The optimization of signal timing at port-highway intersections considering queue at the port gate

Abstract

With the acceleration of the port development process, the traffic problem of port area is becoming more and more obvious. In order to improve the traffic operation efficiency and environmental benefits of intersections, the intersection adjacent to the port and the port gate are approximately regarded as a system, and the signal timing optimization model is established by comprehensively considering the factors such as vehicle queue at the port gate, vehicle delay and capacity, emissions and so on. Combined with an example, the signal timing scheme is improved. The simulation evaluation is carried out by using VISSIM. The results show that the model in this paper can alleviate the queue problem at the port gate, reduce the vehicle delay, improve the capacity and alleviate the problem of pollutant emission, and the model has a good signal control effect.
