FREEWAY RAMP CONTROL REDUCES FREQUENCY OF REAR END ACCIDENTS

THE PRIMARY OBJECTIVE OF THIS STUDY WAS TO INVESTIGATE THE ACCIDENT FREQUENCY ON THE INBOUND SECTION OF THE GULF FREEWAY BEFORE THE ENTRANCE RAMPS WERE CONTROLLED AND THEN EVALUATE THE EFFECTIVENESS OF RAMP CONTROL IN REDUCING THE FREQUENCY OF REAR-END ACCIDENTS AS A RESULT OF THE IMPROVED LEVEL OF SERVICE ON THE FACILITY. ONLY REAR-END ACCIDENTS OCCURRING ON WEEKDAYS BETWEEN THE HOURS OF 7'00 A.M. AND 9'00 A.M. WERE CONSIDERED. ACCIDENT LOCATIONS WERE CLASSIFIED AS EITHER FREEWAY, RAMP, OR FRONTAGE ROAD. REAR- END ACCIDENTS WERE SUBSTANTIALLY REDUCED AFTER THE RAMP CONTROL WAS INITIATED. THIS WAS ESPECIALLY TRUE AT ON-RAMPS AS NO REAR-END ACCIDENTS OCCURRED AT THESE LOCATIONS AFTER RAMP CONTROL WAS BEGUN. ALL REAR-END COLLISIONS ON THE SIX MILE FREEWAY WERE REDUCED BY APPROXIMATELY 50 PERCENT AFTER RAMP CONTROL WAS BEGUN. /BPR/
