根据车站售票量统计地铁各种客流指标,是交通管理部门的迫切要求.地铁客流分析可以辅助地铁运营企业制定运营计划、进行地铁改扩建项目的可行性分析等决策行为.针对地铁环线,提出了进行客流分析时用于计算方向不均衡系数的两种模型,并给出了理论证明.我们采用这两种模型进行某大城市地铁的实际客流分析,取得了满意效果. According to the station ticket sales statistics of various passenger traffic indicators of the subway is an urgent requirement of the traffic management department.The subway passenger flow analysis can assist the subway operators to develop operating plans and carry out the feasibility analysis of the subway expansion project decision behavior.For the subway ring line Two models for calculating unbalanced coefficients in passenger flow analysis are given and theoretical proofs are given.We use these two models to analyze the actual passenger flow in metro of a metropolitan area and achieve satisfactory results.
