The TRIMODE integrated model for Europe combines the simulation of transport, economy and energy systems for the assessment of major transport infrastructure projects and policies. Within a single software platform, the model components include a full four stage Transport model of passenger and freight movements, an Energy model with dynamic vehicle fleets for all transport modes and an Economy model representing the complete macroeconomic system of European countries with a two-layer General Equilibrium model that works at both a regional and a national level. Covering the whole European Union and it neighbouring countries, the model has a very detailed spatial resolution of the transport system, with a NUTS III level multimodal network, coupled with detailed disaggregation of transport demand by socio-economic groups, purposes, etc. for passengers and by NST and handling categories, etc. for freight. The model considers all types of energy sources and technologies for all modes of transport.
