Abstract： In order to better explain the low passenger volume of rail transit network in Tianjin and promote the coordinated development of urban transportation and land use, this paper proposes the techniques for analyzing the spatial distribution of job-housing based on cellular data. Through discussing the relationship between rail transit network and urban spatial structure, the paper analyzes the urban spatial structure in Tianjin in three aspects: commuting circle, Central Business District, and commuting travel linkage. The results show that the coordination between the existing or recently-constructed rail transit network and urban spatial structure in Tianjin is generally not very good, and there is a large room for improvement. The paper emphasizes that a regular assessment should be carried out on the relationship among the job-housing spatial distribution, urban land use development and rail transit network based on cellular data, which can provide scientific basis for the rail transit network development and the adjustment of urban land use development.
