New metering lights at eight southbound on-ramps began shuttling morning commuters onto U.S. Highway 101 in San Mateo County today, all but one working without error, according to California Department of Transportation.
Over the next few weeks, Caltrans officials will be monitoring the progress of the new system designed to alleviate traffic on the busy roadway during morning and evening commute hours, spokeswoman Gidget Navarro said.
Metering signals on the eight southbound on-ramps, including Marsh Road and University Avenue, were turned on today, and Caltrans will turn on lights at the northbound on-ramps next month, according to Navarro.
"It will take time for commuters to adjust to it, but in time, I think they'll appreciate the benefit of metering," Navarro said.
A slight backup occurred this morning near Hillsdale Boulevard due to problems with two metering lights there, but overall, the system worked as planned, Navarro said.
A new addition to the metering system features end-of-queue sensors that detect backups from onramps onto city streets and respond by speeding up the metering signals.
