THE SHORTCOMINGS OF THE WIDELY USED BURIED-LOOP VEHICLE DE- TECTOR -- 3 TO 5 YEAR LIFETIME, COSTLY, INCONVENIENT TO MAINTAIN/REPLE, INCOMPATIBLE WITH SOME ROADWAYS, UNRELIABLE ACTIVATION BY SOME VEHICLES -- CAN BE OVERCOME THROUGH THE USE OF OVERHEAD INFRARED VEHICLE DETECTORS. THE TECHNICAL OBJECTIVES OF THE PROPOSED RESEARCH INCLUDE A SURVEY OF APPROPRIATE INFRARED SENSORS AND DEVICE ANALYSIS, D ...

THE DEPARTMENT OF TRANSPORTATION (DOT) IS REQUIRED TO MAIN- TAIN THE NATION'S BRIDGES AND ENSURE THEIR SAFETY. HOWEVER,A LARGE NUMBER OF BRIDGES HAVE NOT BEEN RECENTLY INSPECTED TO DETERMINE IF THEY ARE CAPABLE OF SAFELY SUPPORTING THE TRAFFIC THAT IS CROSSING THEM. THE CURRENT METHOD OF SURVEYING BRIDGES, TO DETERMINE THEIR STRESS CONDITION, IS COSTLY AND TIME-CONSUMING. THIS PROGRAM WILL DEVELOP ...

DUE TO THE DOWNSIZING OF AUTOMOBILES ON U.S. HIGHWAYS, MINI-CARS HAVE BECOME A MAJOR PART OF THE AUTO POPULATION. THE LIGHT WEIGHT AND HIGH CRUSH RATE OF THESE VEHICLES CAN CAUSEHIGH VELOCITY CHANGE LEVELS WHEN IMPACTING MOST EXISTING BREAKAWAY LUMINAIRE SUPPORTS. THIS INCREASES THE PROBABILI-TY OF INJURY TO OCCUPANTSOF MINI-CARS WHEN IMPACTING LUMI- NAIRE SUPPORTS. CONCEPTS HAVE BEEN DEVELOPED WH ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

THE RESEARCH WILL IDENTIFY AND ANALYZE BOTH THE QUANTITATIVEAND QUALITATIVE ASPECTS OF SECURITY CHECKPOINT OPERATIONS. USING INDUSTRIAL ENGINEERING TECHNIQUES, SCREENING OPERATIONS WILL BE BROKEN INTO BASIC ELEMENTS WHICH WILL THEN BE MEASURED AND INVESTIGATED TO DETERMINE THE INTERRELATIONSHIPS BETWEEN SUCH COMPONENTS AS: - PROCESSING RATES - DISTRIBUTION OF PASSENGER ARRIVALS - BOARDING VOLUMES ...

LIGHT EMITTING PAINTS COULD HAVE MANY IMPORTANT APPLICATIONS, ONE OF WHICH IS IMPROVED SAFETY IN TRANSPORTATION. THE PAINT IS BASED ON SPECIALLY PREPARED GRANUALS THAT ARE PHOTOLUMINESCENT, ACTIVATED BY INFRATED RADIATION AVAILABLE FROM HEADLIGHTS. IT APPEARS THAT THESE MATERIALS WILL CHARGEUP FROMT THE SUNLIGHT OR NATURAL DAYLIGHT AND WILL STORE VISIBLE LIGHT ENERGY FOR ONE YEAR OR MORE. THE CRIT ...

THIS PHASE I PROJECT WILL RESEARCH THE PROBLEMS, CURRENT OPERATIONS, FILE STRUCTURES, AND DATA COMPRESSION REQUIREMENTS TO FACILITATE THE RAPID ERROR-FREE TRANSMISSIONOF WEATHER MAPS, ALPHANUMERIC WEATHER DATASETS, AND SATELLITE IMAGES. SUPPORTING THE INTERAGENCY FIRE WEATHER PROGRAM, IT WILL ALSO RESEARCH THE COMMERCIALLY AVAILABLE HARDWARE AND SOFTWARE WHICH WILL MEET TRANSPORTABILITY, RELIABILI ...
