单交叉口交通灯信号模糊控制及其仿真

本文采用模糊控制算法对四相位三车道单交叉口的交通灯进行控制。首先通过离线计算机得到绿灯延时的模糊控制查询表,根据当前等待队列长与通行队列长查表和到绿灯延时。通过使用同一随机种子产生随机数对该方法与传统定时控制方法进行仿真,仿真结果表明模糊控制方法在车辆延误时间上较之传统定时控制方法大为改善。

The fuzzy algorithm control for Single road intersection traffic light and its simulation

This paper uses the fuzzy control algorithm carries on the control to four phases three traffic lanes single road intersections traffic light. First obtains the green light time delay through the off- line computer the fuzzy control questionnaire. Is long and the general formation according to the current waiting formation long looks up the table and to the green light time delay. Has the ran- dom number through the use identical stochastic seed carries on the simulation to this method and the traditional timed control method, The simulation result indicates the fuzzy control method delays in the time in the vehicles compared with the traditional timed control method greatly is the improvement.
