Study on Acceptance and Stockpiles Management at Temporary Accommodation Facilities for Evacuees After an Earthquake Based on Behavior Analysis

Key Points

The research aims to analyze the spatial distribution and management of evacuees in temporary facilities post-earthquake.
Quantitative analysis of evacuee distribution based on scenario modeling.
Evaluation of occupancy and sufficiency rates of facilities over time.
Consideration of supply characteristics and facility locations during disaster scenarios.
Integrating evacuees can reduce occupancy rates by over 100% compared to separate management.
The amount of needed stockpiled supplies is influenced by supply types and disaster timing.

Abstract

Based on pseudo-people flow, this study quantitatively clarifies the spatial distribution of stranded individuals at the time of disaster occurrence and the occupancy and sufficiency rates of various facilities after a certain period across multiple scenarios. The analysis reveals that integrating evacuees into temporary facilities and designated shelters without distinction can reduce the occupancy rate by more than 100% compared with implementing separate management. Furthermore, estimating the necessary amount of stockpiled supplies requires a comprehensive approach that considers not only the characteristics of supplies but also the facility locations and time of disaster occurrence.
