城市轨道交通站间距优化研究

通过对受站间距影响的城市轨道交通相关指标分析,学习并借鉴国内外城市轨道交通站间距优化方面的成功经验及研究方法,以实际数据作为基础,首先对客流分布和乘客出行时间这两个影响因素进行分析,通过分析认为城市轨道客流随着乘坐距离的变化存在着一个先增后减的函数变化;根据对客流分布以及乘客出行时间的分析,将乘客出行时间成本转化成经济效益指标,将票价收入标准与客流分布进行结合得到地铁票价收入的经济效益;之后结合乘客出行时间的经济效益和票价收入的经济效益按照总收益最大化建立城市轨道交通站间距优化模型,并实施优化计算,碍到理论上的最优站间距.

Study on Optimal Spacing of Rail Transit Station

Based on related indicator analysis of station distance effect for city rail transportation,the factors of passenger flow distribution travel time are analyzed,it is found that the city rail passenger flow with a variation in the distance there is a first increase and then decrease the function change.Based on the passenger flow distribution and analysis of passenger travel time,the passenger travel time is put into economic benefit index,and the ticket income standards and the passenger flow distribution are combined to obtain the economic benefits of the subway fare revenue.Combining the passenger travel time with the economic benefits of the ticket revenue economic benefit,a city rail transit station spacing optimization model is built according to the maximum gross income,and implementation of the optimization calculation is conducfed to obtain the optimal average station spacing.
