This study applies graph theory to quantitatively evaluate the structural integrity and resilienceof Karbala’s urban road network. By modelling roads as edges and intersections as nodes, we assess the systemusing key metrics such as meshness, organicity, betweenness and closeness centrality, and global efficiency. Thereliability of each road segment is evaluated using an exponential failure function derived from segment-specifictravel times and estimated failure rates. Findings reveal moderate to strong connectivity and resilience withareas for potential enhancement, particularly in reducing the network’s diameter and improving redundancy.These insights support urban planning strategies aimed at enhancing infrastructure robustness
