USE AND DESIGN OF ACCELERATION AND DECELERATION LANES IN INDIANA

THE SPEED AND LATERAL PLACEMENT OF VEHICLES ON THE VARIOUS DESIGNS OF THE ACCELERATION AND DECELERATION LANES OF THE INDIANA TOLL ROAD AND THE INTERSTATE SYSTEM OF THE STATE OF INDIANA WERE STUDIED TO CORRELATE THE ACCELERATION AND LANE DESIGN WITH TRAFFIC BEHAVIOR AND DRIVER REQUIREMENTS AND TO DETERMINE WHICH ACCELERATION AND DECELERATION LANE DESIGNS PROVIDE THE MOST EFFICIENT AND SAFEST OPERATION. DATA ON SPEEDS AND LATERAL PLACEMENT OF TRAFFIC USING THE ACCELERATION AND DECELERATION LANES WERE OBTAINED BY USE OF A MOTION PICTURE TECHNIQUE. SPOT SPEEDS OF THROUGH LANE TRAFFIC WERE MEASURED USING AN ELECTROMATIC RADAR SPEED METER. THE STUDY REVEALED THAT A LARGE NUMBER OF THE DRIVING PUBLIC DO NOT KNOW HOW TO USE ACCELERATION AND DECELERATION LANES PROPERLY. ACCELERATION OR DECELERATION LANE TRAFFIC WAS FOUND TO HAVE LITTLE EFFECT ON THE SPEED OF THE THROUGH LANES BEFORE DIVERGING INTO THE DECELERATION LANES. THE LONG DIRECT TAPER TYPE OF DESIGN WAS FOUND SUPERIOR FOR BOTH ACCELERATION AND DECELERATION LANES. /AUTHOR/
