It's hard to imagine a more egregiously clear-cut case where a driver deserves a harsh prison term than when drunk driver Kieran Brewer ran over and killed a minor inside a crosswalk. Surely, unlike other cases where sober drivers killed pedestrians and faced few consequences, these circumstances would spur the judicial system into action.

A new online map begins to show which San Francisco streets have the worst speeding problems, according to data from SFMTA engineering and traffic surveys. The map was created by Stephanie May, who works for the SF-based organization Urban Mapping and teaches cartography at SF State University and history at Stanford, according to her Twitter page.

Every day at 6 p.m., San Francisco's parking meters shut down. But in many neighborhoods, motorists continue to seek parking, and without the turnover brought by meters, the streets become clogged with drivers circling around for a spot.

The SFMTA and the Planning Department presented detailed plans for Polk Street at the project's final open house meeting yesterday. The new aspects include specific locations of bulb-outs, dedicated bicycle signals, left turn prohibitions, loading zones, and new trees and landscaping. Plans to improve bicycle infrastructure are still composed of a mix of protected, buffered, conventional, and part-time bike lanes, depending on the stretch and side of the street.

The SFMTA extended the buffered bike lanes on Bayshore Boulevard earlier this month from Silver Avenue south to Paul Avenue, reducing four traffic lanes to two. The street now provides a calmer, safer bicycling link for Bayview residents all the way up to where Bayshore ends, at Cesar Chavez Street and the "Hairball" freeway interchange.

The expansion of Bay Area Bike Share into the Mission, the Castro, Hayes Valley, and Mission Bay planned for early this year won't happen until fall at the soonest, due to the recent bankruptcy of Bixi, the company that supplies hardware and software for several American bike-share systems.

The SF County Transportation Authority issued a new report Monday to guide the expansion of Bay Area Bike Share, which sees 90 percent of its rides in San Francisco, despite the city encompassing half of the system's bikes and stations.

The SF Police Department is issuing more traffic tickets, and a greater share of them are going toward the five most dangerous violations, according to early SFPD data on traffic citations issued so far this year.

Sidewalk widenings on Irving Street in the Inner Sunset, proposed by the SFMTA to make it safer and easier for tens of thousands of commuters to board the N-Judah, have been cut down in size to a fraction of the original proposals due to neighborhood complaints about losing car parking and protests from the SF Fire Department.
