A less strict form of influencing driving behavior is offered by Information Systems. General systems are of the broadcasting type, the information they give is the same for everybody. Some countries value the impact these information services have sufficiently high to justify a public funding. Tailor-made information services will be private everywhere. For automated control a direct link from the roadside to the vehicle will be needed.
Beacons offer the most feasible solution.
These beacons can also be used to obtain information from vehicles, like information on road surface conditions. Vehicles may also use cellular or satellite communications. Both to obtain tailor-made information or to send messages. Tailor-made information may be a whole package including traffic, weather, hotel and airline schedule information. For this package information the best source for traffic information is the Management Center.
