Analysis of Spatial Distribution of Parking Lot in High Density Urban Area Based on Voronoi Diagram: Take Haizhu District in Guangzhou City as a case

Abstract

As the important part of infrastructure in high density urban area,spatial distribution of parking lot relies on population,roads and buildings.Under the influence of various factors,parking lot in high density urban areas owns a specific distribution rule.Combining GIS with Voronoi diagram,we discussed the spatial distribution characteristics and co-agglomeration of parking lot in high density urban areas,and analyzed the spatial autocorrelation between parking lot and various factors.Taking Haizhu District in Guangzhou City as a case,we calculated CV value and clustering index by building Voronoi diagram in the researched area and streets.Through the analysis,we know that the parking lots agglomerated markedly in the whole district and every street.In high density urban areas,parking lots tend to gather in commercial circle and economic center such as Jiangnan Road commercial circle and center section of Guangzhou new axis which run through Haizhu District which are the cluster center of parking lots.It showed that population density,building density and road density affect the spatial distribution of parking lots obviously with two variable regional spatial autocorrelation analysis,which population density perform more significantly.Higher the development level of the high density city,more obvious the effect of various factors on density and the degree of agglomeration of parking lots.
