DRIVER INFORMATION REQUIREMENTS, DISPLAY CONCEPTS, AND ACCEPTANCE FACTORS FOR AN ELECTRONIC ROUTE GUIDANCE SYSTEM

THE PURPOSE WAS TO ANALYZE THE ROUTE GUIDANCE INFORMATION REQUIRED AND PREFERRED BY DRIVERS. REQUIRED DRIVER INFORMATION WAS DERIVED BY DETERMINING HOW A FAMILIAR 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 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. DRIVERS INFORMATION WAS ESTABLISHED FOR (1) APPROACH PATHS, (2) CHOICE POINTS, (3) TARGET PATHS AND (4) CLOSE SEQUENTIAL CHOICE POINTS. LITERATURE ON HUMAN CAPABILITIES AND LIMITATIONS WAS REVIEWED TO DEVELOP DISPLAY OF THE ERGS CONCEPT, INFORMATION REQUIREMENTS, DISPLAY CHARACTERISTICS AND DESIRABILITY OF A PARTIALLY IMPLEMENTED SYSTEM WAS ALSO ANALYSED. REPRESENTATIVE COMPLEX ROUTE GUIDANCE PROBLEMS TOGETHER WITH VARIATIONS IN THE DRIVER INFORMATION REQUIREMENTS AND DISPLAY CONCEPTS WERE PRESENTED TO DRIVERS. THE DRIVERS INDICATED (1) HOW THEY WOULD PERFORM WITH THE DISPLAYED INFORMATION AND (2) WHICH OF THE DISPLAYED INFORMATION CONCEPTS THEY PREFERRED. 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/
