Abstract

Spatial inequality in transport access is both the driver and outcome of rising economic inequality in Southeast Asia. Unlike many regional disparity studies that focus on national economic indicators, this paper takes an urban network approach to assess the spatial inequality in Southeast Asian intercity transport network. We analyze urban connectivity in intercity road, rail, and air networks for a total of 47 Southeast Asian cities. Spatial inequality at the city and network level is revealed via centrality measures and community detection, respectively. Gini coefficients for individual centrality rankings point to a hierarchical degree distribution, a rather even distribution of closeness centrality, and a highly concentrated distribution of betweenness centrality. Four network communities are identified, reflecting the influences of entrenched uneven development, fragmented geography, and economic and political policies.
