A Study on Road Network Designation to Complement Emergency Transport Roads

Abstract

In our country, emergency transportation roads have been designated for the purpose of facilitating the transportation of goods, personnel, etc., including evacuation and rescue. In this study, we will investigate how to set up a road network that complements emergency roads and connects necessary places. Specifically, assuming a situation where a vehicle loaded with relief supplies visits multiple evacuation shelters, a mathematical planning model is built to clarify how the complementary roads should be established in order for such operations to be carried out effectively. Next, we will apply this model to an analysis of central Tottori city and consider the effectiveness of the proposed method through a case study.
