摘　　要：通过分析两难区车流量与车速的关系,车速与两难区黄灯时间的关系,结合实际交叉口车流量,提出基于模糊控制的动态两难区黄灯时间控制策略,建立黄灯时间模糊控制规则表和响应表。最后通过不同交叉口车流量的调查情况表对VISSIM仿真路网中的车辆类别、期望速度、加减速度、车流量进行设置,并根据交叉口固定信号灯相位图、配时表和模糊控制响应表对VISSIM路网中的信号灯进行更改,仿真得出车辆在通过有模糊控制黄灯时间和黄灯时间固定配时的交叉口时,其前者陷入两难区的概率远少于后者陷入两难区的概率。By analyzing the dilemma zone and dilemma zone on the relationship between the speed and the dilemma zone,speed and yellow light timing,based on fuzzy control dynamic dilemma zone yellow light time control strategy was proposed,yellow light time single input single output fuzzy control rule table was set up,and according to the actual traffic survey,yellow light time fuzzy control response table was built. Finally VISSIM simulation network of vehicle model,vehicle type,expectations set speed,add and subtract speed,traffic should be set up by each period by the variety of various models of cars that actual intersection,according to the different actual sections of intersection fixed signal phase diagram,timing table and the yellow light time fuzzy control response table dynamic dilemma zone,VISSIM lights for correction of road network should be rectified,the simulation experimented that on the vehicle in the intersection of fuzzy control by a yellow light time or yellow light time according to the intersection of fixed timing,the probability of the former is far less than the latter in a dilemma.
