Abstract
Currently, efforts to maintain road infrastructures efficiently has been focused in Japan. However, the budget and human resources are limited in small municipalities compared with the national government. Therefore, it is difficult for small municipalities to adopt the same method as the national government or large municipalities. An efficient maintenance plan, that can be adopted by small local governments, is needed. Gifu prefecture adopts a comprehensive maintenance planning, named “Infrastructure maintenance Plan,” in order to improve the efficiency of investment by dealing with repair necessity of multiple structures unitarily based on risk assessment. However, it is difficult for small municipalities to adopt risk assessment because a lot of data is needed. In this paper, we develop the popularized maintenance planning model for road infrastructures based on risk assessment. We tried the developed model on existing roads and verified its appropriateness by comparing it with the priority order by AHP and the priority order by administrator's decision.
