摘要
为掌握黄灯、绿闪和倒计时等不同信号过渡方式对驾驶行为选择的影响,通过对驾驶人黄灯期间交叉口驾驶行为决策过程及其因素的分析,采用现场视频摄录观测方法,对苏锡常地区的若干信号交叉口黄灯期间的机动车驾驶行为选择进行深度调查,对比了闯黄灯车辆行驶速度和初始位置,分析了前3辆机动车的驾驶行为选择。结果表明,信号交叉口采用绿闪和倒计时提示对驾驶行为选择影响较大,其闯黄灯行为发生率明显低于黄灯提示方式,但是倒计时提示会诱发机动车驾驶人加速通过交叉口并增加安全隐患。
In order to understand the effects of different types of transition signals （i. e. amber light, green flash and countdown device） on driving behavior choices at signalized intersection, this paper analyzed the decision-making process and factors of the driving behavior during amber light, and collected driving behavior data during yellow light in- terval at some signalized intersections in Suzhou City, Wuxi City, and Changzhou City by video record systems. Based on the investigation, the paper compared average speeds and initial positions of running amber light vehicles at intersections with different transition signals, and studied driving behavior choices of the first three vehicles from the stop line. The re- sults show that the use of green flash or countdown device much more deeply aIfected the drivers＂ behavior choices, and the rate of vehicle running amber light is significantly lower than that at signalized intersections with amber light. Howev- er, the countdown device tends to induce drivers to speed up through intersections and thus increases traffic safety risks.
