WebRamp metered is the deployment of a traffic signal(s) on a ramp to control the rate vehicles enter a freeway facility. By controlling the rate vehicles are allowed to enter a autobahn, traffic flow onto the freeway facility becomes more endurance, in essence smoothing the flow off traffic on the mainline real allowing efficient use of existing free capacity.
