Hanysz, E., "A Communication System for Driver Aid, Information, and Routing," SAE Technical Paper 670111, 1967, doi:10.4271/670111.
A new concept in communications for the motorist called DAIR for Driver Aid, Information, and Routing is described. It is designed to assist the driver with his peripheral functions so that he can concentrate his attention on driving. DAIR automatically gives routing instructions, communicates traffic signs and roadside messages, and provides a radio link to call for emergency assistance or information.The system is cooperative between the motorist and the road authority but is independent of other motorists. Demonstration hardware has been designed around the Citizens Band to take advantage of the mobile transceivers already in service. DAIR can be implemented in a building block fashion using the CB transceiver as the basic component.
