According to Streetsblog, the traffic lights along Valencia will remain timed for 13 MPH travel for years to come:

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. […]

Following examples in cities like Copenhagen, Amsterdam, and Portland, the signal optimization keeps vehicles traveling at a steady cycle-friendly 13 mph from 16th to 25th streets while garnering benefits for all users.

“The Green Wave signals and the safer, calmer speeds are another step in the right direction for Valencia Street, which is already a thriving commercial corridor thanks to its wide sidewalks and bike lanes and plentiful on-street bike parking,” said Renee Rivera, acting executive director of the San Francisco Bicycle Coalition.

The article goes on to say that the program has not only made biking down Valencia better, but has actually decreased travel times for cars and reduced the amount of air pollution emitted along the street.  Unfortunately, the city does not plan to expand the program (why not?), but is considering doing another “Green Wave” pilot program on the already bike-friendly 14th Street.
