We are working on several maps and data analyses that will be online soon.
In the meantime, explore our collection of projects to help you fight for safer, healthier and more equitable streets.

Portland Gas Tax Analysis
On May 21st, 2024 Portlanders will vote on whether to renew a 10 cents per gallon gas tax to fund the Portland Bureau of Transportation’s “Fixing Our Streets” program. We analyzed 24 projects funded by the gas tax to understand their impact on traffic safety and racial and economic equity.
Car Ownership
and Demographics
These maps show where cars live in a city alongside socioeconomic and demographic data that shows how residents primarily commute, their median income, race, age and whether they own or rent their home. These maps were created to help you advocate for restricting vehicle access in specific areas of your city where residents do not own cars and primarily walk, bike or take public transit to work.
Hayes Valley
Shared Spaces
The Hayes Valley Shared Spaces (HVSS) program has been an economic lifeline for businesses along Hayes Street over the past 3 years and now it is at risk of being reduced from 3 days to 1. This analysis looks at 6 years of vehicle crash data, 911 calls and SFFD emergency response times to Hayes Street to understand the impact the HVSS program has had on public safety.
San Francisco
Parking Enforcement
This analysis provides a detailed audit of 19.5 million SFMTA illegal parking citations since 2008 and shows not only where illegal parking violations are taking place but examines exactly which violations the SFMTA is prioritizing. We also analyzed the effectiveness of SFMTA's current parking enforcement strategy through a both economic and public safety lens and highlight repeat offenders by license plate.
San Francisco
Slow Streets
On December 6th, 2022 the SFMTA Board of Directors voted to preserve or abolish 16 critical Slow Streets across San Francisco. We analyzed crash data from the San Francisco Department of Public Health to understand the impact Slow Streets had on reducing vehicle crashes on each of these residential streets since signs discouraging cut-through traffic were installed.
San Francisco
Traffic Enforcement
In May 2022 we sunshined the SFPD for every moving violation they have written in the past five years and received a spreadsheet of over 64k citations. This map visualizes and analyzes SFPD traffic enforcement activity between January 2018 – May 2022 specifically examining the percentage of citations that "focus on the five" most dangerous violations that result in serious injury and death such as speeding and running red lights. This analysis also investigates SFPD traffic enforcement activity in Equity Priority Communities where residents are disproportionately targeted for non-life-threatening moving violations such as broken taillights and expired tags––citations often used to initiate pretextual stops.
San Francisco
Traffic Fatalities
This map shows where 306 people have been killed by someone recklessly driving a motor vehicle in San Francisco since the city instituted its 'Vision Zero' program in 2014. Wherever possible, we also share information about the victim, the circumstances of the crash and political response (or lack thereof). This map humanizes the tragic loss of life we continue to experience on San Francisco's streets and starts to hold accountable the politicians who refuse to address this public health crisis. A driver crashes their car and hits someone in San Francisco, on average, every four hours. That's six times a day, every single day. Since 2014, San Francisco has lost someone to traffic violence roughly every 13 days. Enough is enough. Please support our work.
Safe Lanes
Illegal Parking App
Safe Lanes makes it super easy to report illegal parking, track repeat offenders and work with your elected officials to demand safer streets.
