VERIFICATION OF DESIGN PROCESS FOR IZUMISANO TOLLGATE ON THE HIGHWAY TO KANSAI AIRPORT

Abstract

The circumstances of the maintenance of the social infrastructure have changed greatly to the current era now that local residents' agreement and cooperation is obtained. In the past, infrastructure design done by engineers and experts usually could not reflect the intention of real users, and it was not well discussed in terms of the standard design, either. Using SD (Semantic Differential) evaluation method, this research verified the plan and the process of the design for Izumisano Tollgate on the highway to the Kansei Airport by comparing the design which general user evaluated with the decided one by a governmental design department. The new tollgate design by the authors was based on the opinions and suggestions of civil engineers and experts. As a result, the newly designed plan for the tollgate was found to be more appropriate than the previous official one.
