| 摘 要： | 城市道路交叉口各交通方式构成比例不同，对控制方案需求不一. 针对各种交通方式混行的信号控制交叉口，考虑道路使用率、出行者时间效率以及环境效益之间的协调关系，结合多目标规划模型的思想，以通行能力最大、车辆停车率及出行者平均延误最小为目标，以饱和度为约束条件，建立交叉口信号配时多目标优化模型. 根据不同交通状态下，各交通方式混合比例确定各性能指标的重要程度，最后运用遗传算法进行求解. 计算结果表明，配时参数多目标优化模型在综合性能指标下优于Webster算法，而且能较好地适应各交通状态的变化，使快、慢行交通协调运行.

| Abstract: | Considering the coordination between vehicle and non-motorized,different traffic composition have different signal control operates at the urban road intersection.In view of the multi-objective property of urban traffic signal control,the paper presents a multi-objective signal timing optimization model with vehicle volume and the non-motorized transport number as the inputs and traveler delay,stops and traffic capacity as the optimization objectives,and saturation degree is taken as restrictions.Furthermor... |
