The major objectives of this report are to develop a benefit-cost methodology for the evaluation of intermodal projects in statewide transportation planning and to examine an institutional framework conducive to cost sharing by different modal-specific programs in the State Departments of Transportation (DOTs). In order to find an appropriate institutional framework for intermodal planning, a compendium of current best practices adopted by various states is included. Evidently, better coordination and cooperation among modal-specific programs seems to be the preferred institutional framework for implementation of intermodal transportation projects. The major tenet of the study is that in the development of an intermodal project evaluation methodology for the freight sector, public agencies must necessarily incorporate the significant differences in social costs among modes. This study examines various theoretical and empirical issues involved in estimating social costs and benefits of intermodal projects combining various modal options.
