In Japan, many local governments are reviewing authorized road plans which have not been built for long time based on changes in socioeconomic conditions. Many of these local governments are evaluating such routes to perform various functions of road, examining if they are still needed, and then, eliminating planned routes once they are determined no longer necessary. Meanwhile, authors consider road network should be restructured based on cities' vision (urban structure), rather than discarding unnecessary routes by comparing with the roles of road, and suggested a planning framework to achieve the vision earlier. In this paper, we describe a concept of evaluation for authorized road plans corresponding to the proposed planning framework, and verify the effectiveness using the review of authorized road plans in Saitama City as an example.
