Abstract

 In response with East Japan Great Earthquake, the Japanese Ministry of Land, Infrastructure, Transport and Tourism has announced the evaluation method of the function of road in emergent situation. In the announced method however the benefit of such function is not evaluated by the monetary term and the method is therefore not consistent with the conventional benefit evaluation method. Based on the above background, we propose 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. We found that there are effective roads and low effective roads under disaster.
