城市单点交叉口信号灯模糊控制建模与仿真

从控制论的角度对城市单点交叉口信号灯的控制建立模糊控制模型,是通过模仿交通警察指挥疏导交通的决策过程而建模,设计详细的控制算法和模糊控制器,并利用Matlab和Simulink工具对模型进行仿真和分析。与定时信号控制方案相比,该模型可减少交叉口平均车辆延误,具有较好的控制效果。

Fuzzy Control Modeling and Simulation for Urban Traffic Lights at Single Intersection

The fuzzy control model for urban traffic lights at single intersection is built from the perspective of cybernetics. The modeling is designed by imitating the decision-making process of traffic policemen leading and unblocking traffic flow. The specific control algorithm and fuzzy controller are introduced in detail afterward. By using the Simulink tool in Matlab, the fuzzy control model is simulated and analyzed. Comparing with the timed traffic lights control solution, the fuzzy control model has better control effect whieh reduces vehicle average delay at the single intersection.
