城市轨道交通线网规模与人口和岗位密度之间的关系

Relationship between Urban Rail Transit Network Scale and Population/Job Density

人口密度与岗位密度是确定城市轨道交通线网规模的重要指标,但如何表征人口密度和岗位密度指标与线网规模的关系有待进一步研究。选取城市轨道交通线网密度作为衡量线网规模的指标,对国内外典型城市的轨道交通线网密度、线网负荷强度、人口密度、岗位密度、人口密度加岗位密度、人口密度与岗位密度中较大值等进行关联性分析,研究城市轨道交通线网密度与人口、岗位密度指标之间的关系,并比较亚洲和欧美城市轨道交通线网密度与人口、岗位密度之间关系的差异,为合理确定我国城市轨道交通线网规模提供借鉴。

Population density and job density are important indicatorsto determine the scale of urban rail transit network,but further studies are needed to confirm the relationship betweennetwork scale and population/job density.So the densityof urban rail transit network is taken as the index to measurethe scale of the network,the correlation among urban railtransit network density,network load intensity,population density,job density,population density plus job density,thegreater value of population density and job density is completedwith the data collected from the major cities in Chinaand abroad.All the data are used to investigate the relationshipbetween urban rail transit network density and population/jobdensity,and the differences between Asian cities,Europeancities and American cities in this area are compared to providea reference for the planning of rational urban rail transit networkscale in Chinese cities.
