An urban transportation network integrating public and private modes of transport is modelled as a Discrete Event System. The behaviour of the model adopted is reproduced by means of a traffic simulator designed on purpose. This paper centres around the functioning of the on-line information service included in the simulator, which is able to provide updated information about the best intermodal paths to reach any destination in the network. Such best paths vary according to the system dynamics, depending essentially on the traffic conditions. Examples of application of the special algorithm implemented to find the best multimodal paths are presented.
