| 摘 要： | 利用元胞自动机方法建立了一个具有三个进车道的信号灯控制的T形交叉口模型。在以前的无信号灯控制的模型中,一些进车道的车辆在交叉口只有一个行驶方向,而在本文模型中采用更为实际的两个行驶方向,并采用具有固定周期的三相信号灯来控制交叉口的车辆冲突。通过数值模拟给出了本文模型的相图和系统的总流量,并与无信号灯模型结果进行了比较。

| Abstract: | Traffic flow at a signal controlled T-shaped intersection where there are three input directions of vehicles was investigated by the cellular automata model.Because in the previous models some vehicles at intersection only have one steering way,a more realistic model which vehicles on each input lane have two steering directions was introduced.The three phase traffic signal with fixed period was used to control the conflicts of vehicles.The phase diagram and capacity of the system were investigated and comp... |
