Intersection Video Detection ManualAuthor/Presenter: Bonneson, James; Abbas, Montasir
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 manual assists engineers with the planning, design, and operation of a VIVDS. This assistance is provided in three ways. First, the manual provides information about critical issues associated with the planning, design, and operation stages. Second, it provides information to guide engineers in making appropriate decisions during each stage. Third, its comprehensive coverage should enable engineers to thoughtfully direct others during VIVDS installation and maintenance activities.
