Abstract
The maintenance of accumulated road stocks has been an important issue in the national land policy in current Japan. It is difficult to continue managing the current state of the road stock with the current budget, taking the prospect for the increase of maintenance cost in the future into consideration. In addition, the road with low importance may be needed to eliminate accordingly in order to decrease maintenance cost because Japan has entered the depopulating society and the smart shrink has been proposed. On the other hand, there will be trouble in the civil life if roads are eliminated recklessly. It is necessary to reduce the amount of road stock strategically, satisfying the demanded movement of citizens. We have proposed a community road network design model that determines the network shape satisfying the constant travel time in community roads. In this paper, we proposed to extend these models to practical applications that enable to consider multiple maintenance strategy, transit mode and timing of evaluation.
