摘要
基于广州地铁交通流的始发地(Origin)—目的地(Destination)(OD分析),运用出行成本(距离/时间)、集中出行距离区间等指标对地铁站点交通流特征及居民地铁出行的人群分异进行刻画。结果表明:1)地铁站点随出行距离增加的乘客累积比例呈“S”型曲线变化,广州地铁站点的平均出行成本约为14.04 km(20.48 min),并由中心向外逐层增加约4 km(5 min)和13 km(10 min),周末平均出行成本略高于工作日。2)广州地铁出行的集中距离区间为8.55~26.61 km,在该出行距离范围内的乘客量占总数的71.88%;周末出行集中距离区间宽度变窄,但乘客量的集中比例却有所下降。3)社会弱势群体如女性、老年人、固定上下班的大学以上学历人群、办事人员、商服人员等是地铁潜在客流的主要构成群体;不同人群的地铁平均出行距离出现分化,其中出行需求小、出行能力偏弱的群体平均出行距离较短,出行需求大的群体平均出行距离普遍较长;除个别人群外站点集中出行距离区间相对差异不大。
Metro railway is emerging as the optimal choice for residents'daily travel in many metropolitan areas in China,which profoundly affects the spatial-temporal characteristics of the travel mode of residents.Studying the spatio-temporal characteristics of metro traffic flow is of great practical significance for optimizing metro traffic layout and relieving urban traffic pressure.Reported studies have afforded significant achievements in the spatial-temporal characteristics of metro traffic flow;however,there are very few studies on the overall perspective of the station network,and most of them fail to further analyze population differences in using metro systems.In view of these gaps in the existing research,this study has two main objectives:1)to describe the characteristics of metro traffic from the overall perspective of metro station network,with parameters of traffic flows within the station network,average travel distance(time),and their aggregation features;and 2)to analyze the differentiation of population groups near metro stations for understanding population differences in metro traffic flow.The Origin-Destination(OD)analysis method was used to calculate traffic flow characteristics between different metro stations,including the average travel cost(distance/time)and travel aggregation distance interval.Our results lead to the following inferences.1)The cumulative proportion of passengers in metro stations along with travel distance show an"S"curve function feature,the average travel cost of metro stations in Guangzhou is approximately 14.04 km(20.48 min),and increase by~4 km(~5 min)and~13 km(~10 min)from the central area to the inner and outer suburbs.The average weekend travel costs are slightly higher than that of weekdays:the average travel cost on weekend ranged from 0.03 km(0.06 min)less in the central area to 0.32 km(0.49 min)and 0.64 km(0.77 min)more in the inner and outer suburbs,respectively.Three types of metro stations—those serving external transportation,business offices,and public units�
