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.

    Traffic engineers can use the latest advances in vision technology to streamline and enhance traffic management. The idea of using one camera to perform all functions at an intersection is attractive to authorities for many reasons and camera supplier Gridsmart says it can make this happen. Its Bell Camera offers a horizon to horizon view that includes the centre of the intersection where vehicles, bicycles and pedestrians cross paths and it can be used for traffic light actuation, traffic data collection a

The technology which uses our roads will also provide information on road conditions but V2X isn’t the only

    Pilot study on in-car advice of green and blue waves
    In the Netherlands, researchers are carrying out a pilot study using the Radio Dynamic Speed Advice (RDSA) app, developed by Dutch company Amaryllo MMG, specialist in radio technology, aided by navigation solution solutions provider NNG, who integrated the app into their software. The study aims to determine how intelligent apps can positively influence human behaviour in traffic. Around 300 participants driving on a busy access road are currently being provided with in-car advice on how to catch green wave
