The Virginia Department of Highways and Transportation utilized an advisory radio to advise motorists of possible delays caused by resurfacing operations on a major interstate highway and to give information concerning the use of an available detour. This report describes an evaluation of the effectiveness of the radio unit on the basis of the use made of the radio messages by motorists and the effect of the messages on traffic flow through the maintenance area and available detour. The results of traffic counts, time delay runs, and a motorist survey indicated that the unit used was not fully effective because of the inability of motorists to tune in the frequency or to hear or understand the message; however, it is felt that the concept of the highway advisory radio has good potential as a source of information and possible aid to motorists.
