Summary:An obvious limitation of discussions concerning the expressway system is the subjectivity and one-sidedness. In line with this, there is a need for an objective, quantitative and comprehensive design methodology for an expressway system. Thus, this research developed a methodological tool (CESDA) for policy-set design from multi-perspective viewpoints that would be practical and applicable to real-world and large-scale problems. Initially, a comprehensive logical system of factors and variables on expressway system design, with consideration on the various viewpoints of different stakeholders in the system, were wholly constructed. A practically applicable mathematical model and system design analyzer was then developed using a tri-level model structure. An algorithm, which can deal with large-scale expressway policy-set design problems was proposed and verified. To verify its applicability, the expressway system of Japan was used as a case study. The optimal set of expressway expansion projects in the Construction Plan was obtained and discussed.
