Generally it can be found that they have reached a high level in Switzerland passenger transport models. Improvements consists principally in passenger traffic models for regions, conurbations and municipalities, where the reliability of the model results and the consideration of inter-modality in terms of the assessment of transport policies must be significantly improved.

Based on this finding, the Association of Swiss Transport Engineers has provided in its multiannual program, several research projects on transport models. In a preliminary study, this list should be supplemented and corrected in cooperation with traffic modeling actors in federal offices, cantonal and communal administrations and the universities into a coherent research program. It is clarified that the form of a coordinated processing of these projects with regard to the use of synergies and the know-how mediation is better suited to the practice.
