ACCIDENT SENSING AND SURVEILLANCE SYSTEM

THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE FEASIBILITY OF AN ACCIDENT SENSING AND SURVEILLANCE SYSTEM TO BE USED TO RECORD ON VIDEO TAPE EVENTS LEADING UP TO AND INCLUDING A MOTOR VEHICLE COLLISION AT URBAN INTER- SECTIONS. A LABORATORY MODEL OF THE SYSTEM WAS DESIGNED AND EVALUATED. THE SYSTEM CONSISTS OF TWO VIRTUALLY INDEPENDENT SUBSYSTEMS- A DETECTION-DISCRIMINATION SYSTEM AND A SURVEILLANCE-STORAGE SYSTEM. THE DETECTION- DISCRIMINATION SYSTEM IS DESIGNED TO IDENTIFY THOSE SOUNDS ASSOCIATED WITH MOTOR VEHICLE CRASHES, WHILE DISREGARDING OTHER SOUNDS COMMON TO URBAN INTERSECTION ENVIRONMENTS. THE SURVEILLANCE-STORAGE SYSTEM CONSISTS OF A PAIR OF CONTINUOUSLY OPERATING; NARROW BAND WIDTH TELEVISION SYSTEMS AND TWO MAGNETIC TAPE UNITS. THE TELEVISION SYSTEMS VIDEO SIGNALS ARE CONTINUOUSLY RECORDED ON ONE TAPE UNIT CONTAIN- ING A TAPE LOOP. WHEN A DETECT SIGNAL IS RECIEVED FROM THE DETECTION-DISCRIMINATION SYSTEM, THE INFORMATION IS READ FROM THE TAPE LOOP AND RE-RECORDED ON A PERMANENT STORAGE TAPE FOR LATER ANALYSIS. THE LABORATORY MODEL OF THE SYSTEM OPERATING AT 15 FRAMES PER SECOND DEMONSTRATED A CAPABILITY OF TELEVISING AND RECORDING THE IMAGE OF AN AUTOMOBILE 230 FEET FROM THE CENTER OF AN INTERSECTION WITH A RESOLUTION PERMITTING A MEASUREMENT OF ITS INSTANTANEOUS POSITION TO WITHIN PLUS OR MINUS 5 FEET. /BPR/
