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 did not mention two other street segments announced in September: Arguello from Lake to Clement Streets and Potrero Avenue, from Alameda to 25th Streets. It's unclear if those segments have been implemented yet, but so far six streets are known to have green waves in the city. The first three streets to get bike-friendly signal timing were Valencia, 14th, and 11th Streets.
On all two-way streets that have received green waves, the signal timing works in both directions for bicyclists traveling at a "moderate pace," usually around 11 to 15 MPH, according to the SFMTA.
If you're riding in for Bike to Work Day tomorrow morning, a rally will be held on the steps of City Hall at 8:30 a.m.
