FOR IMMEDIATE RELEASE

U.S. Route 101 in San Mateo County Ramp Meters to go Green November 4, 2014
Watch For New Signals at On-Ramps

San Mateo County – The California Department of Transportation (Caltrans) will activate northbound ramp metering on U.S. Route 101 in San Mateo County beginning November 4, 2014.

What is Ramp Metering?
Ramp metering is a traffic management strategy using traffic signals and accompanying equipment and techniques to improve flow on the freeway system. It is intended to improve the safety of vehicle merging.

Motorists at newly activated ramp locations may experience operational delays during the first few days of operation. Caltrans staff will monitor the metered locations and make adjustments, and then fine tune the metering operations.

Northbound Activation
Meters at 18 on-ramps will be activated on northbound U.S. 101 between U.S. Route 92 in San Mateo and the San Mateo/San Francisco County line.
 Beginning Tuesday, November 4, 2014, on-ramp meters will be set to solid green during commute times to alert drivers to the new driving condition.
 On Wednesday, November 12, 2014 on-ramp meters will start cycling through red and green during Northbound PM peak time from 3:00 p.m. to 8:00 p.m.
 On Tuesday, November 18 2014, ramp meters will start cycling during Northbound AM peak time from 6:00 a.m. to 10:00 a.m.

Drivers entering U.S. Route 101 where on-ramp meters are activated should stop at red and wait until the metering light turns green to enter U.S. Route 101. Caltrans will monitor traffic conditions and operate ramp meters as appropriate.

Additional Information: All on-ramps will operate at “1 car per green” except for two
freeway to freeway connector ramps which will meter and operate at “2 cars per green”.

The two freeway connectors are the Westbound State Route 92 to Northbound U.S
Route 101 Connector, and Eastbound I-380 to Northbound U.S. Route 101 Connector.
