基于轨道刷卡数据的重庆轨道交通跨线客流测算及特征分析

Measurement and Characteristic Analysis of Chongqing’s Cross-line Passenger Flow of Rail Transit Based on Rail Card Data

在轨道交通互联互通场景下,受传统线路和跨线运营线路客流叠加影响,获取分线路客流成为难点。本文提出了一套基于轨道交通刷卡数据识别跨线车乘客、获取跨线客流分布的计算方法,并以重庆环线-四号线直快车为例进行了客流测算,通过现场抽样调查对测算结果进行了验证。结果显示,本方法可以有效获取跨线车客流及乘客出行分布。此外,本文还对重庆环线-四号线直快车客流分布特征进行了分析,为下一步轨道跨线运行线路设计提出了指导建议。

In the context of rail transit interconnection,it is difficult to obtain the passenger flow of separate lines due to the superimposition of passenger flow of traditional lines and cross-line operating lines.This paper proposes a set of calculation methods to identify cross-line passengers and obtain cross-line passenger flow distribution based on rail transit card data,and takes Chongqing Ring Line-Line 4 direct express as an example to calculate passenger flow,and verifies the calculation results through field sampling survey.The results show that this method can effectively obtain the passenger flow and passenger travel distribution of cross-line vehicles.In addition,this paper also analyzes the passenger flow distribution characteristics of Chongqing Ring Line-Line 4 direct express,and puts forward guidance and suggestions for the next track cross-line operation route design.
