摘要
当右转车辆与行人过街处于同一个相位时,假如与右转车道相邻的车道上停着一辆大、中型车辆时,就会同时阻碍右转车辆和行人的视距,从而影响右转车辆的可接受间隙行为。引用随机威布尔分布函数,对可接受间隙概率参数进行估算。并利用实际数据分析了在有无视距遮挡的情况下右转车辆的可接受间隙行为的变化。结果显示,在视距受阻的情况下,右转车辆更倾向于接受较小的间隙而拒绝较大的间隙,这大大增加了右转车辆与行人之间的潜在冲突。
When the right-turn vehicles shared the same phase with pedestrians at intersect divided lanes, the stopped bus or medium-size vehicle which closed to the right-turn vehicles block the view both of right-turn drivers and pedestrians from the far-side of crosswalk. This aims at analyzing the changes of lag/gap acceptance behavior with and without considering obstruction. In addition, the headway of following right-turn vehicles was also analyzed. Cumt Weibull distribution function was used to estimate parameters of lag/gap acceptance probabi The result showed that right ＊urn driv,：rs.＊_ended to acceEt a smaller lag/gap and rejected a lage gap with restricted sight. Owing to the acceptance of smaller lag/gap with sight problem, it lead to more potential conflicts between right-turn vehicles and pedestrians.
