MORE STREET LIGHTS BEING INSTALLED
** ** ** ** 28
MORE STREET LIGHTS ARE BEING INSTALLED TO IMPROVE ROAD TRAFFIC SAFETY AS WELL AS PUBLIC SECURITY.
BETWEEN APRIL AND JUNE THIS YEAR, SOME 400 NEW STREET LIGHTS HAVE BEEN INSTALLED 120 ON HONG KONG ISLAND, 85 IN KOWLOON AND 200 IN THE NEW TERRITORIES.
PLANS ARE IN HAND TO INSTALL ANOTHER 700 STREET LAMPS IN KOWLOON AND THE NEW TERRITORIES, AND SOME 400 ON HONG KONG ISLAND.
AT PRESENT THERE ARE ABOUT 25,000 STREET LAMPS THROUGHOUT HONG KONG.
MEANWHILE, SPECIAL MEASURES ARE BEING IMPLEMENTED TO IMPROVE THE STANDARD OF LIGHTING. A SPOKESMAN FOR THE PUBLIC WORKS DEPARTMENT SAID A NEW TECHNIQUE, KNOWN AS HIGH MAST LIGHTING, WAS BEING INTRODUCED.
+THIS IS A MORE EFFECTIVE TYPE OF LIGHTING IN ILLUMINATING. COMPLICATED INTERSECTIONS WHERE A HIGHER LEVEL OF ILLUMINATION IS REQUIRED TO ENABLE MOTORISTS TO PICK OUT THEIR ROUTE SAFELY AND UNMISTAKABLY IN HEAVY TRAFFIC AND IN BAD WEATHER,+ HE EXPLAINED.
IT INVOLVES THE USE OF CLUSTERS OF POWERFUL LIGHTS
SUSPENDED FROM MASTS UP TO 100 FEET ABOVE THE ROAD SURFACE. THE NORMAL HEIGHT FOR THE MOUNTING OF CONVENTIONAL STREET LIGHTING IN HONG KONG VARIES BETWEEN 15 TO 35 FEET.
+HIGH MAST LIGHTING HAS ALREADY BEENUSED AT PIPER HILL AND CHOI HUNG INTERCHANGES, THE SPOKESMAN SAID. +AND IT IS EXPECTED THAT SUCH LIGHTING TECHNIQUE WILL BE APPLIED TO THE PROPOSED WIDENING OF THE TOLL PLAZA FOR THE SECOND LION ROCK TUNNEL AND TO SOME MULTI-LEVEL INTERCHANGES IN FUTURE.+
LOW PRESSURE SODIUM LAMPS, WHICH HAVE BEEN WIDELY USED IN RURAL AREAS, ARE ALSO BEING INSTALLED AT MAJOR TRAFFIC ROUTES IN URBAN AREAS.
THESE LAMPS, WHICH PRODUCE A YELLOWISH LIGHT, HAVE LONG BEEN THE MOST EFFICIENT LIGHT SOURCES WITH RELATIVELY LESS GLARE. +SODIUM LIGHTS ARE ALSO BEING INSTALLED IN AREAS WHICH ARE OVER 500 FEET ABOVE SEA LEVEL BECAUSE OF THEIR EFFECTIVELESS EVEN IN MISTY WEATHER,+ THE SPOKESHAN SAID.
