时变论域下红绿灯配时的模糊控制

针对交叉口日益拥堵，交通信号灯配时设置的不合理问题，提出一种基于时变论域的模糊控制方法，给出了交通信号灯的实时配时方案。该配时方法通过动态地调整信号周期和绿灯时长，以匹配多变的交通流状况，实现了实时控制。以长沙市某十字路口为例验证了该方案的有效性，结果表明：与定时信号配时方法相比，该配时方法更有效的缓解了交叉口交通拥堵状况，增强了路口通行能力，减少了车辆延误时间。

Fuzzy Control of Timing for Traffic Lights Based on Time-Varying Universe

A fuzzy control method based on time-varying universe is proposed to solve the problems of the increasing congestion for crossing and unreasonable traffic time.By the method,a real-time timing scheme is given.The scheme realized real-time control by improving the traffic signal cycle and the duration of green light and its effectiveness was verified by using a certain intersection of Changsha city.The result shows that compared with the fixed signal timing method,the scheme can effectively relieve the traffic congestion at intersections,enhance the traffic capacity of intersection,and reduce vehicles delay.
