RUMBLE STRIP EXPERIMENTS ON A FREEWAY RAMP

A METHOD WAS DEVISED BY THE MICHIGAN DEPARTMENT OF STATE HIGHWAY TRAFFIC ENGINEERS TO WARN MOTORISTS TRAVELLING ON AN INTERSTATE LIMITED ACCESS HIGHWAY FROM THE OHIO BORDER, OF THE CHANGING HIGHWAY ENVIRONMENT, NAMELY THE END OF THE FREEWAY. TO BREAK THE HIGHWAY HYPONSIS THAT OFTEN FOGS A DRIVERS MIND TO ADVANCE SIGNING, RUMBLE STRIPS, RAISED BITUMINOUS STRIPS, WERE PLACED IN ADVANCE OF THE MERGE OF THE TWO ROADWAYS. MACADAM MATS WERE ALSO PLACED IN A TEST AREA TO DETERMINE THEIR EFFECTIVENESS. EFFECTS OF THE ROUTED MACADAM MATS ALERTED THE MOTORIST, BUT THEY DID NOT UNIFORMLY REDUCE SPEED. THE STONE RUMBLE STRIPS APPEARED TO HAVE DEFINITE VALUE SINCE THEY ALERTED AND STIMULATED THE DRIVER BY BOTH TACTILE AND AUDIBLE MEANS TO EXERCISE THE DRIVING SKILL NECESSARY TO NEGOTIATE THE CHANGING HIGHWAY CONDITIONS.
