城市交通单交叉口两级模糊控制器的设计

针对交叉口信号灯模糊控制器的特点,采用分级的模糊控制器,有效地减少了控制规则数,使控制规则的选取更加容易。同时,为了使设计的控制器更加符合实际交通状况,设计的控制器不仅优化相序,而且优化绿灯配时。通过仿真证明,该系统能有效地提高交叉口的通行能力,减少车辆延误。

Design of Urban Traffic Lights Based on Two-stage Fuzzy Control

Against fuzzy controller＇s feature in consideration of signal lights at cross path,a classification fuzzy controller was adopted to reduce the number of fuzzy rules effectively,which made the selection of fuzzy rules more easier than ever before.And in order to design the controller to be more in line with the actual traffic situation,the designed controller not only optimized sequence,but also optimized the time allocation of green light.The simulation results expatiate this system highlights traffic capacity at cross path effectively and reduces automobile＇s delay.
