A PRELIMINARY ANALYTICAL INVESTIGATION OF THE BRIG ROAD SAFETY EDGE CONCEPT

THE BRIG ROAD SAFETY EDGE IS A DEPRESSED EDGE BETWEEN THE PAVEMENT AND THE ROADSIDE SHOULDER . THIS ANALYTICAL STUDY APPLIES A COMPUTER SIMULATION OF THE DYNAMICS OF SINGLE VEHICLE ACCIDENTS IN A PRELIMINARY EVALUATION OF THE BRIG CONEPT. DUE TO THE TIME PERIOD AVAILABLE, THE INVESTIGATION WAS LIMITED IN THE NUMBER OF SIMULATION RUNS; FOUR WERE MADE FOR COMPARISON PURPOSES SIMULATING CONTACTS WITH A CONVENTIONAL CURB. DEVINITIONS ARE GIVEN OF THE REQUIRED PROGRAM MODIFICATIONS AND EXTENSIONS TO INCORPORATE GYROSCOPIC EFFECTS. IT IS CONCLUDED THAT THE PROPOSED BRIG ROAD EDGE WILL PRODUCE CORRECTIVE STEER EFFECTS ONLY UNDER EXTREMELY LIMITED CONDITIONS OF DEPARTURE FROM THE PAVEMENT AND THAT THE MECHANISM THROUGH WHICH THE EFFECTS ARE PRODUCED DIFFERS SUBSTANTIALLY FROM THAT DESCRIBED IN THE U. S. PATENT AND IN AN EARLIER ANALYSIS SUPPORTING THE PATENT CLAIMS. /FHWA/
