== Abstract ==

dvanced Traveler Information Systems, which have for long been regarded as one of the most promising future applications of wireless vehicular networks for use in the ﬁeld of Intelligent Transportation Systems (ITS), are eﬀectively becoming part of today’s reality. Many drivers already access the information provided by such systems, for example checking for the state of the streets along a given route or reading traﬃc jam alerts on the displays of smart-phones or Personal Navigation Devices (PNDs). Based on such information, drivers, or their PNDs, select the best paths to reach their destinations. Clearly, in order to be eﬀective, such systems are required to reliably estimate and forecast vehicular congestion states. Moreover, they should also be capable of eﬃciently utilizing the wireless channel resources, as the amount of information that may be exchanged by such systems in dense urban areas grows with the number of services supported by the onboard devices and the amount of vehicles that install them. To answer these challenges, we here discuss how a distributed ATIS can: a) implement an eﬀective vehicular congestion detection and forecasting model, and, b) eﬃciently disseminate traﬃc information. The advantage of distributing an ATIS is that each vehicle can compute and redistribute accurate vehicular congestion information very rapidly, with little overhead and without resorting to a central entity. In order to validate our approach, we present the outcomes of a real world experimentation, as well as of multiple simulations.
