Transpo Maps in the News
My latest column: San Francisco’s safe street advocates have long suspected the SFMTA prioritizes revenue over safety in ticketing parked cars. Now there’s data to back it up.
Just 5% of citations go to cars blocking bike lanes, sidewalks and crosswalks.

The real problem with S.F. parking tickets: Most don’t go to dangerous drivers
New data confirms what safe street advocates have long assumed: : The San Francisco Municipal Transportation Agency prioritizes revenue over safety in deciding when to slap drivers with fines.

San Francisco has a car-related death and injury crisis. One of our only tools—enforcement of traffic laws—is ineffective and nearly nonexistent.
If we want to achieve #VisionZero, SFPD needs to be more effective. An op-ed / thread on how they can do it 🧵

The San Francisco Police Department must do a better job of reducing car-related deaths. Here’s how.

🚨 New Research! 🚨
I analyzed every traffic citation the SFPD has written over the past 5 years and crunched the #s.
Not only are they writing just 10 tickets a day, they're also disproportionately targeting BIPOC for non-life-threatening violations. 🧵👇

My latest column: 45 cops work in the San Francisco Police Dept's traffic division. Together, they're issuing just 10 traffic citations a day -- a plunge from 74 citations a day three years ago. "What exactly are they doing?" asked a safe streets advocate.

@sfstandard
230 people have died in traffic accidents in San Francisco since 2014, including 27 last year alone.
Safe streets activist @braitsch mapped those traffic deaths to commemorate the lives lost and to put pressure on the city to do more to prevent them.

San Francisco is saturated w/ cars. 472,409 to be exact. They are everywhere, but where do they actually live?
I pulled data from the DMV and U.S. census and put it on a map. Let's take a look. 👇🧵

Valencia Bike-Lane Violations by Paint and Numbers
Citing vehicles for illegal parking is a necessary, short-term solution but each of these corridors desperately need fully protected bike lanes their entire length as soon as possible.
