摘要
文章从理论上推导了交通需求与道路宽度、有效通行时间比的相对关系,进而推导出一个流向上的车道数量的计算公式,并针对典型的十字交叉口和路段情况,详细讨论了交叉口进出口道和路段上车道数量计算公式。最后,对一个算例进行了验证和总结。
The paper theoretically deduces the relative relationship of the volume, the required effective passage time ratio, and the required road width of a traffic movement. Then, it establishes the model of the number of the lanes in a flow direction, and gives the formulae of the number of the approach lanes, the number of the exit lanes of the typical right-angle intersection, and the lane number of road sections. Finally, the paper validates the model by an example.
