摘要
货运道路车型构成复杂,不同车型的车速分布离散,造成追尾事故频发。在实地调查的基础上,结合一定的数理统计方法,对货运道路平面交叉口不同车型的车速分布特征进行分析,其结果可为交叉口的改善提供依据。
The structure of vehicle type on freight road is complicated. The speed of different types of vehicles is so discrete investigation, some mathematical features of different vehicles at that rear-end collisions take place frequently. On the basis of on-site statistics methods are adopted to analyze freight road plane intersection. The results can the speed distribution provide reference for the improvement of intersection.
