1. A method of monitoring traffic speed and for gathering evidence, said method comprising the steps of:

  • providing a monitoring vehicle equipped with a traffic speed monitoring and evidence gathering device, said device having traffic speed detecting means for determining the absolute speed of a moving vehicle proximal to said monitoring vehicle, and for generating detection output including speed information establishing the absolute speed of said moving vehicle when said absolute speed exceeds a predetermined magnitude;

    a video camera operably coupled with said detecting means for receiving said speed information, and for creating an identifying moving video image of said moving vehicle in response to said speed information,said video camera including zoom lens means for taking the zoom image of the license plate of said moving vehicle, and for taking the full image of the entirety of the moving vehicle,said video camera also including microphone means for recording the audible observations of said operator relative to said moving vehicle; and

    a global positioning system monitor operably coupled with said speed detecting means and said speed detecting means and said camera for creating position-identifying information about said monitoring vehicle, and for delivering said position-identifying information to said camera only in response to said detection output,said camera including means for imposing said speed information, said audible observations and said position-identifying information on said zoom and full images;

    placing an observer within said monitoring vehicle, and causing the monitoring vehicle to travel on a roadway where a moving vehicle is found;

    operating said traffic speed detecting means to determine the absolute speed of said moving vehicle;

    when said absolute speed exceeds said predetermined magnitude, operating said video camera and said zoom lens means to take a zoom image of the license plate of said moving vehicle and the full image of the moving vehicle;

    causing said operator to audibly speak observations into said microphone means about said moving vehicle; and

    imposing on the image created by said video camera said speed information, said audible observations and said position-identifying information.
