Abstract

“Emergency Link” that will become effective in the case of large disaster is predetermined by Prefectures to cope with transport demands such as emergency transport and humanitarian logistics. For this, the road managers are strengthening infrastructures along emergency links to avoid disconnection. However, the investment cost may become large if one designates emergency links without consideration of the efficiency of investment. This paper proposes a model that designates emergency links with minimized total reinforcement cost by optimally selecting two levels of reinforcement strategies while satisfying the connectivity requirements. The proposed model is tested on Gifu prefectural road network, and we confirmed the trade-off between the required number of paths and the investment cost by the sensitivity analysis. We also confirmed the trade-off between allowable travel time and the investment cost. Therefore, road administrator need careful consideration in determining these parameters.
