We demonstrate the impact, both positive and negative, of a dynamic vehicle re-routing mechanism that is based on real-time traffic information. For this, we employ a simulative prototype implementing a Traffic Information System (TIS) operating in an urban setting. The simulative prototype can be interacted with in real time to manually introduce traffic obstructions in the running simulation. The effects of these obstructions and the impact of dynamic vehicle re-routing can then be observed. In particular, we integrated the Adaptive Traffic Beacon (ATB) protocol within our Vehicles in Network Simulation (Veins) framework. Vehicles use ATB to continuously exchange part of their knowledge bases in the form of periodical beacons, the interval of which is dynamically adapting to the estimated usefulness of information and to channel conditions. This way, the average channel utilization is continuously optimized, and over-use avoided, at all times.
