BREAKAWAY LIGHTING COLUMNS DEVELOPED BY R.R.L.

THE MINISTRY OF TRANSPORT IS TO INSTALL A NEW TYPE OF 'BREAKAWAY' LIGHTING COLUMS ON A 3 1/2-MILE STRETCH OF THE GREAT NORTH ROAD, TO THE NORTH OF THE DONCASTER BY-PASS. THE COLUMN, WHICH WAS DEVELOPED BY THE ROAD RESEARCH LABORATORY, IS OF LIGHTWEIGHT STEEL WITH A BREAKABLE JOINT JUST ABOVE GROUND LEVEL. EVIDENCE OF TRIALS SHOW THAT COLUMNS SITED BEYOND THE NEARSIDE EDGE OF THE CARRIAGEAWAY ARE UNLIKELY TO FALL INTO THE ROAD, AND THAT IF THEY DID SERIOUS ACCIDENTS CAUSED THEREBY WOULD BE IMPROBABLE. OF AN INSTALLATION OF 11 SUCH COLUMNS IN USE ON PUBLIC ROADS SINCE NOVEMBER, 1964, ONE HAS BEEN HIT BY A BUS. THERE WERE NO INJURIES, DAMAGE TO THE BUS WAS SLIGHT, AND THE COLUMN FELL ON A TRAFFIC ISLAND. THE DESIGN OF THE COLUMN IS ILLUSTRATED AND BRIEFLY DESCRIBED. /RRL/
