Abstract
Recently, the number of ambulance dispatches, arrival time to the accident site and the travel time to health facilities has increased due to aging. For building a safe and reassuring community, it is indispensable to respond quickly to emergency medical care, and there is an urgent need to improvement of road networks and efficiency of emergency facilities. In this study, we analyzed traveling historical data of ambulance in Tajimi City and Toki City, Gifu Prefecture, and we propose a method of road development plan for improvement of ambulance transport. We will consider the method of proposing a road improvement plan for ambulance transport to improve the life-saving rate by collecting and analyzing the travel history data (probe data) of ambulance in Tajimi City and Toki City of Gifu Prefecture . Specifically, we developed a link travel time database for emergency travel of ambulances, get the arrival time to the accident site, and developed the reachable area map of the ambulance using Dijkstra method. Using the map we developed, we got the speed reduction point of the ambulance and the arrival delay area of the ambulance, and we proposed to improve the traffic and its effect.
