摘要
为分析车速、相位设置,以及倒计时与非倒计时的信控方式设置等因素对城市平面交叉口交通冲突的影响,选取西安市15个典型的平面交叉口进行实地调研,记录机动车与机动车之间的401条严重交通冲突数据作为分析样本,采用方差分析和t检验的方式剖析了城市平面交叉口多种严重交通冲突形式的致因及其显著性.分析结果表明,车辆通过城市平面交叉口的速度(p<0.01)、交叉口信号相位(p<0.01)和交叉口信控方式(p<0.05)等因素对追尾冲突、直行-左转冲突、交叉冲突等交通冲突(严重冲突)有显著的影响,而对直行-右转冲突和左转-右转冲突并没有显著的影响.
In order to analyze the influences of vehicle speed,phase setting and signal control mode of countdown and non-countdown for the traffic conflict on urban plane intersection,15 typical plane intersections in Xi＇an were selected for field investigation and 401 cases of serious traffic conflict data between vehicles had been recorded as the sample to analyze.The causes of serious traffic conflict on urban intersection and its significance had been analyzed by using the analysis of variance and t test.The results show that the speed of the vehicle through the intersection of urban plane intersection（p〈0.01）,intersection signal phase（p〈0.01）and intersection control mode（p〈0.05）have a significant impact on the serious conflicts of rear-end conflict,straight-conflict and intersection conflict,but have no significant impact on straight-right turn conflict and turn left-right turn conflict.
