改进点格自动机交通网络模型及交通系统自组织现象的研究

Modified Cellular Automata Traffic Network Model and Study on the Self organization of the Traffic Systems

基于点格自动机的原理，提出一种比较切合实际的改进点格自动机交通网络模型。该模型把交通网络分为“道路”和“路口”。用队列来模拟“车流”，车辆密度分为三档。在此模型基础上，研究了不同情况下交通系统中的自组织现象。理论上分析了自组织形成的动态过程。

Based on the principles of the cellular automata, a new improved cellular automata traffic network model which is more near the realistic traffic patterns is presented in this paper. In the model, the traffic network is divided into 'sections of roads' and 'intersections'.The traffic flows are simulated with 'teams' and the vehicle density is divided into three levels.With this model, we study the self organization phenomena of the traffic system under different situations and analyze the dynamic process of the formation of the self organization patterns.Computer simulation is also presented.
