ALTERNATIVE OBJECTIVES IN ARTERIAL-TRAFFIC MANAGEMENT

An arterial traffic management model has been developed by modifying an existing model--TRANSYT 6. The new model--TRANSYT 6C--includes fuel-consumption and vehicle-emission impacts, spatial and modal demand responses, and an extended multiple-objective function for traffic-signal timing. Four traffic management strategies were evaluated in a variety of operating environments. The timing of traffic signals to minimize passenger delay and the use of exclusive bus lanes are the two strategies that best meet the objectives of increased passenger mobility and minimal environmental impacts. A series of sensitivity tests was conducted to determine the effects of different objective functions for traffic-signal timing. Minimizing passenger delay and minimizing fuel consumption were the most effective single-impact objective functions evaluated. Tests in which the length was varied indicate a trade-off in impacts: short cycle lengths minimize total delay and vehicle emissions, and longer cycle lengths tend to decrease priority-vehicle delay, total stops, and fuel consumption. /Authors/
