Earthquakes are one of the most significant natural hazards threatening Tehran Province, with potential to severely damage critical infrastructure, including road networks. This research aims to evaluate the vulnerability and resilience of Tehran Province's road network against earthquakes using Geographic Information Systems (GIS). The study data includes shape files of Tehran Province, urban and provincial roads, fault lines, earthquakes from the past four decades, healthcare facilities, fire stations, and shelters, all analyzed in ArcGIS Desktop environment. Using Hot Spot analysis and density analysis, areas with high concentration of earthquake occurrences were identified. By creating a 10-kilometer buffer around fault lines and conducting overlap analysis with the road network, it was determined that 60.73 percent of the entire Tehran Province road network and 88.43 percent of Tehran city's road network are vulnerable to earthquake damage. Through network creation and conducting routing and facility allocation analyses, strategies for improving access to emergency centers during post-earthquake crisis situations were developed. The results of this research can significantly assist planners and crisis managers in enhancing the resilience of Tehran Province's transportation network and reducing its vulnerability to potential future earthquakes.
