抄録

The purpose of the paper is to develop a method to estimate benefits and costs of related groups and to present a balance sheet for equitable cost bearing for suburban road improvement projects. First, the paper proposes the estimation of benefits by the increment of property value which should capture the secondary benefits as well as the disbenefits such as noise and air pollution on highly effected areas by the project and by the user's benefit in other areas for supplementation. Second, Hachioji-By-Path project is chosen for ex-post analysis. Then the study estimates the land price function which can identify the benefits of accessibility, environment as well as land use change by the project.
The benefits and costs of road users, landowners, community and local goverment, ministry of construction are estimated based upon changes of the property value and users benefits with and without the projects. The results show the applicability of the method for equitable cost bearing of suburban road project.
