摘要：AbstractIn Japan, regional road network improvement project is evaluated by cost-benefit analysis. However, the conventional evaluation procedure would be inappropriate in case of step-by-step improvement in each link, due to its planning term over several decades. Moreover, some of facilities supposed to be trip destinations would be added or removed from the nodes during the planning term, which would influence on accessibilities of each node. This study proposes an integrated project evaluation model with improvement of links and facility-location on nodes. The proposed model enables a consistent evaluation to fulfill the accessibility requirement for the whole nodes, considering the order of each project.
