• 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.
