A Study On The Relationship Between Regional Economic Development And Road Network Density In Bulgaria

Abstract

The subject of this study is the correlation between road network and regional economic development in Bulgaria. The research hypothesis is based on the presumption that there is a positive correlation between the density of the road network and the regional economic development in Bulgaria. This article aims to analyse the relationship between regional GDP per capita (in BGN) and the density of same-class roads by province (in km.) by means of graphical correlograms.
