摘要: 针对绿灯末期小车跟驰大型车辆的闯红灯现象,位研究信号灯位置不合理是否会引起被迫性的误闯红灯情况,笔者以南京市某交叉口车流数据为依据,通过单因素方差分析得出视线遮挡对后车车速及车头时距分布有显著性影响。并以小车能及时发现信号灯且安全制动为前提,通过车辆与信号灯之间的视线几何关系分析,探讨了基于合理跟驰距离的信号灯设置高度设置范围,构建了2种不误闯红灯的车辆跟驰条件模型。研究结果表明:将信号灯移动到进口道停车线时,可以消除大车对后方跟驰小车视线遮挡的不良影响。

Abstract: Aiming at the phenomenon of running the red light caused by small cars following large vehicles at the end of the green light period, whether the unreasonable position of the signal light will cause the forced red light running by mistake was studied. Based on the traffic flow data of an intersection in Nanjing, the conclusion that sight occlusion may have a significant impact on the distribution of speed and headway of the following vehicles was obtained by the single factor analysis of variance. Based on the premise that the car can find the signal light in time and brake safely, the geometric relationship of the sight between the vehicle and the signal lamp was analyzed. The range of setting height of signal lamp based on the reasonable following distance was discussed, and two kinds of car-following condition models were built, which could protect drivers from running the red light. The research results show that the adverse effect of the large vehicle on the sight blocking of the following car can be eliminated, when the signal lamp is moved to the parking line of the entrance lane.

Key words: traffic engineering, signalized intersection, the position of the signal lamp, car following, headway
