| 摘 要： | 通过计算机仿真软件ARENA模拟双向2车道路段上不同的超车视距长度下的超车行为，并建立风险指标。风险指标主要根据超车动作结束时，超越车与对向车辆问的最短时间距离。共确定了6个风险等级，用于评价不同设计时速下的各种超车视距长度的风险。

| Abstract: | The paper simulats passing behaviors under different lengths of PSD on two-lane two-way road by using the ARENA software,and establishes weighted risk index.The risk index is mainly based on the value of the clearance time between the passing and the opposing vehicles at the end of the passing maneuver.Six levels of risk are identified,which is used to assess the risk of various PSD lengths for various design speed. |
