The sphere of evacuation facility based on the facility choice behavior model - Analysis in Sendai city, Natori city and Iwanuma city by the data of archives for reconstruction

This paper reports evacuation facility choice behavior for Tsunami evacuees in coastal areas of Miyagi prefecture, based on the data of Archives for Reconstruction after the Great East Japan Earthquake. The choice behavior was modeled by using a logit model. This model is constructed considering psychological cost of evacuation, distance from evacuee to evacuation facility, height of evacuation facility, footprint of evacuation facility, and the height above sea level of evacuation facility. We compared the sphere of disaster evacuation by logit model, the sphere of voronoi diagram and the sphere of voronoi diagram with a restricted direction to facility.
