【摘要】：为了解信号交叉口处绿灯充足时段交通违法监控是否对机动车车速及驾驶人驾驶行为决策产生影响,运用录像法,分别对经过青岛市黄岛区2类4个信号交叉口绿灯充足时段的机动车进行调查。采集了车辆经过交叉口的车速、加速度、所在车道等具体数据,对经过2类信号交叉口的车速及行为决策进行对比分析;并运用logistic回归模型建立信号交叉口驾驶行为决策模型。结果表明在绿灯充足时段,在装有交通违法监控的信号交叉口,进入交叉口前的机动车车速较低,且离散程度较小;进入装有监控的信号交叉口时,驾驶人采取匀速行为决策的比例比无监控情况高22.78%;较减速行为决策相比,加速和匀速行为决策与交通违法监控、车速及所在车道有关。
[Abstract]:In order to understand whether traffic illegal monitoring at signalized intersections during sufficient green time has an impact on vehicle speed and driver's driving behavior decision, video recording method is used. An investigation was carried out on vehicles passing through 2 kinds of 4 signalized intersections in sufficient green time in Huangdao District of Qingdao City. The speed, acceleration and lane data of vehicles passing through the intersection are collected, the speed and behavior decision of the signalized intersection are compared and analyzed, and the decision model of driving behavior of signalized intersection is established by using logistic regression model. The results show that at the signalized intersection with traffic illegal monitoring, the speed of the vehicle before entering the intersection is lower and the degree of dispersion is small, and when entering the signalized intersection with monitoring, the results show that when the traffic light is sufficient, the speed of the vehicle is low and the degree of dispersion is small. Compared with the decision of decelerating behavior, the decision of acceleration and uniform speed is related to traffic illegal monitoring, speed and lane.
