542 Global Traffic Technologies (GTT) is to implement its Opticom traffic pre-emption solution at nine of the busiest intersections in the city of Inglewood in California.

Opticom works alongside intersection controllers to help ensure emergency vehicles can move through intersections rapidly and safely, and public transit vehicles can avoid delays and adhere to schedules.

When an emergency vehicle needs to navigate an intersection, the Opticom system on-board the vehicle sends a request to the intersection’s controller ahead of its arrival, which turns the light green when it can do so safely, clearing a path to enable the vehicle’s expedited passage. If a public transit vehicle is running behind schedule, it can send a request for a green signal where possible.

It may seem too good to be true but US company Connected Signals is offering city authorities the equipment to provide infrastructure to vehicle (I2V) communications for free. The system enables drivers to receive information about the timing of signals they are approaching via the EnLighten smartphone app (or connected in-vehicle display).
