Researchers for Michigan DOT developed a system to evaluate bridge decks at near-highway speeds. The vehicle-mounted 3D optical bridge evaluation system (3DOBS) uses GPS, a high-tech camera, and an inertial measurement unit to collect bridge deck imagery for inspectors’ use. The system will help bridge inspectors safely quantify deck distresses and optimize the timing of preservation treatments.
