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!
Man Bans Poor Old Mom from Seeing Her Newborn Grandson after She Walks for Hours to Do So – Story of the Day
Amelia wanted to meet her newborn grandson, but when her son, Mark, wouldn’t pick her up, she decided to walk to his house. It took hours because she was using a walker. But when she got to Mark’s house, he banned her from entering, and something shocking happened.
“I can’t pick you up, Mom. I have to run some errands for Camilla, and other people are coming. We’ll set a time for you to see the baby,” Mark told his mother, Amelia, on the phone. She was supposed to come to see their newborn baby for the first time, and he had to pick her up because his house was far away.
“Are you sure? It’s pretty quick by car,” Amelia almost pleaded. She truly wanted to meet her grandson.
“Some other time, Mom. I have to go. See you later!” he hung up, and Amelia plopped down on her couch with a huge sigh.
“I don’t care what you brought! I don’t want you here right now. You need to go immediately!”
She was worried about Mark’s attitude lately. It seemed like he had been pulling away from her. If she was being honest, it started happening when he married Camilla.
Camilla came from an extremely wealthy family in Connecticut, while Amelia raised Mark as a single mother with the help of his grandmother. They never had much except tons of love. But now, her son had everything. Camilla’s parents gifted them a huge house after they eloped, and he was living the high life.
Ever since then, Amelia felt left out, as if he was ashamed of his background, although he never said it outright.
“You’re being silly,” she told herself often when she thought about this matter. “Mark is just busy. Now they have a baby and a million things to do. He’ll pick you up some other time.”
But she had a sudden idea. She could walk to his house. It might be challenging, but she could do it. The bus routes didn’t reach his home, and she couldn’t afford it, so walking was her only option.
She finally reached his house and rang the door bell. | Source: Pexels
Amelia heaved herself up with her walker and grabbed her purse and a bag she had prepared for that day. She hung them on the walker securely and started her journey. It was slow, and although she could lean on the walker, it was tough on her.
She had to stop several times along the way, and before she knew it, two hours had passed. Three. Four. Finally, she reached his house, heaving heavily but happy that she had done it even with her walking issues.
After ringing the doorbell, she took the special bag as she wanted Mark to open it right away. But when he answered the door, his face fell.
“Mom?” he said, shocked. “What are you doing here?”
Amelia didn’t understand his expression and almost frowned, but she was was excited to be there and that’s what she focused on. “Surprise!” she said, trying to sound enthusiastic although she was tired, hungry, and concerned about his attitude.
Mark stepped out, closing the door behind him and forcing her to take several steps back with her walker. “What are you doing, Mark?” she asked, frowning now.
“Mom! I told you you would meet the baby some other time. You can’t come in right now!” he scolded her, his face crumpled in anger.
Mark was angry and told her to go away, shutting the door in her face. | Source: Pexels
“I don’t understand. Why are you angry? I just walked almost five hours to see my grandson, Mark, and I brought—”
“I don’t care what you brought! I don’t want you here right now. You need to go immediately! You’ll meet Hans another day, alright? Please just go now!” he demanded, looking behind him as if worried that someone would see them. He opened the door and returned inside, shutting the door in her face and leaving her standing outside with her things.
Amelia was shocked. Tears gathered in her eyes. He didn’t even ask if she was alright, although she had just told him about walking for five hours to get there. He knew she had problems with mobility.
But she didn’t want to cause any more trouble, so she started to turn around, then she remembered the bag in her hands. She decided to leave it outside his door, hoping he would find it later.
Amelia set out to walk home, prepared for the long, tiring hours that lay ahead. Luckily, her neighbor, Mrs. Cassavetes, saw her and gave her a ride in her old car. When she arrived home, her legs gave out as soon as she closed her front door. She sat down on the couch, and that’s when she noticed her legs were inflamed.

After some rest, she managed to stand up, get some ice, and take a pain reliever. But in the end, she had to sleep on the sofa because her bedroom seemed too far away.
***
Meanwhile, Mark said goodbye to his guests that night, waving at them through his front door. It had been a hectic day with many visitors, and it was finally over. He hunched his shoulders, thinking about his actions earlier that day.
His mother had walked to his house from her own home, he thought guiltily, then shook his head, convincing himself that it was not his fault.
“She shouldn’t have done that,” he whispered to himself. As he turned around, he noticed the bag on the floor. He picked it up and saw a tag labeled, “From Grandma.”
Mark bit his lip, thinking about his mother leaving it there and returning to her house. He opened the bag and realized what was inside. They were his old toys from his childhood. They never had much at his house, but these items were always precious to him. They still were. He couldn’t help but start crying.
Camilla saw him outside and got worried. “What’s wrong, honey?”
He went to her house and entered with his set of keys. | Source: Pexels
“I did something horrible to my mother,” he wailed, and his wife embraced him. He revealed everything he had done, including that he started pulling away from his family because they were all poor, and he felt ashamed. “I can’t believe I was so horrible to her!”
After his wife comforted him, Mark decided to drive to his mother’s house immediately with a big apology. He still had the keys to her house in case of emergencies, so when he got there, he decided not to ring the doorbell and just use them to get in. But he was greeted by the vision of his mother passed out on the couch with cold compresses on her legs.
“Mom,” he whispered, waking her up gently.
“Mark, why are you here?” she said groggily and tried to get up, but he stopped her.
“Don’t move,” he said and picked up his mother as if she weighed nothing, moving her to her bedroom. He added more ice to her cold compresses and helped her put them on her swollen legs. He also made her something to eat, and they drank tea together. Then he apologized for his attitude and told her the truth.

Luckily, his mother was the most fantastic person in the world. “I had a feeling you were ashamed, but I’m glad you came here right away to apologize. That’s what I taught you. When you do something wrong, you have to make things right,” Amelia reassured him, and Mark cried into her arms for some time.
He stayed with her the entire night, and fortunately, her legs were much better. The next morning, they decided to go to his house so she could meet his new baby, Hans.
Camilla also apologized because she had no idea what Mark did, but she should’ve asked why Amelia was not there. They spent a wonderful day together, and Amelia gave Camilla tons of advice about babies.
Eventually, Mark asked his mother to move in with them because they had a huge house, and he didn’t want her to be all alone so far away.
What can we learn from this story?
- Never be ashamed of your parents. Mark felt embarrassed about his background and tried to keep it from Camilla’s family, hurting his mother in the process. He regretted it later.
- It’s best to make things right when you realize you made a mistake. Mark immediately tried to make things right after realizing his horrible mistake against his mother. Luckily, she forgave him quickly.
