【摘要】：为提高信号交叉口的交通安全管理水平,研究驾驶员换道行为影响因素,确定各因素影响下的换道风险率,选取可能影响变道行为的潜在变量,构建交叉口换道行为的Cox风险分析模型,并以武汉市3个交叉口调查数据为例进行实例分析。结果表明:10个因素对进口道车辆换道有显著影响,其中,车辆与目标车道前方车辆的车头间距、与目标车道后方车辆的车头间距、所在车道与目标车道车辆密度差和可供变道选择的目标车道数是危险因素;车辆与所在车道前方车辆的车头间距、车辆距停车线距离、行驶速度和所在车道相位的绿信比是保护因素。车辆处于信号灯倒计时的变道风险率高于其他时段;出租车的变道风险率高于其他车辆。
[Abstract]:In order to improve the traffic safety management level of signalized intersections, this paper studies the influencing factors of drivers' changing traffic behavior, determines the risk rate of changing lanes under the influence of various factors, and selects the potential variables that may affect the changing traffic path behavior. The Cox risk analysis model of intersections is constructed, and the investigation data of three intersections in Wuhan are taken as an example. The results show that 10 factors have a significant effect on the change of lane, including the headspace between the vehicle and the vehicle in front of the target lane, and the distance between the front of the vehicle and the vehicle in the rear of the target lane. The difference of vehicle density between the lane and the target lane and the number of the target lanes which can be chosen by the changing lane are the risk factors. The distance between the vehicle and the vehicle in front of the lane, the distance between the vehicle and the parking line, the green signal ratio between the driving speed and the phase of the lane are the protective factors. The change risk rate of vehicles in signal lights countdown is higher than that in other periods, and that of taxis is higher than that of other vehicles.
