Ramp signals are traffic signals at freeway on-ramps that control the rate of vehicles entering the freeway. The signals can be set for different metering rates to optimize freeway flow and minimize congestion. When in operation, ramp signals will alternate between the red and green lights, restricting the number of vehicles entering the freeway, thereby reducing congestion, bottlenecks and managing the traffic flow on the mainline.
