| 摘 要： | 在设置路侧公交专用道的交叉口处,可通过划定交织区的方式允许右转车辆借用一定长度的公交专用道通行.合理规划公交车与右转车的交织区长度有利于提高借道右转的通行效率,减少在交织区前的排队车辆数从而降低道路混乱程度,保障公交车的专用路权.本文分析了公交站点影响下的公交车车头时距分布,建立了右转车穿越交织区长度计算模型,并结合实际调查数据进行了算例分析和模型验证.研究成果可为公交优先条件下的交叉口空间优化设计提供理论参考.

| Abstract: | Right-turning vehicles are allowed to use the road-side transit-lane when they are at the entering approach. It is necessary to optimize the weaving length to improve the efficiency of right-turning flow and lower the impact on buses turning along the transit lane. Distribution of bus turn headway is firstly analyzed concerning about stop time. Then a working model is developed to determine the weaving length for rightturning vehicles. At last, a case study is conducted using actual data. The results provide reference for channelization of entering approach under bus priority policy. |
