A surveillance and control system as designed for the Hampton Roads Bridge-Tunnel Crossing connecting Hampton and Norfolk, VA. The facility consists of two bridges at each end connected by two two-lane tunnels. A control room situated in one of the four tunnel ventilation buildings is the nucleus of the traffic management activities. The system enables vehicle flow control of tunnel access; incident detection, incident verification, and incident operations management; automatic response to environmental and overheight problems; hardware monitoring of the signs, signals, and vehicle detectors; execution of major traffic operations on the faculty upon operator request; and daily reporting and logging of system events. Vehicle data are collected and accumulated by the system and are used for reporting and for performing incident detection and access control.
