SHORT TUNNELS

FROM THE LIGHTING POINT OF VIEW A SHORT TUNNEL IS DESCRIBED AS ONE OF WHICH THE EXIT CAN BE SEEN, DURING THE DAY AND WITH NO TRAFFIC, FROM A POINT AT SOME DISTANCE FROM THE TUNNEL ENTRANCE, AND OF WHICH THE EXIT THEN OCCUPIES A SUFFICIENTLY LARGE PART OF THE FIELD OF VISION TO MAKE OBSTACLES IN THE TUNNEL STAND OUT AGAINST IT. IN REVIEWING THE LIGHTING OF SHORT TUNNELS, THE QUESTION AS TO WHICH OF THESE COULD REMAIN UNLIT IS CONSIDERED. THE FORM OF LIGHTING TO BE APPLIED FOR THE OTHERS IS THEN DISCUSSED. A TABLE SHOWS LIGHTING SYSTEMS RECOMMENDED FOR SHORT TUNNELS. /RRL/
