摘要 通过建立黄灯启亮时驾驶员的行为决策模型,分析黄灯启亮时的驾驶行为及其影响因素.利用视频观测的方法,采集分析了黄灯启亮时的车辆行驶数据,并建立了黄灯启亮时的驾驶行为决策模型,通过模型分析了影响黄灯启亮时驾驶行为的关键因素.结果显示,黄灯启亮时车辆到停车线的距离、车速,以及有无前后车是影响驾驶行为的显著变量:有前车的情况下,驾驶员更倾向于选择通过交叉口;无后车时,即车辆位于排队队尾时,驾驶员加速时加速度的绝对值更大,减速时加速度的绝对值更小.驾驶员在黄灯启亮时表现出的上述行为特征十分危险,需要制定有效措施加以控制,以减少交叉口黄灯期间的交通事故. Driving behaviors at signalized intersections at the on-set of yellow light are crucial to traffic safety and traffic efficiency.A decision-making model is established in order to analyze the characteristics and influencing factors of driving behaviors at the on-set of yellow light.The study examines the driver s decision-making process and establishes a driving decision-making model,then influential factors analysis are made using vehicle driving state parameters collected by video observation.The results indicate that distance between the vehicle and the stop bar,the vehicle speed and the presence and absence of leading and rear vehicles are key factors to driving behaviors at the on-set of yellow light.With a leading vehicle,drivers are more likely to enter the intersection;drivers tend to accelerate more and decelerate less when the vehicle is at the end of the queue.The above behavioral characteristics of drivers pose a serious threat to traffic safety and need further study to find effective solutions.
