Celebrating a win! In April 2020, the City of Atlanta approved Safe Speeds & Vision Zero legislation. Read more.
What's next for the goal of setting safe speeds?
- Because the legislation adopted does not cover all streets, we are seeking expansion to cover collector streets (e.g. Atlanta Student Movement Blvd) and minor arterials (e.g., Cascade Road).
- Legislation passed by Atlanta City Council in May 2020 reduced the speed limit on Hosea Williams Dr (a collector) from 35 to 25 mph. This originated with a neighborhood transportation committee request in fall 2019 so neighborhood advocates, let us know if you'd like help reducing the limit on a street in your community!
It’s a constant complaint in every neighborhood meeting: Drivers are going too fast. For some Atlantans, it’s just a nuisance or a fact of life in a city. For people who use our streets outside of vehicles (that’s everyone at some point), even a small increase in driving speed becomes a matter of life or death in a collision.
In 2018, 6,283 pedestrians and 857 cyclists were killed in the U.S. That means a pedestrian or cyclist was killed somewhere in the U.S. every 73 minutes. That number is the highest it has been in 30 years, even though overall traffic fatalities went down slightly last year. This doesn’t include an unknown number of scooter-related fatalities since they rolled out nationwide since 2018.
On top of that, children, older adults, and people of color face a disproportionate risk of injury and death walking on our streets. This is a serious issue in Georgia. Our state moved from #10 to #6 in a national ranking of pedestrian danger based on fatalities from 2008 to 2017.
Atlanta stands out when it comes to deaths in pedestrian crashes by population. In 2017, Atlanta ranked 23rd out of the 175 largest cities in the nation for our pedestrian fatality rate: that’s how many pedestrians were killed as a percentage of total traffic fatalities. What that number tells us is that pedestrians are especially vulnerable in our city.
Slower streets are safer and better for people.
It’s simple: The faster a driver is going in a collision, the more likely a pedestrian will be killed or seriously injured. That seems obvious, but it’s important to understand that a small change in speed can have a significant difference in the outcome. From a driver’s perspective, the difference between 15 mph and 30 mph is a light tap on the gas pedal. For a person walking across the street, a small change in speed can be the difference between a bad day and a life-changing injury or death.
Research by the AAA Foundation for Traffic Safety finds that the risk of severe injury or death of a pedestrian quickly increases with speed.
The risk for children and elderly pedestrians is even greater at lower speeds. The animated graphic below was created by ProPublica from the same AAA data:
On top of that, the popularity of SUVs brings a higher risk of injury and death when compared to conventional cars, in part because it’s more likely that pedestrians will be run over rather than roll up onto the hood. We’ll save the topic of distracted driving for another day (it’s not good).
It’s not only the force at which a driver strikes a pedestrian that is important. Higher speeds reduce the sight distance and reaction time a driver needs to avoid a collision in the first place. The images below show a driver’s field of vision at different speeds. When speed goes up, it’s more difficult for drivers to see and respond to objects and people outside that view.

Reducing speed limits is an effective way to reduce speed.
Cities across the United States and the world are reducing speed limits as one way to reduce traffic fatalities and injuries. Vision Zero is an international movement that Atlanta must join if we are going to truly realize our commitments to equity, mobility, and sustainability. That’s why speed limits and Vision Zero are important parts of Atlanta Bicycle Coalition’s policy platform.
By reducing the speed limit, top outlier speeds are reduced. In Boston, default speed limits on most local streets were set at 25 mph. The Insurance Institute for Highway Safety found the odds of drivers exceeding 35 mph fell by almost 30%. In Seattle, the city has established 25mph speed limits on all its arterial streets and 20 mph on all its local streets. In a pilot study in Springfield, Missouri, reducing the speed limit in some neighborhoods from 30 mph to 25 mph had a proven effect of slightly slowing down all driver speeds, even with no other street changes.
Citywide speed limits are still a relatively new trend in the United States and it will take more time to see data on their benefits. There is a large body of evidence in other countries showing the safety benefits of reduced speed limits. In Bristol, UK, researchers found a 63% reduction in fatal injuries since a city-wide 20 mph (30 kph) speed limit was enacted.
Lower speeds don’t necessarily mean it will take longer to get where you’re going in a city. During the times of day when traffic in Atlanta is the most congested, speeds on many streets average less than 25 mph. What's more, 25 mph allows vehicles to travel a more consistent pace with fewer stops and starts, smoothing traffic flow. In fact, in congested conditions, traffic can flow better at lower speeds. Often in Atlanta, drivers are only driving at high speeds between traffic lights, which is both unsafe and inefficient.
Redesigning streets takes a lot of time and money. We will continue to advocate aggressively for engineering solutions to make our streets safer, including protected lanes, crosswalks, traffic calming, signal phasing, and much more. Lower speed limits won’t solve everything, but lower speed limits will help save lives right now while we continue investing in the future.
It's time to adopt safe speed limits in Atlanta.

Cascade Road, Cascade Avenue, and Ralph David Abernathy Boulevard are three sections of one critical corridor that serves dozens of Southwest Atlanta neighborhoods.
Two of the three sections, Cascade Road and Ralph David Abernathy Boulevard, are part of the High-Injury Network and ranked among the most dangerous roads in the city of Atlanta. The third section -- connecting these two High Injury streets -- is Cascade Avenue.
On January 19, 2019, David Gordon, a 52-year-old beloved longtime resident of Cascade Ave, was struck and killed by a driver while crossing Cascade Ave. He was in a crosswalk. The collision happened less than a quarter-mile mile from where the street name changes to Ralph David Abernathy Boulevard.
A “Complete Street” project was proposed in 2016 to address the hazardous conditions on Cascade Avenue, where David lost his life, but the construction funding was cut due to budget shortfalls. At the same time, thanks to the persistent work of community leaders and local advocates, in March 2019 Cascade Road in District 11 received funding to become a Complete Street. (Complete Streets are roads with safe spaces for people in all modes of transportation, whether they are walking, biking or scooting, and driving.) A section of Ralph David Abernathy Boulevard in Westview was funded as well and completed in 2018.
Following a community-led #RespectCascade action to highlight the urgent need for safety improvements on Cascade Avenue, the City of Atlanta revised the Cascade Complete Street project to include some safety improvements that could be added during the street resurfacing. Elements include bus stop enhancements, bicycle lanes, and pedestrian safety improvements.
We will continue to support communities along Cascade Ave in calling on the City of Atlanta to keep the vision of a safer, more accessible Cascade corridor alive.308 signatures
On the crash heat map below, the intersection of Cascade Avenue and Ralph David Abernathy Boulevard is marked by glowing red and yellow embers, meaning many people walking have been hit by cars at this crossing.
Ralph David Abernathy Boulevard, affectionately known as RDA, serves as a major corridor for schools, historic neighborhoods, and businesses in Southwest Atlanta. RDA is a large street with fast traffic and a lonely stretch of bike lane between Murphy Ave and I-85. The road, whether by bike or by car, is often perilous due to potholes, debris, and jagged train tracks.
RDA turns into Georgia Avenue and runs through seven amazing Atlanta neighborhoods: Westview, West End, Adair Park, Pittsburgh, Mechanicsville, Summerhill, and Grant Park.
The Atlanta Bicycle Coalition connects these neighborhoods at Atlanta Streets Alive. You can help make this a more livable, walkable, and bikeable corridor all year-round by supporting our campaign for bike lanes and regular maintenance on RDA and Georgia Avenue.
In addition to bike lanes on RDA and Georgia Avenue, we are advocating for:
- Resurfacing and repairing dangerous potholes on RDA
- Regularly maintaining this critical corridor by sweeping trash and debris
- Paving over the hazardous out-of-use train tracks
