A roadway identified by The City as one of its most dangerous – Lombard Street– may soon net a major safety makeover.

If the $12 million safety overhaul is approved by the San Francisco Municipal Transportation Agency’s Board of Directors on Tuesday, Lombard Street could be redesigned to feature numerous curb extensions called “bulbouts,” which help pedestrians become more visible behind parked cars, and also reduces the distance from curb to curb when crossing the street.

SFMTA would also paint “zebra” style high-visibility crosswalks all across Lombard, which the agency says reduces crashes with pedestrians by 37 percent. Leading Pedestrian Intervals, which let walkers cross briefly before cars allowed to move, would also be installed.

Advanced limit lines would also be painted at intersections. These are lines restricting cars to stopping ten feet before crosswalks. ...

These changes won’t take place on Lombard’s famous crooked portion – rather, they will happen between Francisco and Franklin streets, leading to the entrance of Golden Gate Bridge near the Presidio.

This portion of Lombard is more akin to a freeway, as it’s technically a leg of U.S. Highway 101, under the purview of Caltrans. Caltrans plans to repave Lombard in 2018, giving SFMTA a chance to revamp the street for safety.

City officials identified Lombard as one of its most dangerous streets in a study for its Vision Zero policy, in which The City pledged to end all traffic deaths by 2024. On Lombard between 2008 and 2013, there were over 150 collisions resulting in injuries, two of which were fatal and 20 severe, according to the SFMTA.

101 along Lombard isn't at all akin to a freeway.  Okay, they are both paved and have more than two lanes, but that's it.  Lombard is a city street.

What would help most along this section of Lombard would be to synchronize the traffic signals.  I read somewhere that the city of San Francisco was having issues with the inductive loops failing.  Instead of replacing the loops they were just putting the traffic signals into timer only mode.  New loops will have to be installed when the roadway is repaved, so perhaps this will help things.

Also, this stretch of Lombard is one of the few divided streets in San Francisco that allows left turns on weekends and at non-peak weekday hours.  Most other divided streets always ban left turns or allow them only where left turn lanes are present.  The traffic volume on Lombard has reached a level where this causes safety and operational issues.

There is also a project just south of here on US 101 to add Bus Rapid Transit lanes to Van Ness Avenue.  The roadway is currently 3 lanes each way and will be narrowed to 2 lanes each way with a center median for the BRT lanes.  Construction for this project was supposed to start in December 2015, but has been pushed back to "Early 2016."  As of today (March 30, 2016) there has been no visible work.
