Bicycling

Distracted driving in SF is no accident. A new map of cell phone use by drivers in SF reveals where drivers are most likely to use a mobile device, increasing the risk of crashes and injuries, and the pattern is unmistakable.

A bill that would allow bicyclists who are ticketed for traffic violations to reduce their fines by attending a traffic safety class was introduced in the California Assembly last week. Assemblymembers Richard Bloom (D-Santa Monica) and David Chiu (D-San Francisco) amended A.B. 902 to repeal a provision in the vehicle code that currently prohibits such diversion programs except in the case of “minors who commit infractions not involving a motor vehicle for which no fee is charged.”

This week the SFMTA extended the southbound bike lane on Polk Street from Post up to Union Street. The stripes are in, and the bike lane symbols are still being stenciled.

Three witnesses told SFPD investigators that Charles Vinson, 66, biked through a red light when he was killed by a driver at 14th and Folsom Streets on March 2, according to police officials.

More San Francisco parents are discovering that cargo bikes are the new family minivan. But while it's increasingly common in SF to spot a parent pedaling their helmeted offspring around, cargo bikes and motorized bikes remain off the radar of most families looking for better ways to get around the city.

What if you could dramatically increase the usefulness of a bike-share system without adding any bicycles or docks? Researchers at the University of Chicago's Booth School of Business have come up with a model that they say could help even the most successful bike-share systems in the world get more bang for the buck.

Several supervisors say they'd like to see city-funded bike education classes distibuted more equally among their districts, and to attract more participants to reduce the per-person cost of the program.

The SFMTA plans to install three more bicycle counters with digital displays on busy biking streets. They will be placed "at visible locations on high volume bicycle corridors," though the exact spots haven't been finalized, according to a city planning document. "Potential locations include Market Street, Valencia Street, and the Embarcadero."

Contrary to initial reports, the SFPD says Charles Vinson, 66, ran a red light on his bike when he was hit and killed by a driver at 14th and Folsom Streets on March 2.
