Traffic Calming

Crews began work yesterday on an overhaul of Jefferson Street in Fisherman's Wharf that will expand pedestrian space, reduce the number of cars, and create a more welcoming public realm for the throngs of tourists that regularly crowd the street. Improvements on the first two blocks of Jefferson, between Jones and Hyde Streets, were fast-tracked for completion in time for America's Cup, which is set to begin on July 4. Construction was originally scheduled to begin in October, but it was pushed back to January for unspecified reasons.

San Francisco's world-famous commercial strip on Castro Street, which gained a popular pedestrian plaza in 2009, is poised to become a more inviting destination as the SF Planning Department develops plans to widen the sidewalks and install other improvements from 17th Street to 19th Street.

While there's no concrete Pedestrian Action Strategy (formerly the "Action Plan") for San Franciscans to read over yet, city officials went ahead and held a press conference today to tell the public the document is coming next month.

Planners at the SF Municipal Transportation Agency this Saturday unveiled options for redesigning Polk Street as a better place for walking, biking, socializing, and transit. The proposed concepts [PDF] show different ways to arrange the limited amount of street space for traffic lanes (which serve buses on Muni's 19-Polk line), bike lanes, expanded pedestrian areas, and spots for vehicle loading and parking.

John F. Kennedy Drive in Golden Gate Park is a bit calmer since it was reconfigured for San Francisco's first parking-protected bike lane -- and a majority of people like the change, according to a preliminary report [PDF] recently released by the SF Municipal Transportation Agency.

Following a public process that revealed a strong preference for protected bike lanes, the SF Department of Public Works yesterday announced the selection of the preferred option for the Second Street Improvement Project. And yes, the design includes one-way protected bike lanes on each side of the street. The redesign will extend from Market Street to King Street, connecting downtown San Francisco to the SOMA district.

Two blocks of 15th Street, from South Van Ness Avenue to Mission Street, went on a road diet this week. It's part of the SF Municipal Transportation Agency's "Home Zone" pilot project to study the effects of concentrated traffic calming measures on a few blocks around Marshall Elementary School, with the aim of creating a haven of slow-speed streets.

Swamped by demand for safer streets, the SF Municipal Transportation Agency has been working to overhaul the way it delivers speed humps, sidewalk bulb-outs, chicanes, and other measures proven to tame traffic speeds and save lives.

The ongoing streetscape transformation on and around McCoppin Street in recent weeks has brought a new bike lane, raised crosswalks, planted bulb-outs and medians.
