Aaron Bialick reports that the city's second green wave is now operating on 14th St. after the San Francisco Municipal Transportation Agency began work on the corridor in March. The first green wave has been operating successfully on Valencia St. since January of last year.

SF Bicycle Coalition Communications Director Kristin Smith said the organization "is very pleased to see the ‘green wave' tool used on more and more of San Francisco's key bikeways."

"It's a simple but powerful way to prioritize bike traffic and make bicycling even more convenient and comfortable," she said. "Of course, it's not just good for bike traffic - by pacing traffic to a human speed, green wave streets are safer for everyone."

"(In June), staff from the SF County Transportation Authority plans to propose 'four to six potential new Green Wave corridors along the existing San Francisco Bike Network.' The SFCTA board is expected to approve $71,000 in Prop K sales tax funds in June to plan and implement them, and the document says they could be completed between April and October of next year."

Reporting on the city's first green wave project in January of last year, Aaron Bialick notes that the Valencia St. green wave is not of the same scale as it's more famous cousin.

"The other more widely known Green Wave is Copenhagen's Nørrebrogade, the busiest bicycle street in the Western world, carrying an average of 38,000 cyclists per day with bike lanes as wide as 16 feet. There, implementation of the green wave has also improved the flow of its heavy bus traffic."
