基于多智能体的信号交叉口微观仿真

交通系统是一个典型的多智能体系统(Multi-Agent System,MAS)。应用多智能体技术建立了信号交叉口微观仿真模型,给出了机动车Agent的三层结构,详细分析了机动车在信号交叉口中的基于期望间隙和期望速度的运动决策逻辑,探讨了机动车加速度模型。针对国内交通仿真软件缺少行人与非机动车模拟的不足,以元胞自动机模型为基础引入了行人及非机动车实体,使得仿真系统更具实用性。给出了该仿真系统的实现结果和结论。

Microscopic simulation of signalized intersection based on multi-agent

Traffic system is a typical Multi-Agent System.Microscopic simulation model of signalized intersection is built.The motor agent with three levels is represented.The movement decision logic of the motors in signalized intersection based on desire gap and desire speed is analyzed in detail.The acceleration model of motor is discussed.Some problems of current nation traffic simulation software such as the lack of pedestrian and non-motor model are presented.The pedestrian and non-motor entity is introduced based on the cellular automata model,which makes the simulation system more practical.Conclusions and simulation results of this traffic model are presented.
