基于元胞自动机和多主体相结合的交通仿真系统设计与实现

城市交通系统是典型的基于规则运行的复杂大系统，建立能描述实际交通系统一般特性的交通流模型，寻找交通流的基本规律，揭示交通拥堵产生的机理，实现人、车、路与生态环境之间的和谐统一，一直以来都是该领域的热门主题．论文基于元胞自动机和多主体技术，应用Matlab编程语言设计并实现集交通道路（舍交通规则与信号灯）、机动车以及行人于一体的交通流仿真系统．在4种交通规则下，分别考察了机动车和行人闯红灯行为对交叉路口通行质量的影响．其结果有助于揭示交通拥堵产生的内在机理，并为自动疏导交通提供参考措施．

Design and Actualization of a Traffic Simulation System Based on CA and MAS

The metropolitan traffic system is one of complex large-scale systems running on rules. Theory of traffic flow aims at creating models that well characterize the real traffic phenomena, finding underlying traffic flow rules, disclosing traffic jam mechanisms and then regulating the existing system to realize harmony between humans, vehicles, roads and the ecosystem. In this paper, a kind of traffic simulation system which integrates the roads （including traffic rules and signals）, vehicles and pedestrians is designed and realized via Matlab based on Cellular Automata and Multi-agent System theory. The impact of red-lights running by vehicles and pedestrians on the traffic quality at cross-roads is investigated respectively under four traffic rules. This research helps to identify the underlying mechanism of traffic jams at cross-roads and provides feasible measures for automatic channeling traffic.
