城市信号交叉路口黄灯信号模型研究

Study of yellow light signal model at intersection in a city

主要研究了计算黄灯闪烁持续时间的方法和有关黄灯时间所造成困境区域的内容。通过运用车辆的动态特点的真实评估,研究当驾驶员面对黄灯信号时可能的选择,并结合困境区域的原因分析与数学描述,提出黄灯时间的计算模型。计算模型重点在于分析困境区域对于驾驶员的影响,并借由分析结果给出合理的黄灯时间分配安排。最后,对设置黄灯信号及现有交通条例的制定提出一定建议。

This article examines mainly the method for calculating the duration of the yellow light flashing and the contents of dilemma zone caused by yellow light time. Based on the realistic assessment with dynamic characteristics of vehicles, any possible option was studied when the drivers are faced with the yellow light signal, with presentation of calculation model for yellow light time. The model, in combination with analysis on causes of dilemma zone, focuses on examining the effect of the zone on the drivers, and gives the reasonable schedule arrangement for yellow light time by using the analysis results. Finally, it put forward some suggestions for setting out the yellow light signals and working out the current traffic regulations.
