Bi-modal traffic system including an integrated path network for bi-modal vehicles, especially for bi-modal trucks, wherein the bi-modal vehicles are configured so that they run both on rail tracks as well as on road tracks. The integrated path network includes at least one rail network and one road network, wherein the at least one rail network and the at least one road network are coupled by at least one junction. The at least one junction is configured so that bi-modal vehicles may change from rail network to a road network and may adapt their speed so that a change of a bi-modal vehicle from the rail network into the road network does not impair the ongoing traffic on the road network, and/or is configured so that bi-modal vehicles may change from a road network to a rail network and may adapt their speed so that a change of a bi-modal vehicle from the road network into the rail network does not impair the ongoing traffic on the rail network.
