DEVELOPMENT OF INFORMATION REQUIREMENTS AND TRANSMISSION TECHNIQUES FOR HIGHWAY USERS
THE DRIVER IS SEEN AS AN INFORMATION PROCESSOR THAT IS RECEIVING---OR NOT RECEIVING---INFORMATION FROM AND ABOUT A SYSTEM CONSISTING OF VEHICLE, ROAD, AND ENVIRONMENT. THE DRIVING TASK IS DIVIDED INTO A TRIPARTITE HIERARCHY, WITH TRACKING AND SPEED CONTROL (CALLED MICROPERFORMANCE) AT ONE END, SITUATIONAL RESPONSE IN THE MIDDLE, AND DIRECTION- FINDING AND TRIP PLANNING (CALLED MACROPERFORMANCE) AT THE OTHER END. MICROPERFORMANCE NEEDS HAVE PRIORITY OVER THE OTHERS. THE DRIVER APPROACHES HIS TRIP WITH CERTAIN EXPECTATIONS ABOUT THE INFORMATION THAT THE ROAD WILL SUPPLY HIM. USING ACTUAL SECTIONS OF INTERSTATE AND RURAL ARTERIAL HIGHWAYS, AIRBORNE INSTRUMENTS LABORATORY DEVELOPED A PROCEDURE FOR SYSTEMATIC APPLICATION OF PERTINENT HUMAN FACTORS PRINCIPLES TO THE REVIEW OF HIGHWAY INFORMATION SYSTEM DESIGN. IT WAS FOUND THAT SIGNS SHOULD CONTINUE TO BE THE MAIN INFORMATION CARRIERS. SPECIAL ATTENTION WAS GIVEN TO DESIGN OF SIGNS FOR NIGHT LEGIBILITY. IMPROVEMENTS TO MAPS FOR MACROPERFORMANCE NEEDS ARE SUGGESTED. THE PROCEDURE FOR APPLYING HUMAN FACTORS PRINCIPLES IS FORMALIZED IN ONE OF THE APPENDICES, ENTITLED "NOTES FOR A MANUAL ON INFORMATION SYSTEM REVIEW PROCEDURES."
