基于共享单车接驳的城市轨道交通站点可达性评估方法

Research on Accessibility Evaluation Method for Urban Rail Transit Station Based on Shared Bicycle Connection

[目的]共享单车是一种有效的城市轨道交通(以下简称“城轨”)站点接驳方式,有必要建立基于共享单车接驳的城轨站点可达性测度模型,并对其进行评估。[方法]基于南京共享单车出行数据与城轨站点数据,对各站点的共享单车骑行时长、骑行距离及接驳量进行了统计,选取骑行距离作为城轨站点可达性评价指标。对城轨站点可达性测度所需的可动性、易达性、通达性,以及站点规模影响因子等指标进行了计算,构建了基于共享单车接驳的城轨站点可达性测度模型。对南京市城轨站点进行了聚类分析,并对该站点进行了基于共享单车接驳的城轨站点可达性测度与评估。[结果及结论]在区域层面,站点可达性测度值呈现出在城市核心区普遍较高、近郊区分布范围广泛、远郊区普遍较低的规律;在站点类型层面,综合型站点的可达性测度值普遍较高,其次是办公导向型站点和居住导向型站点,职住偏移型站点和其他型站点的可达性测度值普遍较低。

[Objective]The shared bicycle is an effective connection tool for urban rail transit station.It is necessary to establish an accessibility measurement model to evaluate the accessibility of urban rail transit stations based on shared bicycle connection.[Method]Based on the data of shared bicycle transport and urban rail stations in Nanjing,the riding time,riding distance and the transfer volume of shared bicycles at each station are statistically analyzed,and the riding distance is selected as the accessibility evaluation index.The indicators such as mobility,convenience,accessibility and the impact factors of station scale are calculated,and an urban rail station accessibility measurement model based on shared bicycle connection is established.A cluster analysis of urban rail stations in Nanjing is carried out,and the accessibility measurement and evaluation of urban rail stations based on shared bicycles connection are carried out.[Result&Conclusion]From the regional perspective,the accessibility value is generally higher in the downtown area,and is widely distributed in suburban areas,and generally low in the outer suburbs.From the perspective of the station type,the accessibility measurement value of the stations with comprehensive function is generally high,followed by office-oriented stations and residence-oriented stations.The accessibility measurement values of the stations away from office and residence and other types are generally low.
