Two reports on variables related to highway advisory radio are presented. In one study, warning material in short, staccato messages was compared to warning material in long, detailed messages. The long, detailed messages were retained consistently better than the short, staccato ones. The second experiment investigated the effect of route numbers as directions in navigation messages on message retention. The results indicate conclusively that as the frequency of route numbers in messages increases, the frequency of route errors increases. In both experiments, the material was presented visually as well as aurally.

The subjects sat in a driving simulator and watched a motion of a construction work area that was taken through the windshield of an automobile as the subjects "drove." Simulated radio messages were given that described the features of the work area. Subjects had to indicate their preference between a longer detailed message and a shorter general message format. The messages were presented at three different times before the construction area on the film began. A questionnaire was used to elicit the responses from the subjects.
