【摘要】 介绍了一种基于模糊控制理论的十字路口模糊交通控制器的设计。针对当前城市交通系统中的被控对象具有较大的随机性和偶然性,引入了不需要建立精确数学模型的模糊控制。首先根据进道口的检测器测得车量的多少,由第1级模糊控制器确定下一执行相位;然后根据当前相位车量的多少以及下一相位车辆的多少由第2级模糊控制器确定当前执行相位的绿灯延长时间。较好地解决了交通流量不均衡、不稳定所带来的车辆延误等问题,提高了道路的通行能力。更多还原

【Abstract】 This paper introduces a crossroad fuzzy traffic controller based on the fuzzy control theory.This design uses fuzzy control theory which doesn’t require exact mathematical model because of the randomness of the controlled objects in the current city traffic control system.On the basis of the measured traffic data,the first fuzzy controller determines the next phase to be executed;then the second fuzzy controller calculates the increased green time based on the traffic.The kind of controller settles the problem of uneveness of the vehicles better and improves the traffic throughput of the road.更多还原
