摘　　要：交叉口进口道困境区的存在增加了交叉口冲突的可能,设置合理的黄灯时间能减少陷入困境区的车辆,从而提高整个交叉口的交通安全。通过实际观测数据探讨不同驾驶行为参数与进口道黄灯启亮时车速和85%位车速之间的关系,通过模型回归不同速度下的驾驶行为参数,最终构建了动态困境区模型以及黄灯时间计算模型,为不同控制速度情况下的交叉口提供黄灯时间确定方法。The Dilemma Zone （DZ） located at signalized intersections increases the occurrence of traffic conflicts. Setting the reasonable yellow time can reduce the vehicle in the DZ, thereby impro- ving the traffic safety of the whole intersection. Through the actual data, it explores the relations between the parameters of different driving behavior and the speed and the 85% speed of the approach. Through regression model of parameters of different driving behavior under different speed of the approach, it con- structs a model of Dynamic Dilemma Zone and a model of yellow time, which offers a new way to design the yellow time.
