DEER DETECTOR AND COUNTER SYSTEM CONTRACT. FINAL TECHNICAL REPORT

AN EVALUATION AND TEST ARE MADE OF METHODS FOR THE DETECTION AND COUNTING OF DEER SO THAT DEER-VEHICLE ACCIDENTS MIGHT BE REDUCED. EVALUATION OF MECHANICAL, MAGNETIC, SONIC, VISUAL LIGHT AND PASSIVE AND ACTIVE INFRARED, BARRIER OR STRIP DETECTION TECHNIQUES WERE MADE. THE RESULT FOR DETECTOR TECHNIQUES WAS GENERALLY NEGATIVE. ONLY THE ELECTRO-OPTICAL TECHNIQUE SHOWED ANY PROMISE. HOWEVER, THIS TECHNIQUE IS LIMITED TO CLEAR NIGHTS AND DAYS OF MODERATE TO LIGHT SURFACE HEATINGS. SUCH THINGS AS BLOWING SNOW, RAIN OR DUST WILL ALSO CREATE FALSE DETECTIONS. THE EQUIPMENT CAN BE OPERATED WHEN THE VISIBILITY IS REDUCED TO 50% AS LONG AS THE RATE OF CHANGE OF VISIBILITY IS SLOW. NORMAL DAILY WEATHER CHANGES DO NOT CAUSE ANY PROBLEM, BUT THE ABOVE MENTIONED WIND GUSTS CAN. THESE TECHNIQUES ARE NOT RECOMMENDED FOR GENERAL ALL WEATHER USE. THE ELECTRO-OPTICAL TECHNIQUE CAN BE USED ON A LIMITED BASIS. THE PROBLEM OF COUNTING DETECTIONS WAS SUCCESSFULLY SOLVED BY USING EXISTING STREETER AMET PORTABLE COUNTERS. THIS COUNTER HAS PROVEN RELIABLE AND IS REASONABLY PRICED. THE FEASIBILITY OF AN ELECTRONIC SCARECROW APPEARS TO BE NEGATIVE SINCE THE ANIMALS ARE NOT DISTURBED BY LIGHT OR SOUND SOURCES. /AUTHOR/
