Final Briefing of a study performed for the Directorate-General of Freight Transport (DGG) of the Dutch Ministry of Transport, Public Works and Water Management, called ''Improving the Policy Relevance of Freight Transport Models''. The study involved two tracks; firstly to examine the information needs of policy makers at DGG, and secondly to gather information provided by existing freight transport models available through the Ministry's Transport Research Centre. Needs were identified through interviews and a workshop, and information about available freight transport models was gathered using a questionnaire. The Final Briefing contains four parts, the first part of which contains a general project description. It contains information about all of the models used, covering strengths, modes covered and time frames. The second and third parts contain overviews of workshops involving the policy makers and modellers, which paralleled the two tracks of the study. Finally, the fourth concluding part outlines four tasks to be carried out in order to satisfy the objectives of the overall project. This study is the first phase of multi-phase project for the current and anticipated future information needs of DGG policymakers.
