SUTEC S.A. offers illuminated signs of LED technology that indicate to the driver green wave velocity.
Green wave velocity is the speed at which a vehicle should travel on a main road in order to continue passing through intersections without stopping.

With the speeds indicated by the speed givers we enjoy the following benefits:
A better flow and order of traffic
Noise reduction
Less waste of energy and tires: less speeding up and slowing down
Saving tires
Less travel time
Speed giver information is dynamic, and is determined by the centralized traffic systems
