A model describing the development of road freight transport.

In an ongoing cooporation between Statistics Denmark and NERI we are developing a satellite model to a Danish macroeconomic model ADAM. That is a model linked to the macroecenomic development in ADAM, deriving the freight transport demand on Danish roads and energy consumption from this. A first operational version of the model is now ready. In the paper an overall view of the model is given, with simple calculation examples. A general discussion of the possible developments of the model into a dynamical model is given with focus on a specific area of the model.

丹麦统计局（Statistics Denmark）与NERI正在开展合作，为丹麦宏观经济模型ADAM开发一个卫星模型（satellite model）。该模型与ADAM中的宏观经济发展动态相关联，可据此推导丹麦道路的货运需求及能源消耗情况。目前，该模型的首个可运行版本已准备就绪。论文中给出了该模型的整体概述，并辅以简单的计算示例。此外，本文还针对模型向动态模型（dynamical model）的潜在发展方向展开了一般性讨论，重点聚焦于模型的某一特定领域。
