Novel Strategies for Road Network Disruption Analysis

Road (or street) networks refer to interconnected systems of streets, roads, and pathways which constitute the transportation infrastructure within a city or urban area. These networks play a crucial role in urban planning and design, as they influence various aspects of city life. There are several key elements to be considered in the study of street networks: hierarchy, grid and patterns, connectivity, walkability, transit integration, traffic flow, land use and zoning, and smart mobility solutions. In this study, we use social network analysis tools to identify the most effective strategies to simulate and assess the impact of road network disruption. Our scenario has been constructed by building a road network based on a portion of the geographic map data of Messina (Italy) and implementing random and targeted attacks based on edge centrality measures and street types. The impact of our strategies on the road network structure is evaluated in terms of connectivity.
