In mountainous regions, it is unclear how effective the role of forest road development is in building disaster prevention infrastructure. In this study, we developed a method to quantify the function of forest roads by improving the existing method for evaluating connection vulnerability to support the evaluation of public benefit from forest road projects. This study was conducted in Gujo City, Gifu Prefecture. Here, the function of alternative roads of forest roads was conceptually organized and a forest road with an alternative route function was defined as a forest road included in a set of non-overlapping routes (evacuation route set) that minimizes the time required while maximizing the number of non overlapping routes between evacuation origins and destinations. Furthermore, the evacuation route set could be obtained as a solution to the minimum cost-maximum flow problem between the starting and ending points. As a result of evaluating all evacuation route sets between the origins (225 evacuation centers in the city) and the destination (Gujo City Hall) in the study site, forest roads were included in the evacuation route set for ~65% of the evacuation centers. Thus, the proposed method can evaluate the alternative route function of forest roads only from the perspective of network topology and not from the perspective of disaster risk.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"96034","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE,
