqua farms, fish farms etc. are being developed as part of a resurgent economy.

It is

imperative in the quest for development of the country to give more attention on its roads which are vital for movement of people and goods and ensuring this a safe, efficient, speedy and economical one. George Town, the capital city of Guyana is the centre of government administration and a wide range of economic activities (Figure 1.1). Network of streets in GeorgeTown are laid in rectangles, see Figure 1.1, legacy of its Dutch colonial heritage making it easy for alternate traffic movement routes. Commercial activities are mostly centered around Camp street, Water street, Lamaha street and Brickdam street as the east, west, north and south limits respectively. There is an increasing number of business establishments in the surroundings of Camp street in Regent street

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ Public transport is mainly catered by mini bus services which operates in allocated routes with well regulated fare structure which might have been developed as a part of the narrow roads and un flared intersections in George Town. The network of routes has number of starting points which are concentrated in the Stabroek market area and along the Avenue of the Republic between Croal and Robb streets .

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ Of late number of intersections in George Town are facing acute traffic congestion and the Government of Guyana and Ministry of Public works and communication felt the need for implementing advanced traffic control measures along with traffic management measures with the help of Government of India as part of improving transportation infrastructure of the country 1.1 Objectives of study 1. Understand the traffic problems at various intersections in GeorgeTown 2. Suggest traffic management plans and intersection improvement plans 3. Physical set off diagram for intersection equipment like poles, signal aspects etc. 4. Recommend optimized signal plans and coordinated signal plans for various intersections 1.2 Scope of work The scope of the work covers the following 1. Reconnaissance survey of various areas and intersections in George Town 2. Traffic volume survey at intersections to understand the traffic flow patterns at different time periods of the day 3. Total station survey of various intersections to detail the junction geometry 4. Analyse the volume capacity ratio at critical intersections 1.3 Methodology Traffic volume surveys are conducted and the traffic volume details are checked for feasibility of signals as per the guidelines by MUTCD. Once the intersections are selected, Total station survey was conducted to map the intersection to scale.

All

intersection inventories up to 100 m on all arms of intersections were mapped. Traffic volume in vehicles was converted into equivalent

Passenger Car Units (PCU).

Saturation flow was estimated on the basis of approach width. For right turn proper adjustments are given to the saturation flow. Volume capacity ratio was found out and recommendations on capacity augmentation are made. Optimum signal time plans are generated by using Traffic Network Study Tool (TRANSYT) software. Geometric improvement plans are suggested in line with AASHTO guidelines.

CHAPTER 2 TRAFFIC SURVEYS AND GEOMETRIC SURVEY AT INTERSECTIONS IN GEORGE TOWN 2.1 Preliminary field survey Preliminary field survey to important intersections in George Town was done. Various aspects of intersections like traffic volume, interruption to main traffic volume, pedestrian traffic, accident experience, nearness to schools, hospitals etc. are verified for ascertaining the requirement of traffic signals. Information on Parking , public transport etc are also covered during this survey.

2.2 Traffic volume survey Classified directional traffic volume surveys are conducted at critical intersections among the intersections selected for signalsation. Vehicles are classified into various categories and each enumerator was given the task of counting the vehicles in that category in one particular direction. Fifteen minutes interval counts are done. As the survey period was restricted, the survey was limited to critical intersections.

Number of enumerators are

assigned the task of counting vehicles during peak hours. Format used for survey is shown in Annexure 1.

Figure 2.1 Traffic Volume survey in progress

2.3 Total station survey Total station survey was conducted at fifty selected intersections.

All physical

inventories at 5m. interval was mapped. For a distance of 100 m in all approaches. Some

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ intersections which are too close and less than a distance of 100 m are surveyed together . Drawings are prepared to a scale of 1:1000 and shown in the later parts of this report.

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ Classified directional traffic data collcted at fifteen minutes interval are tabulated and converted into equivalent PCU values and directional flow was found out.

Each

directional volume was added to get total junction volume. Tabulated values of classified directional traffic volume surveyare given in Annexure 2. Capacity of the junction is found out by using saturation flow estimation methods and the present control methods. By knowing the traffic cvolume and capacity v/c ratio for various intersections are estimated. Traffic volumes are projected for five years and v/c values are estimated. Traffic volume values are further used for generating the signal time plans. Some adjacent signals falling on the same road are co ordinated for an average platoon speed and offsets are recommended accordingly.

CHAPTER 3 TRAFFIC CHARACTERISTICS OF GEORGE TOWN 3.1 Present Traffic conditions Most of the roads of George Town are two to four lane roads. Traffic is nearing saturation levels at many intersections at certain times of the day, with flows of up to 15,000 vehicles per day, on some roads. (Guyana Transport Sector Study, 2005). Long queues of vehicles can be seen at number of intersections as on Camp street Regent street junction (Photo 3.1a&e). Road side parking significantly affects the capacity of roads at many places(Photo 3.1a inset). Eventhough cars constitute more than 50 percent of vehicular traffic, a sizeable percentage of mini buses and light commercial vehicles are also plying through the roads inGeorge Town. (Photo 3.1b). At many places, the surface conditions and drainage facilities are far from adequate near to intersections increasing the chaos on the roads (Photo 3.1c). Lack of terminal facilities for mini buses, the main public transport facility available in George town accentuate the traffic conditions in the Avenue of the Republic Road, Straboek market area and near Parliament house building (Photo 3.1d). Pedestrian amenities are far from adequate. Continuous footpaths for pedestrians are not available forcing pedestrians to use the road increasing conflict with vehicles and accident potential. Traffic signals installed at some locations are damaged and not working (Photo 3.1g). Congested junctions are controlled by traffic police during peak hours (Photo 3.1 f) Around 2,800 minibuses are licensed to operate as public transportation Guyana. Some 2,200 of these minibuses operate from Georgetown, with 3 routes entirely within the City and a further 9 routes travelling out through to the city to suburban and distant destinations. The three city routes [routes 40-41-45] have 445 authorised vehicles, whilst the nine other routes from destinations beyond Georgetown have the residual 1,777 vehicles. The three city routes operate at very high frequency during peak periods. Operations [together with those from outside the City] are distributed on the streets around the Stabroek Market area in central Georgetown. However, this area is also a major market for traders, is close to the Cross-estuary fast ferries, is shared with building

There are no purpose built passenger waiting areas, nor are there orderly loading arrangements. In short, the area and facilities are far from ideal for public transport. (Guyana Transport Sector Study, 2005) Annual Average Daily Traffic for George Town to Buxton road and George Town to Golden Group road in 2001 was found to be 10948 and 13997 respectively. The growth of road traffic can generally be related to expected economic growth, and to an assumed elasticity of transport demand, which may have different values for passenger and goods vehicles. The Guyana Transport Sector Study has adopted a road traffic annual growth rate of around 3 per cent after considering the economic growth, passenger growth, goods traffic etc.. Appropriate traffic management measures and application of sound urban transport planning principles could make significant improvement in traffic flow, road safety and public amenity in the central area. Guyana Transport Sector Study (Guyana Transport Sector Study, 2005) has identified problem with the urban road capacity in Georgetown, which could most probably be handled by traffic management measures in the short to medium terms, for which a detailed study was recommended. It further states that in the medium term, attention may need to be given to the possibility of developing a ring road system to improve traffic flow and to avoid congesting the central area. The future planning requirement in respect of the City Port operations and the DHB River crossing will be investigated through further Feasibility study. (Guyana Transport Sector Study, 2005) According top this report, specific national strategies for urban and public transport and for traffic management were not seen. Private car ownership is low by international standards yet traffic congestion in Georgetown already creates conflicts regularly during peak periods every working day. The gradual growth of car ownership will incrementally and adversely affect this congestion so it is timely to recognise that the setting of standards and their implementation in guiding urban structural planning and strategic transport planning is important if orderly absorption of growth is to be achieved.

3.2 Public Transport Mini buses are the most common form of public transport found in George Town. The smaller size of the vehicles suit the geometric conditions of roads and intersections. At present there are no boarding facilities for passengers forcing the vehicles to make use of road space creating chaos and confusion in the roads and inconvenience to commuters. Terminals of this mini bus services are shown in Figure 3.1. It can be seen that most of these are falling in the Stabroek market area and Avenue of the Republic road side.

3.3 Traffic flow characteristics in GeorgeTown Traffic volume surveys are conducted at some critical intersections in George Town. Peak hour flows are in the periods of 07.00 hrs to 09.00 hrs. Noon peak hours are between 11.00 hrs to 14.00 hrs. Evening peak hour are from 16.00 hrs to 19.00 hrs. Percentage of cars is varying from 51.77 % at Cummins street and Regent street to 79.02% at Avenue of the Republic and Brickdam street. Percentage of Mini buses was found to vary from 15.36% at Vlissengen road and Home stretch junction to 28.19% at Cummins street and Regent Street junction. Percentage of motorized two wheelers is varying from 3.98% to 10.82%. More details on composition of traffic flow are shown in Figure 3.2 a and Figure 3.2 b Traffic flow details of various intersections are shown in Annexure 2

3.4 Volume Capacity ratio at intersections An analysis of traffic volume and capacity ratio (v/c) of some critical intersections is done. It was found that many junctions are nearing saturation levels.

It is widely

accepted that if the v/c ratio is above 0.9 the junction is over saturated. More details on v/ c ratio of various intersections are discussed in Chapter 6.

CHAPTER 4 FEASIBILTY OF TRAFFIC SIGNALS 4.1 General Requirement of signal at a junction need to be determined only after a competent engineering study of the location is undertaken and a decision made based on sound engineering judgment. The initial step consists of a quick review of the existing traffic volume data and accident records.

Field visit is necessary to observe the existing

conditions and intersection geometry Requirements of traffic signals as per the guidelines fixed by Manual of Uniform Traffic Control Devices (MUTCD) have been checked. A preliminary comparison of the MUTCD warrants and the traffic volume details at number of intersections in the city centre shows that signals are needed at number of intersections. Traffic volume details collected from field surveys are used to verify the warrants of the signals

4.2 Warrants for Signals The ITE warrants are shown in Table 4.1 The requirements of one or more of these warrants should be satisfied before a signal is installed. In addition to the warrants mentioned in Table 4.1 there are others like the following are also to be considered before reaching a final decision on the installation of road traffic signal. 1. 2. 3. 4. 5. 6. 7. 8.

School crossings Progressive movement Accident experience Systems Combination of warrants Four hour volume Peak hour delay Peak hour volume

CHAPTER 6 CAPACITY ANALYSIS AND OPTIMISED SIGNAL TIME PLANS 6.1 Capacity of a signalized network of roads A critical need in traffic analysis is a clear understanding of the ability of various types of transportation systems facilities to carry traffic. This knowledge when integrated with the measurements of present traffic volume and forecasts of future traffic demand allow traffic engineer to plan and design facilities that can cater to the needs of society. Capacity of a facility is defined as the maximum hourly rate at which persons or vehicles can reasonably be expected to traverse a point or uniform segment of a lane or roadway during a given time period under prevailing traffic, roadway and control conditions. An analysis of volume capacity ratio gives the measure of sufficiency of capacity. A v/c ratio of more than one indicates lack of capacity and the need for improvements.

6.2 Volume Capacity ratio (v/c) analysis of intersections in George Town Capacity analysis of fifty intersections in George Town is done. This was done after measuring the geometry of the junctions and assuming the present control plans with some approximation.

Details are given in Table 6.1 along with capacity with the

suggested modifications. Table 6.1 Capacity of intersections in GeorgeTown Sl.No.

Traffic volumes of intersections are projected for the coming five years and the v/c ratios are found out. V/c ratio should be less than 0.9 to consider for the increase in traffic volume in some times.

It is found that number of intersections are nearing over

saturation and if capacity augmentation by way of geometric improvements are not done, delays at intersections in GeorgeTown are going to increase in the coming years.

6.3 Signal time plans Performance of fixed time plans depends to a great extent on up to date signal plans developed based on the traffic volume details Timing Parameters Any discussion of signal timing usually provides the basic definitions of the common terms used to depict the various aspects of timing parameters.

________________________________________________________________________ 148

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ Cycle: The time required for one complete sequence of signal indications Stage/Phase: That part of a signal cycle allocated to any combination of one or more traffic

movements simultaneously receiving the right of way during one or more

intervals. Interval: A discrete portion of the signal cycle during which the signal indications remain unchanged. Offset: The time difference between the start of the green indication at one intersection as related to the start of the green indication at another intersection or from the system base. Split: The percentage of a cycle length allocated to each of the various phases in a signal sequence. General Considerations The functional objective of signal timing is to alternate the right of way among the various phases in such a way as to: Provide for the orderly movement of traffic Minimize average delay to vehicles and pedestrians Reduce the potential for accident-producing conflicts Maximize the capacity of each intersection approach

Timing for Pretimed Control There are several fundamental aspects of developing timing settings for pretimed signal control. The essential elements include: Number of timing plans Phase change intervals (yellow change plus all-red clearance) Pedestrians timing requirements (including decision whether or not to use pedestrian indications) Cycle length calculations

________________________________________________________________________ 149

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ Split calculations Flashing operation Timing Plans A timing plan may be defined as a unique combination of cycle length (commonly ranging from 40 to 120 seconds), split, and, in system operations, offset. Microprocessorbased controller hardware is generally capable of a total of 12 plans (a combination of at least four cycles and three splits)-one per dial. Traffic demand at the intersection is the critical determinants of the number of timing plans required. Traffic demand patterns typical of a majority of locations may be categorized as: A.M. peak period Average day (midday) period P.M. peak period Night (low-flow) period Weekend or special function periods The directional lane demand is the number of vehicles in the heaviest used lane or, as a simple estimate, the approach count divided by the number of lanes in that approach. After the directional demand (normalized to land demand) is established, the following computation can be made for total intersection demand: TD = ( N , S ) max + ( E , W ) max where

TD = total intersection demand ( N , S ) max = maximum demand, either northbound or southbound ( E , W ) max = maximum demand, either eastbound or west bound

for cross-directional demand, the computation is as follows: CD = ( N , S ) max / TD or CD = ( E , W ) max / TD where CD = cross-directional demand. Phase-Change Interval

________________________________________________________________________ 150

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________ The phase-interval may consist of only a yellow change interval or may include an additional all-red clearance interval. The critical function of the phase-change interval is to warn traffic of an impending change in the right of way assignment. The Uniform Vehicle Code defines the yellow change indication as follows: Vehicle traffic facing a steady yellow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter when vehicular traffic shall not enter the intersection. In those states that follow the Uniform Vehicle Code, the yellow change interval is computed to provide adequate time to alert drivers of the need to stop for the forthcoming red light. In some states, vehicles are not permitted in the intersection when the light turns red and may be cited for a traffic violation. In this case, a “dilemma zone” can be physically stop not legally proceed. Timing the phasechange period, therefore, should take into account the legal definition as well as the local traffic conditions. The following equation may be used to calculate the phase-change interval, considering driver reaction time, acceleration requirements, and intersection clearing time.

CP = t +

V W +L + V 2a

where Cp = non dilemma change period ( yellow plus all red), s t = perception-reaction time (usually 1s) V = approach speed, m/s a = deceleration rate, m/s2

W = width of intersection, m L = length of vehicle, m Adding the effects of grade in above equations yield following CP = t +

V W +L + 2a + 64.4 g V

________________________________________________________________________ 151

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________

where g = percent of grade divided by 100 (plus for upgrade, minus for downgrade). Pedestrian Timing Requirements

Pedestrian movements across signalised intersections are typically accommodated by one of the following operational options: Pedestrian cross the street with the parallel vehicular green indication (no pedestrian signal display). Pedestrian movements are controlled by a concurrent separate pedestrian signal display. Pedestrian move on an exclusive phase while all vehicular traffic is stopped. The essential factor in any of these options is to provide adequate time for the pedestrian to enter the intersections (walk interval) and to safety cross the street (pedestrian clearance interval). In case where there are no separate pedestrian displays and the pedestrian moves concurrently with vehicular traffic on the parallel street, the time allocated to vehicular traffic must consider the time required for pedestrians to react to the vehicular green indication and move across the street. When separate pedestrian displays (WALK, DON’T WALK) are used, the minimum WALK interval generally ranges from 4 to 7 seconds (as recommended by the MUTCD, Section 4D-7). This allows the pedestrian ample opportunity to leave the curb before the pedestrian per cycle, the lower 4 second WALK interval is usually adequate. Cycle-Length Calculations

The time required to complete a prescribed sequence of phases is known as the cycle length. There are various techniques that may be applied to establishing cycle length. One procedure was developed by Webster based upon computer simulation and field observation. His equation for optimum cycle length that minimizes delay is as follows: C=

1.5L + 5 1.0 − Yi

where, C = optimum cycle length, s

________________________________________________________________________ 152

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________

Yi =

critical lane volume (ith phase, vph) saturation flow, vph

L= unused time per cycle, s = nl + R n = number of phases

l = average lost time per phase, s

R = total all-red time per cycle, s The value of L is often the sum of the yellow and all-red intervals for all phases, particularly in states where the yellow is legal “go” time. In other states, an extra 1 or 2 seconds per phase may be added. Saturation flow (the denominator of Y) may be measured in the field, but is frequently set to 1800 vehicles per hour. Some jurisdictions use lower values (e.g., 1500 vph). Table 6. 3 Minimum Pedestrian Clearance intervals

6.4. Traffic Network Study Tool (TRANSYT) Number of softwares is available for the development of optimized signal time plans. Traffic Network Study Tool (TRANSYT) is software developed by Transport and Road Research Laboratory (TRL) U.K. to find

optimized signal time plans in a signalized

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________

road network. The TRANSYT simulation/optimization model serves as an unofficial international standard against which many measure the efficiency of other methods of coordinating networks of traffic signals that operate at a constant and common cycle length. TRANSYT has an off-line macroscopic, deterministic, simulation and optimization model that simulates traffic as Cyclic Flow Profiles (CFP) and traces the flow of the CFP from link to link throughout the network. The model makes systematic changes to the offset, phase split and cycle length of the traffic signals, and also simulates the associated traffic conditions to estimate a corresponding Performance Index (PI). PI is a linear combination of vehicle delay and number of vehicle stops. For each candidate signal timing parameter the model then uses a hill climbing technique to systematically search for the settings that minimize the PI. The simulation module within the TRANSYT model is a critical component of the model as it evaluates the objective function that is to be minimized. Inputs needed for TRANSYT are 1. Traffic flow in links In TRANSYT, one link represent a distinct a queuing situation that occurs. One link may represent two or more lanes, provided that traffic is equally likely to join the queue in any of the lanes and that identical signal indications are shown to these lanes. 2. Cruise times and cruise speeds Cruise times and cruise speeds are the un delayed times (or speeds) for traffic traveling from each upstream stop line to the stop line on the link defined. 3. Saturation flow Saturation flow at a stop line is the maximum rate of discharge from a queue. It can be obtained by the measurement or calculation based on stop line width and other factors. 4. Stage change time

________________________________________________________________________ 154

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________

TRANSYT models the operation of signal control at each node by reference to stage change times. A stage change time is the time at which the green signal on one stage is terminated and the change to the next stage green period is initiated. Saturation flow has been assumed as 1800 pcu/hour/lane. Traffic flow during peak hours at critical intersections has been found out from traffic volume survey. 5. Signal values for whole network The cycle time for the whole network is specified in seconds. The effective start green displacements and end green displacements are specified as per the field conditions. 5. Signal values for each stage Stage change times are given in seconds, up to seven stages can be specified. Minimum green time for the stage can be given as a constraint. Pedstrian stage length used by TRANSYT is the minimum time 6. Signal values for link During one cycle a link may have one or , optionally, two green periods during which outflow occurs. These green periods need not be the same length, but will have the same value of saturation flow.

The time at which the green begins is specified by a

start stage number and a start lag of a fixed number of seconds. Similarly, the time at which green ends is specified by an end stage number and the effective green can be extended by use of an end lag.

6.5 Optimised signal time plans Optimised signal time plans for various intersections, generated by using TRANSYT runs and stage patterns for vehicle actuated signals are shown in Table 6.4 to Table 6.53 . Co-ordination plans for Camp Street, Mandela Avenue and Vlissengen road are shown in Figure

6.3, 6.4 and 6.5 respectively.

All signal

plans provided here should be fine tuned to field conditions at the time of implementation.

Traffic Engineering and Management Plans for fifty intersections in George Town ______________________________________________________________________

6.6 Operation of Signal time plans The successful operation of a fixed time signal system depends greatly to the allotment of time to various streams of traffic at the intersections. The timing plans generated need to be fine tuned to suit the field conditions. Variations in a week and other seasonal variations can be incorporated in the signal time plans to increase its efficiency. A flow chart for the implementation of the signal timing plans are shown in Figure 6.6. Trigger Event

CHAPTER 7 CONCLUSION A traffic engineering study at fifty intersections in George Town covering

studies on

junction inventories, traffic volume, parking , public transport etc. was undertaken as part of the advanced traffic control systems installation project. A total station survey was conducted to prepare layout of intersections. It is estimated that approximately 62 % of traffic volume comprises cars and

23% are mini buses. Motorised two wheelers

constitute 8% of traffic volume. Peak hour traffic flow in morning are between 07.00 hrs. to 09.00 hrs . Footpaths at many stretches of the road are not continuous, forcing pedestrians to move through roads increasing the conflict with motor vehicles. Terminal facilities of mini buses are not available resulting in the parking of these vehicles near to intersections causing delay to moving traffic . Proper terminal facilities for the mini buses are to be provided after acquiring vacant land like the one near Guyana Power office building on Avenue of the Republic Capacity analysis of fifty intersections selected for signalization was done. Optimised signal time plans are generated for various junctions by using TRANSYT software. Coordinated signal time plans are also generated using TRANSYT for selected signalized corridors. Volume capacity analysis of the fifty intersections was done and it was found that number of intersections are reaching saturation level. Volume capacity analysis with the proposed signal installation and geometric improvements has resulted in lesser values indicating improvement in the situation. With an estimated traffic growth of 3 % per annum, most of these junctions have to undergo geometric improvements in the immediate future to avoid traffic congestion.
