Five Years of Data Show: Our Street Safety Projects are Making a Difference

Five Years of Data Show: Our Street Safety Projects are Making a Difference
By Julia Malmo

Ever wonder about the effectiveness of projects after they go into the ground? Us, too!  

That’s why, in 2017, we launched the Safe Streets Evaluation Program to help project teams understand whether a transportation safety project’s design is effective, and where there might be opportunities to adjust the design if not. Project evaluation data can also be combined across projects to help the SFMTA track the effectiveness of a certain type of safety improvement, which can in turn streamline the design of future projects. The Safe Streets Evaluation Program helps us work towards achieving Vision Zero, an initiative to prioritize street safety and eliminate traffic deaths in San Francisco.  

This week, we’re looking back on five years of data gathered through our Safe Streets Evaluation Program with the “2022 Safe Streets Evaluation Summary,” an interactive website summarizing the results of 18 bicycle, pedestrian and traffic safety projects implemented since 2017. 

Each of the 18 projects evaluated in the summary report added significant safety upgrades to the streets. Some introduced vehicle travel lane removals (road diets), separated bikeways, separated bike signals, or left-turn traffic calming devices. Others brought general improvements for pedestrians at intersections including pedestrian signal improvements, daylighting (red zones at intersections) and upgraded crosswalks. For every project, the SFMTA drew on a wide range of data—from project-specific observations, to police reports, to speed data—to create a comprehensive view into its’ effectiveness. 

An infographic displaying the project names, key design element, and results. In the lefthand column, under “Inventory” the following projects are listed: 7th Street, 8th Street, Folsom Streetscape, Golden Gate Avenue, Leavenworth Street, Turk Street, Central Embarcadero, Valencia Street, 6th Street, Safer Taylor Street, Indiana Street, California Street, Page Street, Fell Street, Polk Street, Second Street, Masonic Avenue, Left-Turn Safety. In the center column, under “toolbox,” the following elements are listed: Road lane reductions, separated bikeways, bike signals, pedestrian upgrades, left-turn traffic safety. In the righthand column, under “results”, the following findings are listed: Collisions decreased by 18%; 85th percentile speeds decreased by 3%; bicycle volumes increased up to 75%; vehicle-bike interactions at signals decreased by 93%; vehicles blocking the bike lane decreased by 90%; pedestrian-vehicle close calls decreased by 38%; vehicle travel time increased an average of 50 seconds for 7.3 miles of road lane reductions; left turn vehicle speeds decreased by 17%

The evaluation report indicates that the SFMTA’s safety tools are working together to create safer environments for all modes of transportation on city streets. 

You can dig into the whole set of outcomes on the website, but here are some highlights:  

  • Within the projects evaluated, annual collision rates decreased by 18%  

  • Bicycle-related collision rates decreased by 33% and pedestrian-related collision rates decreased by 32%   

  • Bicycle volumes on streets that received bicycle improvements increased up to 75% in the morning peak (8 AM to 10 AM) commute times, with similar growth in the afternoon/evening peak (4 PM to 6 PM) commute times.   

  • Thanks to protected bikeways, the rate of incidents of vehicles blocking the bike lane decreased by 90%.   

  • Close calls or near misses between pedestrians and drivers decreased across evaluated projects by 38%.  

  • Several projects in under-served communities such as the Bayview and Tenderloin are helping to address historic inequities and under-investment in these neighborhoods.   A table titled “Aggregate Project Findings Across Evaluated Projects”. At the top of the table, a blue bar lists out the column titles: Measure; Metric; Overall Findings; Capital Findings; Quick-Build Findings. In the Collisions section, the following sub-categories are evaluated. For Annual Collision Rate: Overall findings show an 18% reduction; Capital Findings show a 19% reduction; Quick-Build Findings show a 17% reduction. For Annual Bike-related collision rate: Overall findings show a 33% reduction; Capital findings show a 5% reduction; Quick-Build findings show a 42% reduction. For Annual Pedestrian Related Collision Rates: Overall findings show a 32% reduction; Capital findings show a 50% reduction; Quick-Build findings show a 26% reduction. In the Vehicle Speed section, the following sub-categories are evaluated. For 85th Percentile Speed: Overall findings show a 3% reduction; Capital findings show a 5% reduction, and Quick-Build Findings show a 3% reduction. For Max Speed Change Observed: Overall findings show a 20% reduction, and no data is present for either Capital Findings or Quick-Build Findings. For Vehicle Travel Time/Vehicle Travel Time in Seconds: Overall findings show 50.00; Capital Findings show 221.00; Quick-Build Findings show 21.50. For the Bike Volume section, the following sub-categories are evaluated. For AM Bike Volumes: Overall Findings show a 75% increase; Capital Findings show a 187% increase; Quick-Build findings show a 41% increase. For PM Bike Volumes: Overall Findings show a 72% increase; Capital Findings show a 107% increase; Quick-Build Findings show a 62% increase. In the Bike Signal Interactions and Close Calls section, the following sub-categories are evaluated. For Bike-Vehicle interactions: Overall findings show a 93% reduction; Capital findings show no data; Quick-Build findings show a 93% reduction. For Close Calls (near misses): Overall findings show a 62% reduction; Capital findings show no data; Quick-Build findings show a 62% reduction. For Average Daily Interactions Post-Implementation: Overall Findings show 2.2; Capital Findings show 0.3; Quick-Build Findings show 3.1. For Bike Compliance w/ Bike Signal: Overall findings show 87% compliance; Capital Findings show 86%; Quick-Build Findings show 88% compliance. For Vehicle Compliance w/ No Turn On Red: Overall findings show 90% compliance; Capital Findings show 86% compliance; Quick-Build findings show 92% compliance. In the Blocking the Bikeway section, Rates of Incidents was evaluated. Overall Findings show a 90% reduction; Capital Findings show a 19% reduction; Quick-Build Findings show a 90% reduction. In the Vehicle-Pedestrian Close Calls Section, Close Calls (near misses) were evaluatd. Overall Findings show a 38% reduction; capital findings show a 0% reduction; quick-build findings show a 34% reduction

The Safe Streets Evaluation team will continue to think creatively about how to build on the evaluation work and use it to inform our current and future projects, programs, and practices through developing a publicly accessible database of all Safe Streets Evaluation data and finding better ways to evaluate project outreach efforts.

New top story from Time: Pioneering Gay Rights Activist and Photojournalist Kay Lahusen Dies at 91

https://ift.tt/34uhD2y Kay Lahusen, a pioneering gay rights activist who chronicled the movement’s earliest days through her photography and writing, has died. She was 91. Known as the first openly gay U.S. photojournalist, Lahusen died Wednesday at Chester County Hospital outside Philadelphia, following a brief illness. Together with her partner, the late activist Barbara Gittings , Lahusen advocated for gay civil rights years before the 1969 Stonewall uprising in New York helped launch the modern LGBTQ era. She captured widely published images of some of the nation’s first protests. Lahusen “was the first photojournalist in our community,” said Mark Segal, a friend of more than 50 years and founder and publisher of the Philadelphia Gay News. “Practically every photo we have of that time is from Kay.” [time-brightcove not-tgx=”true”] Lahusen photographed a series of gay rights demonstrations held in front of Philadelphia’s Independence Hall each July 4 from 1965 to 1969...

Virtual Permit Transition Summary

Virtual Permit Transition Summary By Stephen Chun Effective April 1, 2022 the SFMTA will transition annual Residential Parking Permit (RPP) permits from physical stickers to virtual permits. This will streamline the RPP application and administration process. This change will not apply to other permit types—including 1 Day, Visitor, Press, City Vehicle, Teacher and Contractor permits.   Currently, about 70,000 San Francisco residents living in RPP areas purchase an annual parking permit in sticker form each year. Those renewing their permit at the same address can pay online and receive their permit in the mail.  People buying new permits can do so (a) in-person at the Customer Service Center, where the customer receives their physical sticker at time of purchase, (b) by-mail, or (c) online, and receive their permit in the mail.   Virtual permits have several benefits, such as:  Permit is active as soon as it is paid. No waiting for a permit to be ma...

New top story from Time: Germany Has Officially Recognized Colonial-Era Atrocities in Namibia. But For Some, Reconciliation Is a Long Way Off

https://ift.tt/3fVRkaO The German government formally recognized colonial-era atrocities against the Herero and Nama people in modern-day Namibia for the first time, referring to the early 20th century massacres as “genocide” on Friday and pledging to pay a “ gesture to recognize the immense suffering inflicted.” “In light of the historical and moral responsibility of Germany, we will ask Namibia and the descendants of the victims for forgiveness,” said German Foreign Minister Heiko Maas in a statement , adding that the German government will fund projects related to “reconstruction and the development” of Namibia amounting to €1.1 billion ($1.3 billion). The sum will be paid out over 30 years and must primarily benefit the descendants of the Herero and Nama, Agence France-Presse reported . [time-brightcove not-tgx=”true”] Although it’s a significant step for a once colonial power to agree such a deal with a former colony, there’s skepticism among some experts and ob...
