HIGHWAY ADVISORY RADIO

The background of highway advisory radio(HAR) and some of the considerations that led to the present rules are discussed. The effect on HAR system design of limitations imposed by the rules and by receiver characteristics is also discussed. Using field data the problems of HAR antenna design within the FCC imposed limits are illustrated. Finally, the FCC "Part 15" alternative to the design of HAR systems is discussed. Conclusions are stated. The general conclusion drawn is that HAR can be, and has repeatedly proven to have been, a useful tool for traffic management and control.
