Connection Facility Layout Model of Subway Stations

Abstract

As the key node of public transportation system, subway station has many functions such as attracting and distributing passengers and guiding the transfer from various traffic modes to subway. However, the poor facility scale and layout around subway stations in practice usually cause the inconvenience of transfer and low transfer efficiency, which causes the declination of travel efficiency and even loose of subway passengers. Taking subway stations as the study objects, this paper has emphasis on the connection characters between various traffic modes and subway stations. Considering the attraction region, the total transfer time, transfer distance, and connection cost were selected to form the efficiency index of connection layout of subway stations. Data envelopment analysis (DEA) model is applied in the quantization of traffic resource consumption and output. At last, connection facility layout model of subway stations was established with the aim of improving the transfer efficiency. Meaningful results were obtained from the connection layout model of subway stations, which guide the planning and designing of the transfer facilities around subway stations.
