• Abstract:
  The objective of this activity was to record video that could be used for controlled
  
  evaluation of video image vehicle detection system (VIVDS) products and software upgrades to
  
  existing products based on a list of conditions that might be difficult to find in a timely manner.
  
  This library allows the user to present a wide range of weather, roadway, and lighting conditions
  
  to a VIVDS product in real time. The idea involves capturing the video and playing the recorded
  
  video through a VIVDS processor to determine the accuracy or change in accuracy to compare
  
  against a test protocol and/or verify claims of manufacturers. The test conditions include
  
  situations that are not easily obtainable and that might be particularly challenging for current
  
  detectors.
  
  This research task anticipates that TxDOT will encounter situations fairly often in which
  
  the desired conditions for full-scale field testing of VIVDS are not available or where quick
  
  turnaround tests are needed. There may be a need for a quick decision on a firmware upgrade or
  
  on a new product to establish at least an initial and preliminary basis for forming a decision on
  
  success or failure. There will probably be occasions where these initial results using the video
  
  library need to be verified by field testing if the desired conditions become available or if time
  
  and other resources allow such testing. TxDOT might want to establish a formal policy for the
  
  use of the library and conditions in which field testing might be desirable.
