摘要
分析了现有的车头时距分布模型 基于对我国大量的双车道公路上运行车辆车头时距分布模式的调查 ,提出了改进的M 3型车头时距分布模型 ,推导出双车道公路无信号交叉口处当主车道车流车头时距服从改进的M 3型分布时次车道车流通行能力计算公式 ,得出了整个交叉口通行能力随主车道车流量的关系 。
The existing headway model is discussed. Based on the headway data research of the two lane highway in our country, an improved M3 headway distribution is presented. When the headway of the major streams of the unsignalized intersection fit the improved M3 headway distribution, the capacity formula of the minor stream is developed. The relationship of the capacity of intersections with the major vehicle flow is educed,thus providing the basis for intersection appraisal and management.
