Intervehicle communications for higher safety and higher efficiency at intersections

New technologies in vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) are now being developed for numerous applications. One key application is the improvement of safety at intersections. It is in particular the scope of the Intersafe-2 European Project. We can also use V2V and V2I for the improvement of efficiency at intersections if we can reduce the number of stops at intersections through a good cooperation between different flows of vehicles. At the same time we also want to maximize the throughput at the intersections. This problem has been studied for the operation of fully automatic vehicles such as those we find in current PRT, during the European project CyberCars-2 with interesting results.
