摘　　要：交通信号控制系统是城市交通的基本组成。文章针对交通路口信号控制中的时间分配算法进行研究。根据交通路口抽象模型,综合多种路口流量因素,引入了综合流量指标来对交通流量进行量化描述。并且以该综合指标为中心设计了具备自适应能力的信号控制算法。实现了能够依据交通流量状况进行路口时间调整的交通信号控制系统模型。通过NetLogo平台进行仿真实验,证明该系统模型可以很好的适应路口交通流量变化和差异,一定程度上可以作到对交通压力的缓解。Traffic light control system is the basic element of modern city traffic.This paper focuses on an algorithm of time control in the traffic signal control system.Based on the abstract model of intersection,the paper integrates multi-factors of traffic flow,and introduces a new evaluation to describe the traffic flow.And further more,it designs an adaptable signal control algorithm based on this integrateed evaluation.A traffic signal control system model is realized which could change signal according to traffic flow of intersection.According to the simulation experiment on NetLogo platform,it validates that the model could be adapted to the changes and differences of flow in the intersection,and reduce traffic pressures to some extent.
