I-64 HRBT Over Height Vehicle Detection System (OHVDS)

Project Description: Hampton Roads District Special Structures Office (HRSS) is enhancing over height vehicle detection in the 1–64 WB Tunnel approach. This system is being developed and implemented to enhancing efficiency in detecting and processing over height vehicles from entering the tunnel. The enhanced system comprises of 3D LIDAR for over height detection, Automated License Plate Reader Cameras (ALPR's) for Vehicle Identification , and Flashing Beacons and Dynamic Message Signs for messaging the drivers of over height vehicles. A standalone workstation at the Tunnel Control Room is used for OHVDs configuration, collation, and managing the system data.
