Design and Evaluation of Impact of Traffic Light Priority for Trucks on Traffic Flow
| 项目名称： | Design and Evaluation of Impact of Traffic Light Priority for Trucks on Traffic Flow |
| 摘要： | Under this project the plan is to investigate the impact of giving priority to trucks at traffic lights not only on the travel time of trucks but also on the travel time of passenger vehicles. The concept is similar to that of giving priority to buses even though the motivation for doing so for trucks is different. By timing the traffic signals to give priority to trucks when trucks are present we can achieve two benefits. First the trucks will clear the intersection faster without having to make frequent stops that introduce additional delays due to the time it takes for a truck to accelerate from zero speed to a desired speed and second the less decelerations/accelerations a truck goes through the less pollution it generates and the less fuel it consumes. Such traffic light priority may also have beneficial effect on the travel time of passenger vehicles due to elimination of delays caused by trucks stopping and going. The project analysis is to reveal these benefits and possible tradeoffs. |
