  • 摘要:AbstractThis study analyzes the robustness of a road network under natural and man-made disasters through an index introduced by the authors based on the reachability matrix. As our main case study, we analyze the road network of Metro Manila by simulating destruction of random locations on the network. The road network used in this study was created using data from the Open Street Map mirror site, Metro Extracts. Results of this study show that the Metro Manila road network is fairly robust up to 1 km radius of destruction, where a maximum of 4.86% paths disrupted is incurred. However, the damage sharply increases for larger radii of destruction. Five percent or more loss in the network's connectivity is noted in 13.8% of the nodes for the 2 km radius and in 77.3% of the nodes for the 4 km radius.
