分组拥塞控制在城市交通控制中的应用

Urban traffic control based on jam control of data communication

针对交通拥塞这一困扰城市的难题,根据城市道路交通网中交通流与数据通信网中分组流相类似的特点,利用数据通信网中解决分组拥塞的理论,分析了城市交通拥塞的原因,并提出了解决思路。给出了分布式、集中式两种智能化的交通拥塞反馈控制系统模型,重点论述了分布式交通拥塞控制系统模型中最重要的组成部件——交通控制器的主要功能及其流量控制算法、汽车行进路线算法。认为该系统模型能实现城市智能交通控制,有效解决城市交通拥塞问题。

According to the features of urban traffic flow,the jam control method of data communication was applied to urban traffic control to resolve its traffic congestion.Based on this method,the reason of traffic congestion was discussed,a model for traffic control and its algorithm were presented.The results show that this model can realize the control of urban traffic flow,and it is an effective method for resolving traffic congestion.
