Abstract:

This paper formulates an emergency response strategy for the efficient blocking of a suspicious vehicle that may have been hijacked by terrorists as a potential weapon of terrorism attack in urban area. Two primary cases are considered. The first case aims to minimize the resources required to thoroughly block a suspicious vehicle whereas the second case aims to maximize the effectiveness of the blocking scheme given limited resources. In the first case, an enhanced cutset algorithm is devised to locate all the junctions/links to be blocked while reliability analysis is employed in the second case to obtain an optimal blocking scheme. Several criteria relating to the route choice behavior of the suspicious vehicle, including travel time, optimal path and road configuration, are considered. Analytical hierarchy process is used to derive the probability matrix for probabilistic analysis. Two approaches for calculating junction selection probability, namely candidate route search approach and Monte Carlo method, are provided and compared. Optimal dispatching schemes are generated based on the shortest path algorithm. A GIS-based intelligent emergency response prototype system is then developed by incorporating the proposed algorithms into widely available GIS software (ArcGIS). The system is tested using the road network of Calgary. The case study shows that the proposed system is able to generate an effective strategy for blocking a suspicious vehicle from critical infrastructure and automatically derive minimal travel time routes for emergency response units.
