CarbonRoadMap : a multicriteria decision tool for multimodal transportation

This article proposes a multicriteria approach and a decision support system to support multimodal transportation planning decisions by considering transportation delay, costs, and carbon emissions. The methodology is implemented into CarbonRoadMap, a web-based application that allows a decision maker to browse through the set of Pareto-optimal paths, display them on a map to support the selection of the desired optimum solution by weighting the three criteria. This decision support tool shows the benefits of using a multicriteria optimization methodology to obtain a set of paths, as the resulting solutions are very different from one another. A case study is provided for forest product distribution in North America.
