Abstract:

In order to improve the efficiency and effectiveness of traffic organizational decisionmaking for emergency evacuation. On the basis of information centrality theory, the concepts of key nodes, efficient key nodes and connectivity key nodes was put forward, and the method of identifying each kind of key nodes and key routes for emergency evacuation was designed. A case study based on the actual road network and practical traffic data was presented to demonstrate the effectiveness and feasibility of the proposed method.

Key words: engineering of communications and transportation system, emergency evacuation, information centrality, key nodes, key routes
