受公交停靠站影响的道路通行能力分析

Analysis of Road Capacity Affected by Bus Stops

公交停靠站是影响道路路段通行能力的重要因素,传统的通行能力计算方法忽略了这一因素,使得计算结果与实际有一定差距。针对这一不足,提出改进思路。根据公交停靠站对道路通行能力影响的不同,将其分为港湾式和非港湾式两种类型进行分析,利用排队论和间隙理论得到相应的修正系数,最后以工业区规划作为实例项目进行通行能力验算,为城市道路规划和服务水平的确定提供依据。

For found that the effect of bus stop on capacity was ignored in the computing process, which would cause error. To resolve this problem, the new ideas for improvements were brought. By means of analyzing the operational features of traffic flow at different groups of bus stop, two types of bus stop were categorized, based on queue theory and critical gap theory, the coefficients were gained. The determination of urban road planning and service levels were provided with analysis of traffic flow characteristics based on an industry zone.
