基于空间智能体的交通信号灯模型构建

The Construction of Traffic Signal Lamp Model Based on Spatial Intelligent Agent

在我国交通问题日益严峻的背景下,交通信号灯在疏导车流方面的意义愈发重大。采用空间多智能体建模方法,使用Netlogo多智能体可编程建模平台,对交通信号灯模型进行构建。通过车辆智能体与其他车辆智能体、信号灯智能体以及瓦片交互实现对车辆智能体控制。将车辆数量和不同方向的信号灯时长作为模型输入参数,设定三种方案进行动态模拟,监测该模型在一定时长内所有车辆总等待时长。通过调整输入参数以及数据统计,对不同信号灯配时方案进行分析,为交通信号灯配时方案的制定提供一定参考。

Under the background of the increasingly serious traffic problems in China,traffic signal lamp is becoming more and more important in guiding traffic flow.So multi-intelligent agent modeling method to construct a traffic signal lamp model by using the multi-intelligent agent programmable modeling platform of Netlogo is applied here.The vehicle intelligent agent is controlled by the interaction of vehicle intelligent agents with other vehicle intelligent agents,signal light intelligent agents,and patches intelligent agents.The number of vehicles and the time of signal lights in different directions are set as the input parameters of the constructed model.Simulated and monitored the total waiting time for all vehicles in a certain period by setting three schemes.Different signal schemes can be analyzed by the adjustment of input parameters and the statistics of output results,and this study can provide a reference to formulate signal schemes.
