Abstract:

Accessibility is truly simulated with the application of GIS network analytic technique to put into reality optimum allocation of infrastructure. Based on lessons drawn from former research findings, given full-scale urban development strategy of Dalian, distribution of primary schools of Xinghua Street in Ganjingzi District of Dalian City is studied as an example. By abstraction of data on residential areas and schools from high-resolution remote sensing images in the year 2012, combined with on-the-spot investigation, research and statistical data from Public Security Bureau, with migrant population taken into account, meanwhile, database of school-age population and school is established. By comparative study of minimum impedance model with some arithmetic application of such influence factors as lag time multiplied by velocity or time (sensu lato) and maximum coverage domain model with appropriate modifications involving the largest number of points in maximum service diameter and some demand points within coverage domain, an allocation schema for primary schools in studied district is identified, which is done in both small and steady stages over a period of time, rather than suddenly. The conclusion demonstrates these main points as follows : 1) The distribution of primary schools is not located well enough for the moment, and it should be improved to a much more advantageous situation with much more professional attention paid to technical analysis. 2) Primary school location based on the principle of maximum coverage is more reasonable, which presents a striking contrast between different ones. 3) It is advised that Xinghua Primary School, Songjianglu Primary School, Qianshanlu Primary School, Huazhong Primary School and Furong Primary School should be located in the original spots. 4) It is relatively reasonable to allocate 2 primary schools in No.2 and No.45 spots.
