基于路网的城域多路口交通模糊控制

Fuzzy Control of Multi-intersection Based on Urban Traffic Network

根据路网抽象出道路连接特点 ,考虑每个路口及其相邻路口的车流情况 ,提出一种多路口的模糊控制方案。该方案利用模糊规则库实时地控制信号灯的绿信比 ,协调和平衡各路口之间的车流。仿真结果表明 ,采用此方案可达到减少全局等候车辆总数的目标。

The traffic flow in one intersection is interacted by its surrounding intersections.A fuzzy control scheme of multi-intersection was proposed based on urban traffic road net taking into consideration of the vehicle information of each intersection and its surrounding intersections.In accordance with these information and fuzzy control rules coming from experts,the traffic lights′ green signal ratio is calculated and implemented in order to balance vehicle flows of multi-intersection and reduces the sum of waiting vehicles.The simulation model,steps and compared results with single intersection fuzzy control were given in the end of the paper.
