The Wrong-Way Detection System uses video cameras to detect vehicles that are traveling in the wrong direction. If a vehicle is detected, wrong-way signs outlined with multiple sets of red lights are activated and begin flashing to alert the driver they are traveling in the wrong direction. Additionally, the system alerts the CTDOT Highway Operations Center and local State Police Troop barracks in real-time, allowing staff to monitor the activities of the wrong-way driver on the ramp.

The work is being performed by Tapco.
