Abstract:

Service quality of seismic emergency shelters is an important reference of seismic planning. Spatial coverage of seismic shelters has been used for evaluating service quality of seismic emergency shelters. However, population distribution and evacuation behaviors were rarely considered, which rendered the evaluation results inaccurate. Based on a multi-agent simulation model, this study examined earthquake evacuation behaviors, such as choice of destination, routing, and sheltering. Evacuation rate—the rate of evacuees who successfully arrived at seismic shelters to take refuge within a specific time period—was then calculated. Coverage rate of emergency shelters and evacuation rate of residents both were used to indicate the evacuation success rate. A case study was conducted in Haidian district. The evaluation result shows significant difference between the spatial coverage rate of seismic shelters and evacuation rate. It indicates that coverage of emergency shelters alone cannot fully evaluate emergency shelters. Coverage rate of seismic shelters together with use efficiency of emergency shelters and signs for evacuation routes that lead to quick and order evacuation are all crucial indicators for evaluating service quality of seismic shelters.

Key words: seismic shelters, service quality, evacuation behaviors, spatial accessibility, multi-agent simulation
