摘要: 把城市交叉口的模糊控制方法应用于高速公路匝道控制,提出了用红灯延时来进行周期调节,根据下游占有 率的变化来设计模糊控制器的控制算法,对匝道控制的智能化进行了研究.最后,将算法在计算机上进行仿真计算, 并和常规的匝道控制方式进行比较,得出了这种控制算法优于一般控制算法的结论.

Abstract: The fuzzy control method of urban intersection was applied to expressway ramp control,and at the same time,the control algorithm which adjusted cycle by lengthening red time and designed fuzzy controller according to waving of occupancy rate was put forward.The intelligentizing of ramp control was studied.At the end,simulation of this fuzzy algorithm was calried out with PC,then the result was compared to that of the classic model of the ramp contro1.From that we make a conclusion that this algorithm is better than the common ones.

Key words: traffic engineering, expressway ramp, fuzzy control, occupancy rate, red time lengthening
