Strategic planning for emergency response is critical for effective response to natural or deliberate disasters. Response vehicle routing and evacuation of the affected people are part of emergency response operations under disasters. The response vehicle routing seeks to rescue the distressed population and deliver relief support to the affected locations in minimum time, while the evacuation component aims to quickly relocate the affected people to safe locations. The difference between these activities is that they are typically conducted in opposite spatial directions, that is, to and from the affected area, respectively. This characteristic of emergency response operations presents challenges in terms of routing, in addition to time constraints. Moreover, the road network state under a disaster can be time-dependent, since the link (or node) capacity/availability is known only after the disaster occurs (or spreads), and as information is received or updated over time. This study addresses the problem of dynamic routing operations in the emergency response context, primarily in terms of the routing of response vehicles and evacuees. The study focuses on identifying the paths used for routing response vehicles and the evacuees in disaster situations. In this context, two application modules are developed: a module for K-shortest paths routing and a module for multiple-stop routing. The K-shortest paths module allows more flexible options for routing response vehicles under the dynamic network conditions due to a disaster. It provides multiple routes for evacuation and response operations. The multiple-stop routing module enables the delivery of relief resources to several locations using a single response vehicle.
