基于IC卡数据的武汉市轨道交通客流时空特征

Spatial-Temporal Characteristics of Urban Rail Transit Passenger Flow in Wuhan Based on IC Card Data

为了精准评估武汉市轨道交通运行现状、科学辅助编制轨道交通线网规划与建设规划、探寻运营组织中的潜在问题,通过对全市公共交通IC卡记录以及地理信息数据的融合与挖掘,从全网、走廊、断面等方面量化分析轨道交通发展历程和客流时空分布特征。在此基础上建立职住辨识模型,用于获取典型居住和就业区域的空间分布信息。基于此分析通勤群体的出行时间、距离、范围、方向不均衡性以及换乘等特征,并通过群体出行规律分析城市空间布局。最后对城市轨道交通发展提出建议:建立多样化运营模式,大力发展公共交通一体化换乘,注重轨道交通沿线土地开发利用和配套设施建设,加强各行政区协同发展和鼓励就近就业等。

To assess the urban rail transit operation in Wuhan and promote reasonable rail transit network planning and construction planning,as well as reveal potential problems of management,this paper reviews the development of Wuhan urban rail transit and analyzes spatial-temporal characteristics of passenger flow at network,corridor,and segment levels respectively using IC card records and geographic database.The paper develops a job-housing model to show the spatial distribution of residential communities and employment areas.Based on the travel characteristics such as travel time,distance,direction,roundabout during morning and afternoon peak hour,and transfer,the paper discusses the urban land use layout.Finally,the paper provides suggestions on urban rail transit development including diversifying operational modes,developing an integrated public transit system,promoting land use development along rail transit lines and facilities construction,and encouraging coordinated development among different regions.
