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!
