For a few weeks now, bicycle riders accustomed to Valencia Street’s “green wave” signal timing have noticed that the system seems out of whack. Many say they’ve been hitting red lights where they’ve normally been able to breeze through the synchronized signals at 13 MPH without stopping.
Well, it’s not your imagination. SFMTA spokesperson Paul Rose confirmed that “there is a sync problem on Valencia.”
