This chapter is, to a large extent, based on a series of projects carried out for the Work Group for Transport Analysis in the Norwegian national transport plan, the Samgods group in Sweden, the Government of the Flanders region in Belgium and the Technical University of Denmark (DTU). Organizations that were involved in these projects include Significance, RAND Europe, SITMA, IMOB University Hasselt, DTU, Solving International, Solving Bohlin & Strömberg, and INRO Canada. The authors would like to thank Inge Vierth of VTI/CTS for comments on an earlier version.
