To promote maritime coastal container feeder and modal shift we developed an evaluation method of measures and policies for unit load land and sea intermodal transportation. The method uses generalized cost model expanded with correction terms (residual generalized cost terms) to estimate cargo transportation route. Its origin-destination mesh of domestic cargo has 207 livelihood spheres and its transportation model doesn't abbreviate any coastal sea routes and ports which appear in targeted cargo history data. By calibrating the correction terms semi-automatically the system achieved highly accurate transportation reproduction although the simulation model is precise. This paper describes the above method and shows the analysis result of coastal cargo incentive policy as an example problem.
