DRIVER INFORMATION REQUIREMENTS AND ACCEPTANCE CRITERIA

THE ELECTRONIC GUIDANCE SYSTEM (ERGS) INFORMATION REQUIRED AND PREFERRED BY DRIVERS WAS ANALYZED. REQUIRED DRIVER INFORMATION WAS DERIVED BY DETERMINING HOW AN UNFAMILIAR DRIVER NEGOTIATED A GENERIC INTERSECTION. THE GENERIC INTERSECTION WAS DEFINED IN TERMS OF (1) CHOICE POINTS, (2) CHARACTERISTICS OF THE APPROACH TO THE CHOICE POINT, AND (3) CHARACTERISTICS OF EXIT PATHS. A DRIVER'S TASK ANALYSIS WAS PERFORMED TO OBTAIN ESTIMATES OF TIME AND INFORMATION REQUIRED TO NEGOTIATE COMPLEX INTERSECTIONS. THIS ENABLED A DETERMINATION OF DRIVER INFORMATION REQUIREMENTS DIRECTLY, FROM THE STEP-BY-STEP TASK ANALYSIS, AND INDIRECTLY, FROM THE ESTIMATES OF INFORMATION LEAD DISTANCE REQUIREMENTS. DRIVER INFORMATION WAS ESTABLISHED FOR APPROACH PATHS, CHOICE POINTS, TARGET PATHS, AND CLOSE SEQUENTIAL CHOICE POINTS. LITERATURE ON HUMAN CAPABILITIES AND LIMITATIONS WAS REVIEWED TO DEVELOP DISPLAY CONCEPTS APPROPRIATE FOR A WIDE SPECTRUM OF THE DRIVER POPULATION. DRIVER ACCEPTANCE OF THE ERGS CONCEPT, INFORMATION REQUIREMENTS, DISPLAY CHARACTERISTICS, AND DESIRABILITY OF A PARTIALLY IMPLEMENTED SYSTEM WAS ALSO ANALYZED. REPRESENTATIVE COMPLEX ROUTE GUIDANCE PROBLEMS TOGETHER WITH VARIATIONS IN THE DRIVER INFORMATION REQUIREMENTS AND DISPLAY CONCEPTS WERE PRESENTED TO DRIVERS. THE DRIVERS INDICATED HOW THEY WOULD PERFORM WITH THE DISPLAYED INFORMATION, AND WHICH OF THE DISPLAYED INFORMATION CONCEPTS THEY PREFERRED. FINALLY, INFORMATION ON DRIVER'S PREFERENCE FOR IMPLEMENTING THE SYSTEM ON PRIMARY ROADS, IN CENTRAL BUSINESS DISTRICTS, AT CRITICAL INTERSECTIONS, OR IN SUBURBAN AREAS WAS DETERMINED. /AUTHOR/
