The emergency supplies in large-scale natural disaster is affected by the dynamics of transportation network. The travel speed and link capacity change over time because of traffic accidents, landslides, and uncertain weather, etc., which block up the processing of emergency material transmission sometimes. Finding out critical links and knowing how these links affect the transportation are benefit...
The traffic congestion changes over time in the real transportation network, and the vehicle navigation is a real-time processing. Both the accuracy and time performance of navigation algorithm are important. To respond rapidly to transportation network changes, this paper proposes two new dynamic shortest path algorithms based on the re-optimization method. The algorithms take full advantage of the...
Fast and reliable building damage analysis is crucial for survivors rescue and disaster management when a destructive natural disaster occurs which helps to limit life losses. For this purpose, a method was developed in this paper to extract building's geometric axis line from aerial LiDAR data which helps to do further building damage analysis like to identify inclined buildings. To extract building's...
