摘要: 基于相关研究，提出一种定量化测度轨道交通（以下简称“轨交”）线网与城市中心体系匹配程度的方法。以功能联系为
基础，使用多源大数据量化分析轨交线网与上海城市中心体系匹配程度。从轨交刷卡数据中依据乘客使用轨交出行时空
规律，获取轨交通勤出行、轨交游憩出行的功能联系，用于表征轨交功能联系下的就业中心体系、公共活动中心体系。从手
机信令数据中获取用户的通勤出行、游憩出行的功能联系，用于表征全方式出行功能联系下的就业中心体系、公共活动中
心体系。随后分别使用规模等级一致性、来源范围一致性指标，量化分析轨交线网与就业中心体系、公共活动中心体系的
匹配程度。研究结论认为除了轨交线网与中心体系的空间关系之外，就业中心的产业特征、公共活动中心的职能也影响了
轨交线网与城市中心体系的匹配程度。
Abstract: This study presents a method for quantitatively measuring the degree of matching between rail transit network and urban center
system. Based on functional linkages, the degree of matching between rail transit network and Shanghai urban polycentric system is
quantitatively analyzed using multi-source big data. Firstly, according to the spatial-temporal regular pattern of rail transit passengers
using transit smart card data, the functional linkages of commuting and recreation trips by rail transit are obtained, which is used
to indicate the employment center system and the public activity center system in the perspective of rail transit functional linkages.
Using cellphone signaling data, the functional linkages of commuting and recreation for full travel mode are obtained, which is used
to indicate the employment center system and the public activity center system in the perspective of functional linkages for full travel
mode. Then the indicators of size rank consistency and source range consistency are used to quantify the matching degree between
the rail network and the employment polycentric system and the public activity polycentric system. It is found that in addition to the
spatial relationship between the rail transit network and the center system, the industrial characteristics of employment center and the
functions of public activity center also affect the matching degree between the rail transit network and urban central system.
