Transport module (TRA)

The matrices estimated in the REM module are the major input of the Transport Module (TRA).

Using transport cost and transport time matrices the transport module performs the modal-split for five passenger modes and three freight modes. The cost and time matrices depend on influencing factors like infrastructure capacity and travel speeds both coming from the INF module, structure of vehicle fleets, transport charges, fuel price or fuel tax changes. Depending on the modal choices, transport expenditures are calculated and provided to the macroeconomics module. Changes in transport times are also transferred to the macroeconomics module such that they can influence total factor productivity. Considering load factors and occupancy rates respectively, vehicle-km are calculated.
