Accomodating Bike Speeds by Re-timing Signals on Valencia Street

As the cyclists in this video point out, re-timing signals for bike speeds (Green Wave) would make roads safer for all street users on Valencia Street. Before
even mentioning re-timing signals, this was many cyclists’ top request
to improve their journey.

Recently, the San Francisco Municipal Transportation Agency (MTA) found that
during peak commute times vehicles run more efficiently when signals
are timed at the speeds they actually travel during congestion — 12 to
15 mph — rather than the current 25 mph. Major bike streets in
Portland, the Netherlands and Denmark have been timed for bike speeds and
now it is time for San Francisco to ride the Green Wave! For more information read my previous SF Streetsblog article on the topic.

  • The first question I asked Chris Daly on inauguration day in 2001 was, that they’d been in office a few hours and why the Market Street signals had not yet been retimed for bicycles?

    What about the issue of signal timing in general. There’s lot of signal stupidity all over town. My (least) favorite example is Sansome at Bush, where the eastbound traffic on Bush enjoys a cycle four times longer than the north/south traffic on Sansome, despite the fact that the Sansome traffic is at least ten times more numerous, if you count the pedestrians, which of course you should do. Another example is the absolute signal preemption enjoyed by the cable car on Powell from Market to California which delays *six* express, one limited, and four local bus lines in favor of a few tens of tourists. Or take the signal at 4th and King which gravely delays the T and the N, each of which can carry a hundred people, in favor of freeway drivers.

    Signal timing all over San Francisco needs to be rethought with a rational approach.

    Please, please, please let this happen. Taking BART from 24th to Downtown is faster than riding, only because of all the red lights.

    I bike and drive up and down Valencia often between 24th and Market. I’ve been paying attention to light timing after reading this post. The narrator in the video states “the signals are timed for cars at 25 miles per hour.” Maybe I’m missing something but that does not seem to be the case at all. Valencia isn’t a green wave in either direction.

    I would love to see a car and/or bike green wave going north-south somewhere around the mission. Maybe Guerrero, Dolores, South Van Ness or another street. But there are no green waves right now.


Bicycle Signal Priority Green Wave Project Stalled

Green Wave in Copenhagen Valencia Street is one of the most heavily biked corridors in San Francisco but its current traffic signals are timed at an auto-only capable speed of 25 mph, leaving bike riders stymied at intersections, or gasping for breath after a mad 15-block sprint. Unfortunately, most riders choose the third option of […]

Green Wave Becomes Permanent on Valencia Street

Valencia Street’s nearly two-year-old Green Wave signal re-timing aimed at prioritizing bicycle traffic speeds continues to please street users, city leaders, and advocates alike. What started as a temporary pilot will become a permanent institution this week with the installation of four new Green Wave signs along the corridor. “Green Waves are the most recent […]

Valencia Signals Re-timed to Improve Traffic Flow and Safety

As Streetsblog San Francisco reported last month, cities around the world have timed their traffic signals to favor slower moving modes, and now San Francisco has started a trial on one of the busiest bicycle routes in the city, Valencia Street. On Thursday February 19th, the MTA re-timed six traffic signals from 16th to 21st, […]

Bikes Now Get Green Waves Along Folsom, North Point, Fulton

The SFMTA has recently re-timed traffic signals to give green waves for bicycle riders on three street segments: North Point from Stockton to Polk Streets, Folsom from 15th to 24th Streets, and Fulton from Laguna to Steiner Streets. With Bike to Work Day set for tomorrow, the SFMTA reviewed its completed projects in a press release today. It […]

SFMTA Installs Second Green Wave for Bikes on 14th Street

The SFMTA recently implemented its second green wave on 14th Street, re-timing traffic signals for more bicycle-friendly speeds from Dolores to Folsom. Following the success of SF’s first green wave on Valencia Street, the 14th Street project was installed in March, said SFMTA spokesperson Paul Rose, adding that the agency is still “evaluating and tweaking it, if […]
