Identification of Important Sections for Emergency Rescue Road Network

摘要

Quick and accurate identification of important sections for emergency rescue road network is of great values to emergency rescue transport program, command and control and other transport services as well. Regarding inadequacy of current research in this field, this paper proposes a model of identification of important sections for emergency rescue road network based on GERT network. Firstly, a matrix algorithm of seeking the network of the biggest connectivity map between multiple rescue points and multiple accidents points of road network is designed; secondly, conceptions concerning sections importance of road network are defined and GERT network model algorithm of sections importance for road network is designed; and finally, this paper introduces the application of this model by an example and verifies its feasibility and effectiveness.
