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.

Muni Adding More Service July 9

Muni Adding More Service July 9 By Mariana Maguire The 6 Haight/Parnassus was temporarily suspended in March 2020 and will be brought back into service July 9, 2022, along with the 2 Sutter and 21 Hayes.  As the SFMTA prioritizes service equity and responds to changing travel patterns, we are planning to bring back additional routes that have been temporarily suspended since March 2020: The 2 Sutter (formerly 2 Clement), 6 Haight/Parnassus and 21 Hayes. The 6 Haight/Parnassus will return to its full pre-pandemic route, while the 2 Sutter and 21 Hayes will return in response to community feedback with changes to make the most of limited resources. System improvements like transit-only lanes and subway upgrades have helped us make transit service more reliable overall as we keep restoring routes.   These changes are part of the 2022 Muni Service Network plan .

New top story from Time: China Calls U.S. Policy ‘Misguided’ in High-Level Talks

https://ift.tt/3iPgwS0 TIANJIN, China — China came out swinging at high-level face-to-face talks with the United States on Monday, blaming the U.S. for a “stalemate” in bilateral relations and calling on America to change “its highly misguided mindset and dangerous policy.” Vice Foreign Minister Xie Feng accused the administration of President Joe Biden of trying to contain and suppress China’s development, according to an official summary of his remarks in talks with visiting U.S. Deputy Secretary of State Wendy Sherman. The fundamental reason why relations between the two face serious difficulties is because some Americans portray China as an “imagined enemy,” the Foreign Ministry quoted Xie as saying. [time-brightcove not-tgx=”true”] Sherman, America’s No. 2 diplomat, is the highest-ranking U.S. official to visit China since Biden took office six months ago. She was having separate meetings with Xie, who is in charge of U.S.-China relations, and Foreign Minister Wang Y...

New top story from Time: DOJ Reportedly Investigating Whether New York Gov. Cuomo Manipulated Data on COVID-19 Nursing Home Deaths

https://ift.tt/3u8AJab (ALBANY, N.Y.) — New York Gov. Andrew Cuomo faced mounting challenges to his leadership on the coronavirus pandemic Wednesday as state lawmakers threatened to strip him of the power to issue emergency orders and federal investigators scrutinized his administration’s handling of nursing home data. The U.S. Justice Department has been examining the governor’s coronavirus task force and trying to determine whether the state intentionally manipulated data regarding deaths in nursing homes, two people familiar with the matter told The Associated Press. The people, who weren’t authorized to discuss the investigation and spoke on condition of anonymity, said the Cuomo administration had not been cooperative with prosecutors, especially in the early stages of the probe, and for months had not produced documents and other data the Justice Department had requested. The inquiry began months ago in the Justice Department’s civil division, and parts of it have ...

Van Ness Improvement Project Nears Completion

Van Ness Improvement Project Nears Completion By Nehama Rogozen After years of planning and construction, work on the Van Ness Improvement Project is progressing rapidly and the end is in sight! Construction is projected to be finished by the end of this year, with Bus Rapid Transit (BRT) service running on Van Ness Avenue from Mission to Lombard beginning in early 2022. Work on the red transit lanes between Broadway and Pacific is almost complete. Crews have been busy on Van Ness Avenue. You may have noticed them building new medians and sidewalks, paving the roadway and installing poles that provide lighting and power to the BRT system. Most recently they have installed the red lanes that will allow buses to move Muni and Golden Gate Transit riders quickly along the corridor, without getting stuck in traffic. To ensure durability and reduce fading, these red transit lanes are made from poured red concrete, as opposed to red paint or thermoplastic on top of concrete. We are als...

New top story from Time: Larry Nassar Is in Prison, But Many Young Athletes Are Still at Risk. Here’s How We Can Better Protect Them From Sexual Abuse

https://ift.tt/3kU3o0y Earlier this month, the Department of Justice released a report about the FBI’s investigation into former USA Gymnastics doctor Larry Nassar that spotlighted what survivors like me have known to be true: the entire system is failing athletes. The FBI failed to conduct a thorough and timely investigation, and at least 70 victims were sexually abused after allegations had already been reported. The report was as outrageous as it was heartbreaking. The DOJ report found that the FBI failed to respond to the accusations against Nassar in an ethical and efficient way, proving that the FBI—a government institution that should protect its citizens—failed at protecting child athletes. It is unacceptable that multiple institutions, including the FBI, have failed to this extent and not prioritized the well-being of young athletes.

New top story from Time: Simone Biles Pulls Out of the Olympic Gymnastics Team Event Final

https://ift.tt/3kWdnT4 After one rotation, defending Olympic all-around champion Simone Biles pulled out of the women’s gymnastics team event final. With Team USA competing on vault in the first rotation, Biles took to the podium and launched herself into the air. Once airborne, however, she seemed to lose her bearings and looked off to the side on the way down. Instead of completing two and a half twists, in a vault named after her , she was only able to complete one and a half. That lowered her start value and execution score, and she immediately spoke to a trainer after coming off the podium. [time-brightcove not-tgx=”true”] After consulting with the trainer for a few minutes, the two left the arena, but rushed back minutes later before the next rotation on uneven bars while her coach, Cecile Landi, consulted with officials. Biles removed her hand and wrist grips, a sign that she would not be performing on uneven bars. After hugging her teammates, she put on her warm u...
