An Intelligent System for Emergency Traffic Routing

Under natural disasters such as typhoons, hurricanes, floods and so on, it's necessary to evacuate the affected population to safe shelters quickly, and the large-scale emergency traffic routing becomes more and more important. An intelligent system for emergency traffic routing was proposed in this paper. The evacuation road network was extracted from GIS, the cell transmission model (CTM) was used for the allocation of evacuation routes. Then the numerical solution was tested by the traffic evacuation software CORSIM. After that the determined evacuation routes were shown in GIS, so that the traffic evacuation can be guided better and more intuitively. With a case study, it shows that the system can provide helpful guidance and assistance for emergency evacuation.
