What is Ramp Metering?
Ramp metering is a traffic management strategy using traffic signals accompanying equipment and techniques to manage on-ramp flow used to access the freeway system. It is intended to improve the safety of vehicles merging and the flow of traffic on the highway.

The Purpose
The Purpose of ramp metering during AM and PM commute hours is to maintain optimum travel speeds and to improve travel time reliability along NB US-101 by managing the number of vehicles entering the freeway. By limiting the number of vehicles entering the freeway during periods of congestion, freeway speeds and travel time may improve. Metering rates may be adjusted when traffic demand increases in the future.
