From Infrastructure to Urban Life: An Interpretation of Comprehensive Development of Existing Railway Land in High-density Urban Areas
Abstract：
In order to meet the demands of increasing population and economic development in high-density urban areas, and to solve the contradiction between supply and demand of land, the capture of development rights over existing railway tracks and yards, which occupy a large scale of urban land resources, has gradually become a focus of attention in the exploration of comprehensive development of infrastructure. On the basis of sorting out the evolution of the relationship between rail transit facilities and urban space, and various modes of comprehensive development over rail facilities, this paper focuses on the comprehensive development projects building above the existing rail facilities, which involves higher technical difficulty and more complex stakeholders. Based on the cases study of the Hudson yard project, Sunnyside yard project and the Philadelphia 30th street project, this paper attempts to interpret the motivation, common features, spatial organization logic and operating mechanism of such kind of developments. Furthermore, the prerequisite elements of necessity and feasibility of the mentioned project are summarized in order to provide reference for later research and practice of similar development of existing railway land.
