| 摘 要： | 通过计算机仿真软件ARENA模拟双向两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，超越车与对向车辆间的最短时间距离确定。一共确定了六个风险等级，用于评价不同设计时速下的各种PSD长度的风险。利用此方法可以很直接的评价超车视距设计的优劣。

| Abstract: | A unique microscopic simulation using the ARENA software for replicating overtaking maneuvers on two-way,two-lane roads is devised,with the weighted risk index obtained.The risk index is mainly based on the values of the clearance and time between the overtaking and the opposing vehicles at the end of the overtaking maneuver.Six levels of risk are identified,which are used to assess the risks of various PSD lengths for specific design speed.Both the merits and demerits of PSD in the design can be directly a... |
