Abstract:
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.
