信号灯和公交车站对T形路口交通流的影响研究

采用非线性映射模型研究T形路口的交通问题，利用点平均流量指标系统地分析了公交车站、信号灯周期、绿信比、车辆左右转弯等因素对路径交通流量的影响.数值模拟结果表明，信号灯和公交车站之间的相互影响容易导致交通流的串现象，不同路径上的流量与信号灯周期、绿信比和公交车站位置之间存在一定的关系. 关键词： 交通流 非线性映射模型 信号控制 串

Influences of signal light and bus-stop position on T-road junction traffic

In this paper，we apply a nonlinear map model to investigate the influences of signal light and position of bus-stop on the traffic at a T junction. The dependence of point-based average flow of routes on bus-stop position，signal light cycle and split as well as vehicle swerve are numerically analyzed. Simulation results show that the interaction between bus-stop and signal light generates traffic clustering easily，and there exist relationships between signal light cycle，split，bus-stop position and the route flows.
