Road networks are among the social capitals that were constructed during a period of high economic growth in Japan; however, they have recently deteriorated, and the countermeasures have created challenges. Therefore, an increase in future long-term road facility rehabilitation is to be expected. During rehabilitation, lane closure and link closure will occur, and traffic capacity will be reduced over a long period. Therefore, it is necessary to consider the impact on users of the entire road network in terms of detours and congestion. In this study, it is assumed that long-term road facility rehabilitation is planned at multiple road sections in the network. Considering the combination of long-term road facility rehabilitation and regulation methods, this problem is described as a network design problem, and a model can solve the traffic restriction schedule of long-term road facility rehabilitation to minimize its impact on users.
