CRITERIA FOR DESIGN AND DEPLOYMENT OF ADVANCED GRAPHIC GUIDE SIGNS

THIS STUDY WAS DESIGNED TO DETERMINE THE GRAPHIC SIGN CHARACTERISTICS THAT BEST COMMUNICATED ROADWAY- INTERCHANGE AND ROUTE-GUIDANCE INFORMATION TO THE DRIVER. EMPHASIS WAS PLACED ON (A) DEVELOPING LABORATORY SIGN-TESTING PROCEDURES FOR DETERMINING THE EFFECTIVENESS OF SIGNING ALTERNATIVES AND (B) DEVELOPING ANALYTICAL TECHNIQUES FOR IDENTIFYING INTERCHANGE CHARACTERISTICS WHERE GRAPHIC GUIDE SIGNS MIGHT BE REQUIRED AND APPLICABLE. IN THE LABORATORY SIGN-TESTING PROCEDURE, ONE 35-MM SLIDE PROJECTOR SHOWED A ROADWAY SCENE IN WHICH THE GUIDE SIGNS WERE BLACKED OUT AND ANOTHER PROJECTOR SHOWED A SCALE- MODEL TEST SIGN IN THE BLACKED-OUT AREA FOR 1 SEC. CHARACTERISTICS OF INTERCHANGES WHERE GRAPHIC GUIDE SIGNS SHOULD BE CONSIDERED WERE IDENTIFIED BY THEORETICAL ANALYSES. LABORATORY TESTS INDICATED THAT ROUTE-GUIDANCE WAS PROVIDED SIGNIFICANTLY BETTER BY GRAPHIC SIGNS THAN BY CONVENTIONAL SIGNS ON CERTAIN INTERCHANGES. GRAPHIC SIGNS ALSO CONVEY RELATIVE EXIT SPEEDS AND LANE-DROP INFORMATION EFFECTIVELY.
