基于环形线圈检测器的复杂交叉路口多相位模糊控制

Multi-Phase and Fuzzy Control of Complicated Intersection Based on Loop Detector

利用环形线圈检测器获得复杂交叉路口的实时交通数据,设计了一个三路交叉复杂路口交通信号灯的多相位模糊控制。通过多相位设计对交叉口的复杂交通流进行了规划组织,模糊控制策略可以对绿灯配时进行适当的调整以适应交通状况的实时变化。仿真结果表明,多相位模糊控制效果在减少车辆延误时间指标上优于传统的定时控制。

Based on the real-time traffic data obtained by loop detectors, a multi-phase and fuzzy signal control is designed for a complicated intersection crossed of three roads. The multi-phase design is to organize the complicated traffic, and the fuzzy control strategy can adaptively adjust the signal timing to adapt the traffic change in the complicated intersection. The simulation test shows that the multi-phase and fuzzy control outperforms the traditional fixed time control in reducing the vehicle time delay.
