Accessibility Assessment of Cities Based on Network Analysis and Centrality

This study is assessing the level of city accessibility in the regional planning context special referenced of the Northern region, Sri Lanka. The study carried out through the two consecutive methodologies which were frequently used in modern transportation context, namely “Network Analysis (Shimbel Index)” and the “Centrality Analysis”. The results indicate that accessibility measured by “Network Analysis” shows the accessibility concentrated to the center of the region as Christaller central place theory discussed. Hence, Centrality analysis approach here measured under the two major approaches as identified Closeness and Betweeness centrality and the results show a realistic interpretation considering the local level connectivity of the Northern region road network. It’s also evaluated the correlations and validity of the two consecutive approaches while measuring the different accessibility levels and centrality approach shows higher level correlation with the population density figures of the region.
