What is ramp metering? New traffic signals debut on I-96

Ramp metering will begin on June 18 at eight I-96 entrance ramps in Oakland County to reduce crashes and improve travel times. The system uses traffic signals to control vehicle entry onto the freeway, starting with a yellow flash mode before transitioning to a green/yellow/red pattern during congestion. Drivers must stop at the white line and wait for a green light to merge, with non-compliance treated as a traffic violation.
