Study On The Location Public Parking Lot Based On GIS

With the rapid development of China’s economic, the size of the cities is increasing, the number of motor vehicles in cities is also growing rapidly, then road traffic problems appear. An important means to solve the above problem is to establish the city public parking lot. But most of our urban cities exist a lot of problems in the city public parking lot. The problems mainly reflect in:unreasonable layout, small scale and fewer parking spaces, etc. Most cities in China can only provide one-third of the vehicle population in the parking currently. Public parking in the road outside provides a public parking lot for travelers engaged in various activities. Its service object is wide and has the greatest impact. So expanding and building urban public parking is an important means to solve the problem of parking. Reasonable layout of the public parking has a great significance on improving people’s living standards, rational use of land planning and building harmonious urban environment. With the development of GIS, urban GIS is applied to many aspects of the current economic construction, but the application of GIS in urban social public parking’s location is less mentioned yet.Based on predecessors’researches, this thesis introduces the effect factors of public parking’s location, several traditional public parking location models and the fundamental and application of GIS. The research indicates the weakness of the traditional location method and the advantage of the GIS’s application in public parking lot location method.This thesis combines GIS multi-criteria decision making analysis and the location of public parking, then it proposes the location model multi-criteria decision making based on the Analytic Hierarchy Process (AHP)GIS analysis. The total of the shortest path distance to all the interest points in function area is the minimum.Taking a relevant data of Songzi, Hubei province for example, the thesis designs the AHP model, and use ARCGIS10.0software. Through the integrated use of GIS network analysis, buffer analysis overlay analysis, the thesis achieves the objective select of public parking location’s impact factor and comprehensive weight assignment. It assesses the berth requirements in this city through population density and the nature of land. By comparing the experimental output with berth assessment, the thesis verifies the feasibility of the technical program. At the same time, it finds some in adequacies of the previously proposed model by experiments, and brings about some improved program.
