Abstract
In this study, in order to evaluate the benefits of the inter-city transport projects, we built the calculating system of the minimum generalized costs. We also built the system on calculating the benefits of the inter-city transport projects using the national land price model considering the time and spatial repercussions. Moreover, we lead the formula of the error's possibility in terms of the estimated precision of the upper land price model and quantitatively verify of the satisfaction of small condition on the large transport projects. Finally, using these built systems, we measure the benefits of users by considering significance level, targeting the Akashi Kaikyo Bridge and the Kitan Kaikyo Road.
