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: module for K-shortest paths routing and 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. It has the ability to impose time window constraints for relief operations and the reordering of the routing to the delivery locations, capabilities which are critical to disaster operations. For ease of operability, these modules are developed on a Geographic Information System (GIS) platform used by the Indiana Department of Transportation (INDOT) and Indiana Department of Homeland Security (IDHS). Based on dynamic field conditions, color-coded flags on the GIS map are used to characterize links in terms of their availability and functionality in the context of the response operations.
