基于多智能体元胞自动机的城市交叉口控制方法

为提高对现有交通资源的利用和提供更加有效的交通管理方法,针对交通流中各个体的不同特性,阐述一种城市交叉口基于多智能体和元胞自动机的智能控制系统的框架结构。系统采用元胞自动机建立道路模型,并对原有的单元胞单容量这种不符合实际情况的设置进行了改进,采用单一元胞中可容纳多个不同类型车辆;最后探讨了系统中各个交通智能体协调合作关系,为基于多智能体、元胞自动机的城市交叉口控制系统的最终实现提供了理论指导和方法依据。

Control Method for Urban Intersection Based on Multi-Agent and Cellular Automation

To improve the use of the finite resources and modify the measure we used in traffic control ,according to different behaviors of by different individuals in traffic flow, a frame structure of intelligent traffic control system based on multi-agent and cellular automation was analysed in the paper. This paper used the cellular automation to build the road net, meanwhile, the traditional, unsuitable way used in cellular automation was changed to a new rule that one cell could hold several different types of vehicles with consideration of cell＇s capacity. In the end, it discussed the cooperative relationship of those agents in the control system, and provided theoretical guidance and methodical gist for the ultimate realization of the urban traffic control system based on muhi-agent and cellular automation.
