交通流元胞自动机模型综述

随着交通流模拟的需要及智能交通系统的发展,出现了基于元胞自动机理论的交通流模型。交通流元胞自动机模型由一系列车辆运动应遵守的运动规则和交通规则组成,并且包含驾驶行为、外界干扰等随机变化规则。文章介绍了交通流元胞自动机模型的产生与发展,总结和评述了国内外各种元胞自动机模型,并对元胞自动机模型的发展提出展望。

Survey of Cellular Automata Model of Traffic Flow

With the increasing demand of traffic flow simulation and the development of ITS research,the traffic flow model based on cellular automata has been developed.Cellular automata model of traffic flow incorporates a series of vehicle movement rules and traffic regulations.Meanwhile,the model works under some stochastic rules taking into consideration of drivers' behaviors and ambient interferences.This paper introduces the establishment and development of cellular automata model of traffic flow,summarizes and comments on different kinds of typical cellular automata models of traffic flow,and furthermore,presents a new perspective for further study of the model.
