Full Ramp Metering Activated Westbound/Southbound on Highway 4 and Highway 242 in Concord

Contra Costa County—Caltrans today announced it has activated full ramp metering operations in the the westbound/southbound direction of Highway 4 and Highway 242 in Concord.  This ambitious project is part of the Metropolitan Transportation Commission’s Freeway Performance Initiative, aimed at maximizing the capacity of existing roadway by targeting congestion during commute hours.  “ Metering lights improve safety by controlling the flow of merging vehicles,” said Caltrans District 4 Director Bijan Sartipi. “When merging-related accidents are reduced, travel time improves for everyone.”

The ramp meters installed as part of this project are state-of-the-art meters that can adapt to current traffic conditions.  These meters will automatically adjust the green rate on the meters based on traffic flows both at on-ramps and on the highways themselves.  This innovative ramp metering system is a collaborative effort among Caltrans, the Contra Costa Transportation Authority and the Metropolitan Transportation Commission to facilitate faster and more reliable travel time along this busy corridor.

“ Ramp meters are a key part of MTC’s Freeway Performance Initiative, which is designed to deliver maximum performance from our existing freeway network, “ explained MTC Chair and Orinda Mayor Amy Rein Worth. “We’ve already seen the dramatic improvements in drivers’ travel times made by the activation of ramp meters along U.S. 101 in San Mateo County and Interstate 580 in Alameda County. It is great to see these low-cost, high-yield improvements coming for our commuters in Contra Costa County, too. “

Caltrans deployed “Metering Begins” signs along Highway 4 from Solano Way to Railroad Avenue and on Highway 242 from Clayton Road to Port Chicago Highway. All 23 meters on these stretches of highway were set to “green” on September 9, 2013 during the morning  (6:00 am to 10:00 am) in the westbound/southbound direction and evening (3:00 pm to 7:00 pm) in northbound/eastbound direction to give drivers a chance to get used to the new system.

Full ramp metering begins on September 17, 2013 in the westbound/southbound direction of Highway 4 and Highway 242.  Metering lights in the eastbound/northbound direction will go live on September 24, 2013.

As has been common throughout the state, newly activated ramp locations will experience some delays during the first few days of operation as drivers adjust to the meters.  Caltrans staff will monitor the metered on-ramps and make adjustments to fine-tune the metering operations.

Drivers who want to obtain more information can call the Ramp Metering Information Line number at 510-286-4531.
