DEVELOPMENT OF AN EFFECTIVE RUMBLE STRIP PATTERN
TWO TYPES OF RUMBLE DEVICES, USED TO DIRECT IN ADVANCE THE ATTENTION OF MOTORISTS TO UNUSUAL TRAFFIC CONDITIONS, ARE CONSIDERED: THE RUMBLE STRIP, A SECTION OF MATERIAL WHOSE CROSS-SECTION IS USUALLY NOT GREATER THAN ONE INCH IN HEIGHT AND SEVERAL INCHES IN WIDTH, SPANNING THE WIDTH OF THE ROADWAY, AND THE RUMBLE AREA, A TOPPING SURFACE SPANNING THE ROADWAY AND RUNNING UPWARDS OF 25 FEET IN LENGTH. TESTS WERE CONDUCTED TO DETERMINE WHICH OF THE TWO TYPES SHOULD BE EMPLOYED, THE DEGREE OR AMOUNT OF DISTURBANCE NECESSARY TO GENERATE THE BEST WARNING, THE TYPE OF PATTERN NEEDED TO PRODUCE THE DISTURBANCE, AND THE TYPES OF MATERIAL AND METHOD OF APPLICATION TO BE USED TO PROVIDE A SERVICEABLE INSTALLATION. BASED ON THE RESULTS OF THESE EXPERIMENTAL TESTS IT WAS CONCLUDED THAT THE RUMBLE STRIP WAS MORE EFFECTIVE, BOTH FROM A MAINTENANCE AND WARNING CONSIDERATION. A FIELD TEST WAS THEN CONDUCTED ON A RUMBLE STRIP PATTERN WHICH WAS INSTALLED AT A SITE CARRYING A GOOD VARIETY OF TRAFFIC. TIME AND USAGE AT THE FIELD SITE INDICATE THAT THE QUALITY OF THE MATERIALS, THEIR PROPORTIONS, THE METHOD OF COMBINING, AND THE PROCEDURE FOR PLACING THEM PRODUCED A HIGH QUALITY INSTALLATION WHICH WAS QUICKLY INSTALLED, PROVIDED A MINIMUM OF TRAFFIC DISTORTION, AND RESISTED WEAR, WEATHER, AND UNUSUAL TREATMENT. DATA ALSO INDICATED THAT THE RUMBLE STRIP PATTERN AND INSTALLATION WERE MAKING A REAL CONTRIBUTION TOWARD REDUCING THE ACCIDENT RATE.
