A Study on the Location Characteristics and Facility Functions Affecting Utilization of Roadside Stations During Earthquake Disasters

This study analyzes factors influencing the utilization of roadside stations during major earthquake disasters. Logistic regression was applied to 97 stations near affected areas, classifying utilization into evacuation/stay, livelihood support, and relay hubs. Population scale and large-vehicle parking promoted evacuation use, while proximity to affected areas and the number of evacuation sites shaped livelihood support use. Relay hub use was driven mainly by proximity, suggesting unobserved qualitative and dynamic factors. These findings highlight the need for function-specific indicators and support more comprehensive disaster preparedness planning.
