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.
