Current situation and systems under development
Current situation:
Until recently, the primary interaction between vehicles and roadways has been the interface between the tire and road surface at the tire contact patch
In addition, loop detectors, roadside closed-circuit cameras, microwave radar or roadway weather information services provide data about, and in some instances (e.g., variable message signs) to vehiclesinformation services provide data about, and in some instances (e.g., variable message signs) to vehicles
Most widely spread technology to deliver traffic and travel information to vehicles is the Traffic Message Channel (TMC), mainly transmitted via FM. When data is integrated directly into a navigation systems, this gives the driver the option to take alternative routes to avoid traffic incidents.
Systems under development include:Traffic control and management systems
Intersection collision warning applications
Weather and road condition warning systems

Route guidance to avoid traffic congestion and, consequently, wasting fuel
as well as information tools, e.g. advice on the location of nearby car parks with available parking spaces
