The development of multimodal transport terminals in urban areas generates various serious environmental problems. The available tools for the analyses of the use of such terminals offer insufficient support for decision-making on the location and design of these terminals from the sustainability perspective. New approaches are needed. This article contributes to satisfy this need, triggered by the planning of a new Barge Terminal in the Dutch city of Tilburg (BTT). Presently, the existing terminal in Tilburg is operating near full capacity and the construction of a new terminal is considered the best strategy to cope with steady growth. The main question concerns the optimal design of the new barge terminal to offer a high operational performance, however without exceeding the environmental quality standards, in particular noise. The article presents a simulation approach to assist in the process of finding a balance between the operational performance and the noise effects of alternative designs of the new terminal.
