该模糊控制算法对十二期三车道单十字路口交通灯进行智能控制，能很好地适应灵活运行的实时交通流。其过程可以描述为：首先，通过传感器接收所有车道的车辆数量，并规定车辆数量最多的阶段为最高优先级，而该阶段由前一阶段转向下一阶段，进入最高优先级。然后在当前等待队列长度和一般队列长度的模糊规则推理下，求出最佳的绿灯延迟时间。仿真结果表明，与传统的定时控制方法相比，模糊控制方法对车辆延迟时间的控制有了很大的改进。
The fuzzy control algorithm that carries on the intelligent control twelve phases three traffic lanes single crossroads traffic light, works well in the real-time traffic flow under flexible operation. The procedures can be described as below: first, the number of vehicles of all the lanes can be received through the sensor, and the phase with the largest number is stipulated to be highest priority, while the phase turns to the next one from the previous, it transfers into the highest priority. Then the best of the green light delay time can be figured out under the fuzzy rules reasoning on the current waiting formation length and general formation length. The simulation result indicates the fuzzy control method on vehicle delay time compared with the traditional timed control method is greatly improved.
