The GIS-Based Research of Measurement and Planning on Walkability of Educational Public Service Facilities - A Case Study in Wuhan

Abstract

Pedestrian traffic--- the most encouraged way of developing the "green travel mode" nowadays, makes urban walking quality an important index to measure city residents’ quality of life. While the needs of vehicular traffic were continuously met, the pedestrian traffic should be taken into consideration as well. This paper exemplifies an empirical study on walkability measurement towards the educational public service facilities of Wuhan (capital of Hubei Province, China) and integrates the factors of transport, population and land use on the basis of GIS, to verify the rationality of the layout of these facilities. Mainly by analyzing the allocated situation of the city’s educational service facilities and grade distribution of walking demands, together combining with the attenuation of both walking distance and pedestrian conditions, it draws some conclusions (assisted by application of GIS overlay analysis calculation) on the city’s comprehensive pedestrian grade distribution with regard to the city’s educational public service facilities, which will propose some beneficial guidance for the layout planning of facilities.
