摘要
平确定均站间距是城市轨道交通规划与设计的重要内容。以乘客出行过程产生机理为基础,引入决策树思想,建立基于乘客出行总成本最小的多方式组合最优模型,通过系统临界值的计算确定城市轨道交通平均站间距全局最优值。根据实例分析,说明该模型在确定城市轨道交通平均站间距中的应用。
The average station spacing is one important part in the planning and design of urban rail transit. Based on the analysis of generation mechanism in passenger travel process and the method of decision tree, the authors establish the optimal model with multi-mode combination based on minimum passenger total travel cost. It determines the optimal value of average station spacing in urban mass transit through the system critical value. In the end, the application of this model in average station spacing of urban mass transit is illuminated through a case study.
