| Research Abstract |
We propose a robust network design model which can contribute to construct a network which may function under an emergent situation. For this we first proposed a benefit evaluation method of disaster prevention capability of road network consistent with the conventional benefit evaluation method. In concrete, we define the benefit of disaster prevention capability of the road as a sum of reduction of economic loss by detouring and losing opportunity, and reduction of anxiety of being disconnected for local citizen. The proposed method is applied to the road network in Hida area of Gifu Prefecture, and the benefit of enhancing connectivity by new road construction is quantified by the monetary term. Then we carried out a web-based questionnaire survey to estimate a parameter for a reduction of anxiety of being disconnected.
