Ramp Metering

Ramp metering is a traffic management technique used on highways where sensors and signals control the rate at which vehicles enter from entrance ramps. By regulating this flow, ramp meters help prevent congestion and reduce backups on main roads. Essentially, they act like traffic lights on entrance ramps, allowing a steady, controlled flow of cars onto the highway, which improves overall traffic flow, safety, and reduces travel delays. This system ensures that merging vehicles don’t cause disruptions or slowdowns, maintaining smoother and more efficient traffic conditions on busy highways.
