This study evaluates the efficiency of the network road in Benghazi city for the year 2024 using Geographic Information Systems (GIS) techniques, addressing the significant disparity between rapid urban expansion and the current network's capacity to achieve spatial connectivity. The study aims to analyze the quantitative and topological characteristics of the network and measure accessibility and connectivity indicators using Network Analyst tools. The research adopts a quantitative analytical approach, utilizing field survey data and updated Open Street Map (OSM) data, processed alongside demographic and geographic data via ArcGIS 10.8. The analysis includes calculating connectivity indices (Alpha, Beta, and Gamma), distance and link matrices, and assessing the impact of geomorphological and climatic factors on pavement durability. The results revealed a sharp separation in accessibility the central district (New Benghazi and the City Center), which recorded the lowest cumulative distance (157.91 km), compared to a clear spatial isolation of the edges (Sidi Khalifa and Qanfouda), where cumulative distances exceeded 352 km. Furthermore, the study disclosed a weakness in the overall network integration, with a road density of 1.21 km/km² and low Beta and Gamma indices (0.140), reflecting a lack of alternative routes. Engineering-wise, it was found that the network faces hydraulic and climatic challenges threatening pavement integrity due to the intersection of road paths with natural valleys and the susceptibility of asphalt materials to a wide thermal range and high humidity....................
