HUMAN FACTORS REQUIREMENTS FOR REAL-TIME MOTORIST INFORMATION DISPLAYS. VOLUME 13. HUMAN FACTORS EVALUATION OF AUDIO AND MIXED MODAL VARIABLES
The document summarizes fifteen research studies dealing with techniques for improving low-powered radio communications and the interface between radio and visual signing modes of communication. Studies were conducted both in laboratory and in-situ research vehicles. Topics investigated were language style of radio messages; the effects of order of message elements and message load on recall of specific elements; the types of route-following errors committed with internally and successively redundant audio messages; the effects of the complexity of a diversion route on success in route following from radio instructions; a comparison of success in route following with visually-coded trail blazers and with radio route guidance; the message design of an advance road sign to direct drivers to tune their radios for traffic information; and a survey of descriptors employed by local residents in describing to visitors a diversion route around an incident.
