Abstract

Abstract: The service radius study is an important embodiment of the rationality of facility's layout.The defect of traditional research is that the theory-base radius lacks the verification of actual data.In this paper,authors propose a method which analyzes the service radius of the facilities based on taxi trajectory data and then verifies the validity of the method using the tertiary hospital of Shenzhen city.The result shows that the visitors of the tertiary hospital in Shenzhen are mostly within 9.km and 4.km may be a reasonable service radius.From the perspective of the spatial distribution of the healthcare facilities service area in each district,the layout of the tertiary hospital in Shenzhen shows relatively imbalance.However,the spatial distribution of tertiary hospital is not far from that of the population density through centroid analysis.

Key words: GPS trajectory, healthcare facility, service radius, spatial layout
