摘要

Recent advances in network science have encouraged researchers to adopt a topological perspective in network assessment. This represents a paradigm shift from traditional network analyses for which the primary focus was flows. In this paper, we present a comprehensive topological investigation of the Road Traffic Network (RTN) of the Western Regional Megapolis in Sri Lanka. We identify the critical nodes (intersections) and links (road sections) within the RTN based on various network theoretic metrics. In addition, we assess the topological robustness of the RTN based on sequential failure (both random and targeted based on connectivity) of the intersections in the system. Our findings could inform policymakers in prioritizing the scarce funds available for future infrastructure investments.
