国内各城市轨道交通线网平均乘距和各线路平均运距统计分析——基于中国城市轨道交通协会数据分析的研究报告之四

Analysis of Urban Rail Transit Average Network Riding Distance and Average Line Haul Distance in China——Report 4: Data Analysis of Urban Rail Transit Association of China

基于中国城市轨道交通协会的统计数据,从空间维度横向统计分析了24个城市的轨道交通线网平均乘距和各条轨道交通线路的平均运距(共计108条);从时间维度纵向比较了2015—2017年24个城市的轨道交通线网平均乘距变化情况。基于K-means聚类算法的计算结果分析了线路类型和线路里程与线路平均运距的关系。主要结论为:线网平均乘距与城市建成区规模呈正相关关系,职住分离是导致线网平均乘距较大的主要原因,新增线路性质和新增线路与既有线网的连接方式对线网平均乘距影响较大,线路类型和线路里程是影响线路平均运距的主要因素。

According to the statistical data of China Urban Rail Transit Association,the average rail transit network riding distance of 24 cities and the average rail transit line haul distance of 108 lines in China are horizontally analyzed from the perspectives of spatial dimension,the changes of the average rail transit network riding distance during 2015—2017 period are compared vertically from the perspective of temporal dimension.On this basis,the relationship between the line type,line mileage and the average network riding distance is analyzed based on the calculation results of K-means clustering algorithm.It is concluded that the average rail transit network riding distance is correlated positively with the scale of urban built-up areas,the separation between jobs and residential locations is the main cause for the expansion of average network riding distance,the nature of new lines and their connection mode with the exiting line network have larger influence on the average network riding distance,while the line type and line mileage are the main factors to influence the average line haul distance.
