Characterising the structural pattern of urban road networks in Ghana using geometric and topological measures

Road networks are an integral part of any human settlement, facilitating the movement people, goods, and information. The structural arrangement a road network can have profound impact on its performance, mobility access to critical infrastructure. This study takes advantage computational science approach examine configuration using geometric topological descriptions in districts covering 10 regional capitals Ghana. majority urban were found follow radial pattern at global scale, with either gridded or branching local scale. Only Accra Kumsi fine grained comparable density other cities, based intersection street densities. Structural indicators such as circuity, clustering, page rank, degree centrality, betweenness centrality for roads Ghana be cities. Given lack adequate infrastructure traffic monitoring Ghana, spatial distribution could resource provide insight management. These findings basis inform transportation planning management issues, particularly, it is possible identify problematic locations within which most vulnerable congestion.
