通过对信号交叉口延误模型的研究,提出了一种新的相位配时优化算法。此算法是将遗传算法引入到延误模型中,以信号交叉口车辆的平均延误最小为目标,考虑交叉口服务水平等多方面的限制,建立新的模型算法,并将其应用于常州市的典型交叉口,获得较好的优化结果。
The delay models of vehicles at signalized intersections are studied and a new phase timing optimization is proposed.This paper proposes the Genetic Algorithm(GA) to optimize the delay models.The goal is to minimize the average delay of vehicles at signalized intersections and considering the service level of intersection and other restrictions.For this a new model is established.The method mentioned in this paper is applied to the actual intersection in Changzhou city.
