Video imaging vehicle detection systems (VIVDSs) are becoming an increasingly common means of detecting traffic at intersections and interchanges in Texas. This interest stems from the recognition that
video detection is often cheaper to install and maintain than inductive loop detectors at multi-lane intersections. It is also recognized that video detection is more readily adaptable to changing conditions at the intersection (e.g., lane reassignment, temporary lane closure for work zone activities). The benefits of VIVDSs have become more substantial as the technology matures, its initial cost drops, and experience with
it grows. This research was conducted to gather information about VIVDS planning, design, and operations and to develop guidelines that describe the "best" practices for Texas conditions. This report documents the findings from the information gathering and guideline development activities. The guidelines are intended to inform engineers about critical issues associated with each stage, to guide them in making appropriate
decisions during each stage, and to enable them to thoughtfully direct others during VIVDS installation and maintenance activities.
