Node Centrality and Road Accessibility in Mountainous Area: A Study of Aizawl District, Mizoram

This study explores diverse methods to quantify node centrality in networks. The approach focuses on direct and indirect node interactions, investigating their influence on centrality and road network accessibility in hilly areas. Such an approach allows us to elucidate how a node is structurally connected to other nodes in the network and its components. The research establishes metrics for assessing node centrality in hilly road networks using specific measures. It highlights critical nodes, linking spatial interactions, centrality, and accessibility. By utilizing geospatial technology, the study maps node centrality in the Aizawl district, potentially guiding road network design to effectively address transportation and resource allocation issues.
