| 摘 要： | 通过对比闻红灯预测算法的性能,选择出用于区分车辆走、停行为的车辆轨迹特征参数.为实现对交叉口车辆闯红灯行为预测,根据闯红灯车辆为在红灯亮起后通过停止线的车辆这一定义,提出闯红灯预测算法的两个主要功能:估计车辆到达停止线的时刻;预测车辆到达停止线后的走、停行为.研究结果表明:在速度、加速度、行驶时间和车头时距4个物理量中...

| Abstract: | By comparing the performance of red-light-running(RLR) prediction algorithm,the vehicle trajectory characteristic parameters for distinguishing the go/stop behaviors were selected.In order to predict the RLR at signalized arterial intersections,based on the definition of RLR,which is a vehicle going through the stop bar after red light onset,two main functions of the RLR predicting algorithm were proposed.They are the estimator of the arrival time at the stop bar,and the predictor of the go/stop behavior af... |
