Description

 To improve the safety and security of driving while coping with today's stagnant economy and frequent natural disasters, road slopes should be appropriately managed. In order to achieve the goals, road managers should establish management methods in road slope disaster prevention by clarifying social losses that would result by drops in service levels. On the other hand, in order to manage an infrastructure appropriately, maintenance management plans, such as a bridge, pavement, a tunnel, are formulated individually. However, each of these institutions achieve a traffic function safe as a road network, and safe rather than achieve a function independently. Therefore, it is necessary to manage road slopes by evaluating a road as a network. It is important that road managers evaluate asset value of the slope in a road network to manage the road slope effectively. From this viewpoint, this study proposed "management methods based on asset value" in road slope disaster prevention, which evaluated as a road network.
