在道路交叉口正确设置左转车辆的黄色信号灯和全红(所有方向信号灯均为红色,在必要时设置)的时间长度,能够提高交叉口的效率和安全.本文分析了影响2种信号周期设置的各种因素,以及2种信号时间的计算机理,在计算模型中引入了更多的影响因素,使得模型更加合理和符合交叉口的实际情况.同时,对于一些难以量化的人为因素,例如驾驶员的驾驶特性,引入了3个参数,并且根据大量实验数据,给出了这些参数在各种交叉口环境下的参考值.经过这些研究,黄色信号灯和全红时长的计算模型得到了改进,提高了交叉口交通的通行效率和安全.
The correct length and length of the left and right red (all directional lights are red, set if necessary) at the road intersection can improve the efficiency and safety of the intersection.This paper analyzes the impact of two signal cycle settings , And the calculation mechanism of two kinds of signal time, more influencing factors are introduced into the calculation model to make the model more reasonable and accord with the actual situation of the intersection.At the same time, for some difficult to quantify human factors such as driving The driving characteristics of the driver are introduced into three parameters and given the reference values of these parameters in various intersection environments based on a large number of experimental data.After these studies the calculation models of the yellow signal and the full red duration have been improved, Improve traffic efficiency and safety at intersections.
