Caltrans has activated onramp meters on the southbound 101/ Ventura Freeway between Rancho Road in T.O. and Las Virgenes Road in Calabasas.

The meters are active weekdays from 5 a.m. to 8 p.m. and Saturdays from 8 a.m. to 8 p.m.

All meters, except two, allow for one vehicle to move per green light. The meters at Kanan Road and Las Virgenes Road to the southbound 101 allow for two vehicles per green light.

Meters on southbound 101 are now active at the following ramps: •In Ventura County: Rancho Road, Hampshire Road and Westlake Boulevard. •In L.A. County: Lindero Canyon, Reyes Adobe, Kanan, Chesebro Canyon, Liberty Canyon and Lost Hills and Las Virgenes roads.

According to Caltrans, metering will reduce bottlenecks and ease the overflow of vehicles when demand exceeds capacity. The meters adapt and readjust to control congestion and help motorists safely through incidents while simultaneously regulating vehicles entering the 101.

Metering also helps alleviate constant streams of vehicle flow that make freeway access difficult for motorists entering the 101.
