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.
The non-linear mapping model was used to study the traffic problems at the T-junction, and the influence of bus stop, traffic light cycle, green ratio and left-right turning of the vehicle on the traffic flow was systematically analyzed by using the point average flow index.The numerical simulation results show that, The interaction between the signal light and the bus station can easily lead to the phenomenon of traffic flow. There is a certain relationship between the traffic flow and the signal cycle, the ratio of green signal to the bus station and the location of the bus stop.
