Evaluation of Urban Rail Transit Sustainable Development Based on the PSR Model

The purpose of this research is to analyze the connotation of the urban rail transit sustainable development from the following three aspects: social sustainability, environment sustainability, and economic sustainability. Based on the "pressure-state-response" (PSR) theory, this study builds the urban rail transit sustainable development evaluation index system which includes the following three sub-systems: pressure system, state system and response system. The PSR evaluation model of urban rail transit sustainable development is established, the calculation methods and solution approaches are proposed. Besides, in order to verify the feasibility of the model, a case study is conducted.
