基于手机信令数据的上海市域职住空间分析

居民居住地与工作地的空间关系是城市空间布局的重要依据.基于手机信令数据,提出分区域的居民通勤距离和就业岗位通勤距离计算方法.通过对比验证了手机信令数据与居民出行调查数据的职住空间和距离分布特征较为吻合.重点分析上海市中心城区及周边地区的职住空间关系及通勤距离.提出职住通道平衡概念,并分析职住通道不平衡地区与轨道交通拥挤程度的关系,指出土地利用布局优化对职住通道平衡的重要性.通过分析不同新城的职住空间特征,探讨新城范围划定对统计分析的影响,总结了新城职住空间较为独立、居民内部就业率较高的特征.

Job-Housing Spatial Distribution Analysis in Shanghai Metropolitan Area Based on Cellular Sig-naling Data

The spatial relationship between residence and workplace primarily determines the urban spatial layout. This paper proposes a methodology to calculate commuting distance between residence and work-place by region with cellular signaling data. The comparison result shows that job-housing spatial distribu-tion and commuting distance obtained from both travel surveys and cellular phone data are very similar. Through analyzing the job-housing spatial distribution and commuting distance in the central district and surrounding areas in Shanghai, the paper proposes a concept of balance in job-housing corridors. By re-viewing the relationship between regions with imbalanced job-housing corridors and the degree of rail tran-sit congestion, the paper emphasizes the importance of land use development for the balanced job-housing corridors. The paper discusses the zoning size impact of a new town on the statistical analysis through ana-lyzing job-housing spatial characteristics at different new towns. The result shows that the job-housing dis-tribution of new towns are relatively independent, and the employment rate of residents within new towns is relatively high.
