摘要：	The Texas Department of Transportation and other state departments of transportation as well as cities nationwide are using video detection successfully at signalized intersections. However, operational issues with video imaging vehicle detection systems (VIVDS) products occur at some locations. The resulting issues vary but have included: (1) camera contrast loss resulting in max-recall operation, (2) failure to detect vehicles leading to excessive delay and red-light violations, and (3) degraded detection accuracy during nighttime hours. This research resulted in the development of a formalized VIVDS test protocol and a set of performance measures that agencies can incorporate in future purchase orders and use to uniformly evaluate VIVDS products. It also resulted in the development of a VIVDS video library and conceptual plans for a field laboratory for future projects to deploy a range of VIVDS products at an operational signalized intersection. / Title Note: Technical rept. / Supplementary Notes: Sponsored by Texas Dept. of Transportation, Austin.
