Analysis on the Location Advantage Value Based on Roads and Towns

The location advantage value is an important index to indicate current and potential regional economy and social development situation.Based on roads and towns which are primary influence factors toward the regional economy and social development,this paper studies the theory and method of the location advantage value.This paper identified the density of the traffic net, influence value of traffic trunk and town as the fundamental index.According to the influence of the traffic and towns toward the social development,this study sets up the traffic net density value,traffic trunk and town influence value model and model of the location advantage value with the square root method.This study realizes the calculation of every location advantage value model with the GIS and grid technique.Setting the Zezhou County as the object, this study applies location advantage value models and technique adopted to conduct an analysis of the verification.The result is coupled with the practical condition fairly,which indicates that these models and technique are applicable.
