Traffic organization method for emergency evacuation based on information centrality

Large-scale natural or man-made disasters have the potential to cause great loss of life, human injury and extreme property damage. Evacuation from areas at risk is often one of the most feasible strategies that can be undertaken in response to these types of disasters. Evacuating a large population in the shortest possible time is an extremely complicated and difficult task, which primarily relies on efficient method of traffic organization for emergency evacuation corridors. This paper, on the foundation of efficiency and contingency, puts forward a novel method of emergency evacuation traffic organization using information centrality of complex network theory, the characteristic of which integrates a method of emergency evacuation corridors optimization and traffic organization method of emergency evacuation corridors. In addition, the efficiency function in information centrality has been improved. The experiment results show that the proposed method has rationality and feasibility.
