  • 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.
