In recent years, from the viewpoint of integrated landscape formation and regional development, there has been a demand to improve the function of roads as public spaces in cooperation with roadside facilities and public transportation. Under these circumstances, road redevelopment involving space redistribution and roadside landscaping has been promoted, and various services and regional activities using road space have been developed in various parts of Japan.

　We are therefore collecting examples of road space restructuring and utilization in Japan and overseas, clarifying the organizational structure of projects, the use of subsidies and systems, design innovations, and maintenance and operation measures after maintenance, and examining the planning methods and effects of each project. We are working on proposals for road space restructuring and utilization methods that can enhance regional development and landscape formation through the integrated improvement of roads and other facilities, coordination of multiple projects, and effective utilization of regional activities.

　As the declining birthrate, aging population, and declining population of Japan enter into full swing, the strategic securing and utilization of open space has been discussed.
