Assessment of direct and indirect transport network effects. Transport network effects are distinguished into direct and indirect network effects. The direct network effects are measured by a standard 4-step transport model. The indirect network effects are measured by using a macro-economic model. The output of this model is fed back into the transport model. Combining a transport model and a macro-economic model is the main feature of a methodology to assess both direct and indirect transport network effects. The methodology has been tested on 3 TEN-T corridors. The conclusion is that combining a standard transport model with a general equilibrium model works well to assess both direct and indirect network effects. The results for the 3 corridors show minor indirect transport network effects. At the level of the entire TEN-T the effects of the different corridors can be added up. However, this is not the case on OD-relations. The general conclusion is that indirect transport network effects cannot be neglected. (Author/publisher)
