If you’ve been driving through U.S. cities and towns, you’ve likely noticed an increase in roundabouts replacing traditional four-way intersections. Some drivers embrace them as an efficient traffic solution, while others find them confusing or even intimidating.
But what exactly is a roundabout, and why is it becoming a preferred alternative to stop signs and traffic signals? Roundabouts are not just about traffic flow—they are a safer, more efficient, and environmentally friendly way to design roads.
Let’s break down what roundabouts are, how they work, and why they are considered one of the most effective traffic management solutions today.
What is a Roundabout? Understanding the Basics

A roundabout—also known as a rotary or traffic circle—is a circular intersection where vehicles move counterclockwise around a central island. Unlike traditional intersections controlled by stop signs or traffic lights, roundabouts operate using a yield-at-entry system, meaning:
✔ Drivers entering the roundabout must yield to vehicles already circulating.
✔ Traffic flows continuously, reducing congestion and unnecessary stops.
✔ Speeds are naturally reduced, leading to safer driving conditions.
Most roundabouts also include:
🔹 Splitter islands – Raised medians that help slow down traffic before entering.
🔹 Pedestrian crosswalks – Positioned away from the central island to increase safety.
🔹 Lane markings – Clear indicators help guide drivers into the correct exit lane.
The result? A smoother, safer, and more efficient intersection that reduces both traffic delays and accidents.
A Brief History of Roundabouts
Many people assume roundabouts are a modern innovation, but their history dates back hundreds of years.
Video : Roundabout Safety Benefits
- 1700s – Early versions of circular intersections appeared in Europe, particularly in England and France.
- 1800s-1900s – Washington, D.C. was designed with multiple traffic circles, inspired by European models.
- 1950s – The United Kingdom introduced the yield-at-entry rule, transforming roundabouts into the efficient system we use today.
- 1990s – The first modern roundabout in the U.S. was built in Summerlin, Nevada in 1990.
- Today – Over 10,000 roundabouts exist in the United States, with more being installed every year.
While roundabouts have been common in Europe and Australia for decades, the U.S. is now rapidly adopting them due to their proven safety and efficiency benefits.
Why Roundabouts Are Safer Than Traditional Intersections
One of the biggest reasons cities are replacing traditional intersections with roundabouts is safety.
1. Fewer Conflict Points = Fewer Accidents
A typical four-way intersection has 32 conflict points—areas where vehicle paths cross, increasing the risk of collisions. In contrast, a roundabout reduces conflict points to just 8.
This means:
✔ No head-on collisions
✔ No dangerous T-bone crashes
✔ Fewer high-speed impacts
According to the Federal Highway Administration (FHWA), roundabouts can reduce serious and fatal crashes by up to 90% when replacing a stop-controlled intersection. Even when replacing a traffic signal intersection, they reduce serious crashes by nearly 80%.
2. Lower Speeds = Less Severe Collisions
In a roundabout, vehicles enter and exit at lower speeds (15-25 mph), compared to the higher speeds (40-50 mph) seen at traditional intersections.
Lower speeds lead to:
✔ Less severe crashes
✔ Fewer pedestrian injuries
✔ Easier decision-making for drivers
3. Safer for Pedestrians and Cyclists

Roundabouts offer better protection for pedestrians because:
✔ Crosswalks are set back from the circular flow, allowing drivers to see pedestrians clearly.
✔ Pedestrians only cross one direction of traffic at a time, making crossings safer.
✔ Cyclists can either merge into traffic or use a designated bike path, depending on the design.
With these safety features, roundabouts significantly reduce pedestrian-related accidents compared to traditional intersections.
Efficiency: Why Roundabouts Improve Traffic Flow
Beyond safety, roundabouts are also more efficient than stop signs or traffic lights.
1. Less Waiting, More Moving
At a traditional intersection, cars must stop at red lights, even when there’s no cross traffic. In a roundabout:
✔ Traffic keeps moving – No unnecessary stops.
✔ Fewer backups – No long wait times during rush hour.
✔ Reduced driver frustration – No more waiting for a green light when there’s no oncoming traffic.
2. Eliminating Left Turns = Smoother Flow
One of the most dangerous and disruptive movements at an intersection is the left turn. Roundabouts eliminate left turns, forcing all vehicles to move in the same direction, improving:
✔ Traffic efficiency – No waiting for gaps in oncoming traffic.
✔ Driver decision-making – No confusion about when to turn.
3. Roundabouts Handle High Traffic Volumes Better
Unlike stop signs and traffic lights, which cause congestion during peak hours, roundabouts allow continuous movement, making them ideal for high-traffic areas.
Environmental Benefits: How Roundabouts Help the Planet

Roundabouts aren’t just safer and more efficient—they also have environmental advantages.
1. Reduced Fuel Consumption
✔ Less idling at red lights = less wasted fuel
✔ Lower speeds = better fuel efficiency
According to studies, roundabouts can reduce fuel consumption by up to 30%, making them a cost-effective solution for drivers.
2. Lower Carbon Emissions
Fewer stops and starts mean lower emissions, helping reduce air pollution in urban areas. Cities that replace signalized intersections with roundabouts see:
✔ Less smog and pollution
✔ Improved air quality
3. Less Road Maintenance Required
✔ No traffic signals = lower maintenance costs
✔ Roundabouts last longer than traffic lights
With less infrastructure to maintain, roundabouts save cities money in the long run.
Challenges: Why Some Drivers Struggle with Roundabouts
Despite their many benefits, some drivers remain hesitant about roundabouts. Common challenges include:
🚦 Confusion about yielding – Some drivers don’t understand that they must yield to circulating traffic before entering.
🚦 Merging issues – Drivers unfamiliar with roundabouts sometimes hesitate, causing unnecessary slowdowns.
🚦 Exit mistakes – Some drivers find it difficult to choose the correct exit and miss their turn.
However, studies show that once drivers become familiar with roundabouts, their confidence improves significantly.

Final Thoughts: Are Roundabouts the Future of Road Design?
Roundabouts are more than just a traffic trend—they are a safer, smarter, and greener solution for modern transportation. With their ability to reduce crashes, improve traffic flow, and lower emissions, they are quickly becoming a preferred alternative to traditional intersections.
🚗 Safer roads, fewer accidents
🚗 Smoother traffic, less congestion
🚗 Lower fuel costs, reduced pollution
As more states adopt roundabouts in urban and suburban planning, they will likely become a permanent feature of America’s roadways.
So next time you approach a roundabout, embrace the change—it’s making our roads safer and more efficient for everyone!
Meet Nyakim Gatwec, A Model That Was Dubbed ‘Queen Of The Dark’

The woman was shocked when her Uber driver uninvitedly offered advise on how to take care of her beautiful skin.
The “Queen of the Dark,” as the fashion diva was affectionately called, laughed off his comments and embraced her breathtaking beauty.
Continue reading to find out what this Uber driver said her and how she utilized it as a teaching moment!
Nyakim Gatwech, who spent her early years in refugee camps in Ethiopia and Kenya, thought that living in America would “be like heaven.”
But when Gatwech moved to Buffalo at the age of 14, she stayed by herself a lot, crying over comments made about her very dark skin tone.
“You don’t wash your hair. Because of this, your skin is filthy.Or, “Nyakim, smile so we can see you. You are invisible to us. You have dirty skin as a result. Or grin for us to see you, Nyakim. We cannot see you.
In class, for example, the instructor might ask a question and say, “Oh, Nyakim, can you answer that?””How about a toddler asking, “Who are you talking to?”? We cannot see her. She’s not here. The now 31-year-old woman says, “I would just cry, and the whole class would start laughing,” as reported by Cosmopolitan.
The innocent young girl just wanted to fit in, but it was difficult when random people were speculating about whether or not she was indeed that dark-skinned and whether or not she was wearing leggings.
I did think about [bleaching my skin] at one time. I was 14 years old when I fled an African refugee camp and moved to Buffalo, New York. The beauty admits, “After being teased [about my skin], I would cry myself to sleep.””So many stunning Sudanese women with dark skin tones bleach their skin.”
The model continued by saying that her own sister was one of the Sudanese ladies who had bleached her skin.”It was my own sister.” However, after a few months of living in America, I told her that I wanted to, and she said no. I will not allow my kid, you, or anyone else to do it.
Dark Queen
The woman, who has encountered prejudice from makeup artists, designers, and other models, is now referred to as the Queen of the Dark and feels strong since she has triumphed over the criticism.
Additionally, Gatwech’s 962,000 dedicated Instagram fans encourage her self-assurance and amazing fondness for her deep chocolate skin tone.
“My chocolate is sophisticated. Thus, I stand for this. A country of fighters,” she writes in one of her posts.
And the incredibly beautiful woman’s admirers can’t get enough of her.
One fan writes, “Omgggggg I love your skin and melanin,” while another exclaims, “I love your beautiful skin tone so much!” God creates exquisite things like you to serve as a constant reminder of His majesty.
In response to the tremendous outpouring of love, Gatwech adds, “I learned to love myself.I’m not troubled by the negative anymore. I love and embrace my skin, and I no longer feel insecure about it. I no longer believe I’m ugly. I am confident in who I am.
“The silliest queries”
Speaking about her odd skin, Gatwech recounts about meeting an Uber driver a few years ago who asked if she would ever consider whitening it.
“Oh, you’re dark,” he remarked.Gatwech describes her chat with the driver to Cosmopolitan.”I merely chuckled. I was curious as to why he felt that I ought to. He said that because it would make my life simpler. If I were lighter, I could get into a relationship more easily and guys would be more drawn to me. I’m lighter, so if I went to a job interview, I would receive the opportunity. I just responded, “I’d rather take the [hard] road, even if] being lighter would make my life easier.”
The woman goes on, “I’m used to people asking the stupidest questions ever [about my skin].”
Gatwech then shared the story on Instagram along with a stunning picture of herself with three other stunning dark-skinned Sudanese women.
“A country with people so dark you won’t believe your eyes,” the author writes. Teeth so brilliant, skin so rich. Oh, how I cherish my nation, my people, and all that it entails.
“[SIC] I was asking my Uber driver the other day, and he said, don’t take this personally, but would you bleach your skin for ten thousand dollars?” she says, going on to describe her interaction with the driver. I couldn’t even respond because I was laughing so much.He then responded, “So that’s a no,” to which I replied, “Hell to the f*king yeah, that’s a no, why would I ever bleach this gorgeous melanin that God bless with me?””So you see it as a blessing,” he continued.
Her backers applauded Gatwech right away and raced to her defense.
“I suppose he missed the memo.”Black is gorgeous,” an admirer writes.
Another person says, “I cherish you for cherishing me.”A third wonders, “Why would we ever want to mess up something so beautiful?”
Asking Yahoo Beauty for guidance, she said, “You are beautiful, you are unique, and there are people who love you just the way you are” to young black girls suffering comparable struggles. It’s said that the juice of a cherry is sweeter the darker it is. Accept your gloom!
