542 Global Traffic Technologies (GTT) has provided the city of Norfolk, Virginia, US with an expansion to its Opticom traffic pre-emption solution, which works alongside intersection controllers to help ensure emergency vehicles can move through intersections quickly and safely.

The city has added an additional 15 intersections to its existing emergency vehicle pre-emption (EVP) system, helping to provide faster incidence response times and increased safety.

When an emergency vehicle needs to navigate an intersection, Opticom onboard the emergency vehicle sends a request to the intersection’s controller ahead of its arrival. If the request is granted, the light turns green and the vehicle gets a clear path through the intersection.
