FOG FLASHER AIDS WESTERN HIGHWAY USERS

AN INFRARED SENSING AND CONTROL SYSTEM THAT DETECTS FOG HAS BEEN SET UP ON A COLORADO HIGHWAY TO WARN DRIVERS WHEN HAZARDOUS CONDITIONS HAVE SET IN. THE FOG---WHICH IS CAUSED BY A COMBINATION OF STEAM BY A NEARBY PROCESSING PLANT, MIST FROM THE SOUTH PLATTE RIVER, AND TEMPERATURE INVERSIONS---CAN SETTLE IN ON THE ROAD WITHOUT WARNING AND REMAIN THERE OVER SEVERAL HUNDRED FEET OF ROADWAY, EVEN THOUGH APPROACHES ARE CLEAR. A NETWORK OF SIX SENSORS HAS BEEN PLACED ALONG A HALF-MILE SECTION OF INTERSTATE 805 AT FORT MORGAN AND REACTS WHEN FOG SETS IN. AS VISIBILITY IS REDUCED TO LESS THAN 1,000 FT AT ONE OR MORE OF THE SENSORS, FLASHING WARNING SIGNS ARE ACTIVATED ON EITHER SIDE OF THE AREA. /ARTICLE/
