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!
My Dad Who Left 20 Years Ago Called from His Deathbed for a Final Wish — What He Asked Broke My Heart
My Dad Who Left 20 Years Ago Called from His Deathbed for a Final Wish — What He Asked Broke My Heart
When my estranged father, who left 20 years ago, called from his deathbed, I was torn between anger and curiosity. His final wish was something I never expected, and what he revealed about his disappearance shattered everything I thought I knew.
I was getting ready for bed when my phone buzzed on the nightstand. The number was unfamiliar, so I let it go to voicemail. Not even a minute later, a text came through: “ALICE, THIS IS YOUR DAD. PLEASE CALL, I AM IN THE HOSPITAL.”

My heart stopped. Dad? After twenty years? I sat on the edge of my bed, staring at the message. Part of me wanted to delete it and forget, but curiosity won. I called the number back.
“Hello?” The voice was weak, barely audible.
“Dad?”
“Alice, it’s me. I… I don’t have much time.”
“Why are you calling now?” My voice was harsher than I intended.
“I need to explain… to ask something of you. But please, don’t tell your mother.”

There it was, the same secrecy that defined my childhood. “What do you want?”
He took a shaky breath. “I left because your grandfather, Harold, paid me to disappear. He hated me, thought I was a failure. He found someone else for your mom, someone better.”
I couldn’t believe what I was hearing. “Grandpa? He did that?”
“Yes. I was struggling back then. Addictions, bad decisions. Your grandfather saw a chance to get rid of me, and I took the money.”

“So you just left us for money?” Anger bubbled up.
“I know it sounds awful. But I invested that money, built a business. It was all for you, Alice. To secure your future.”
“Why didn’t you ever come back?”
“Part of the deal. I couldn’t approach you or your mom. But I was there, watching. I saw your graduation, your volleyball games. I was always there, just… from a distance.”
I felt like my world was tilting. “Why didn’t Mom ever tell me?”

“I don’t know. Maybe she didn’t want you to hate him. Or maybe she thought she was protecting you.”
“What do you want now?” I asked, my voice trembling.
“I need to see you, Alice. One last time before I go. I’m at St. Mary’s Hospital.”
I didn’t know what to say. Could I face him after everything?
“Please, Alice. It’s my dying wish.”

The line went silent, and I sat there, the phone still in my hand, my thoughts tumbling. Should I go? What would I even say to him? I needed to think, but there was no time. He was dying.
The next morning, I called in sick to work and sat in my kitchen, staring at my coffee. Should I tell Mom? But he’d asked me not to.
I called my best friend, Jen. “Hey, can we talk?”
“Of course. What’s up?”

“It’s… it’s my dad. He called last night.”
“Your dad? The one who left?”
“Yeah. He’s dying, and he wants to see me.”
“Wow. How do you feel about that?”
“I don’t know. Angry, confused. He told me things, Jen. About my Grandpa.”
“Like what?”
“That my grandfather paid him to leave. He said he was there at my graduation, my games. But he couldn’t approach us.”
“That’s insane. What are you going to do?”
“I don’t know. He wants me to visit him, but I’m not sure I can.”

Jen was silent for a moment. “Maybe you should go. Get some answers. Closure.”
“I guess. But I don’t know if I’m ready to face him.”
“Take your time, but don’t take too long. If he’s dying…”
“I know. Thanks, Jen.”
After hanging up, I sat back, deep in thought. Jen was right. Maybe I did need closure. I couldn’t keep living with these unanswered questions. And if he really was dying… I had to see him.

I decided to go to the hospital. As I drove, memories of my childhood flashed through my mind. The good times before he left, the confusion and pain afterward. The way Mom never spoke about him, the unanswered questions that haunted me.
I walked into the hospital room, feeling the weight of years and unanswered questions pressing down on me. The beeping machines filled the stark room with an unsettling rhythm. My dad lay in the bed, looking more frail than I had ever imagined. His eyes lit up when he saw me, a weak smile forming on his lips.

“Alice,” he whispered, his voice barely audible.
“Hi, Dad.” I stood at the foot of the bed, not sure what to say. Anger and confusion swirled inside me, but seeing him like this, so vulnerable, made it hard to voice them.
“You came,” he said, relief evident in his eyes.
“I had to. I needed to understand why.”
“I know, and I’m so sorry for everything.” He reached out a trembling hand, and I took it, feeling the cold, fragile skin.

“Why did you do it, Dad? Why did you take Grandpa’s money and leave us?”
He sighed, a deep, rattling sound. “I thought it was the best way to secure a future for you and your mother. I was a mess, Alice. Addicted, broke. Your grandfather offered me a way out, a chance to give you a better life, even if it meant I couldn’t be part of it.”
“Do you know how much that hurt us? How much it hurt me?” Tears welled up in my eyes. “You missed everything, Dad. My graduation, my volleyball games, my entire life.”

“I was there, Alice. Watching from afar. It broke my heart not to be with you, but I thought I was doing the right thing.” He paused, struggling for breath. “I tried to make it right. I invested the money, built something that I hoped would help you.”
“Why didn’t you come back when you were better?”
“I couldn’t. Part of the deal was that I had to stay away. But I wrote to you, Alice. Letters, every year. They’re in a safety deposit box. Here.” He handed me a small key. “After I’m gone, open it. You’ll find proof of everything, and the letters.”

I took the key, my fingers trembling. “Why now, Dad? Why tell me all this now?”
“Because I’m dying, and I can’t leave this world without you knowing the truth. I love you, Alice. I’ve always loved you.”
Tears streamed down my face as I gripped his hand. “I needed you, Dad. I needed my father.”
“I know, and I’m so sorry I wasn’t there. But I hope you’ll understand why I did what I did when you read those letters.”

We sat in silence, holding hands, the machines’ beeping the only sound in the room. After a while, his breathing became more labored. He squeezed my hand one last time, and then he was gone.
I left the hospital feeling a mix of emotions. Relief, anger, sadness, and a strange sense of closure. The next day, I went to the bank and used the key to open the safety deposit box. Inside, I found stacks of financial documents and a bundle of letters, each one addressed to me, dated over the years.

I took the letters home and spent hours reading them. Each one was filled with his regrets, his love, his hopes for my future. He wrote about the business he built, how he watched over me, how proud he was of my achievements.
By the time I finished the last letter, my anger had softened into a deep, aching sadness.
With the financial documents, it was clear that my father had indeed worked hard to secure my future. The money he left behind was substantial, enough to change my life. But it wasn’t just about the money. It was about understanding his choices, his sacrifices, and his love.

I knew I had to talk to my mom. I needed to know her side of the story. When I confronted her, she looked at me with sad eyes.
“I knew about the offer,” she admitted. “I didn’t stop it because I thought it was best for you too. I thought you deserved a better life than what your father could give you at that time.”
“Why didn’t you ever tell me?”
“I wanted to protect you from the truth, to let you remember him without bitterness. Maybe I was wrong, but I did what I thought was best.”

Her confession was another piece of the puzzle, helping me to understand the complex web of decisions that shaped my life.
In the end, I decided to use the money to start a scholarship fund in my father’s name. It felt like the right way to honor his memory and his efforts. It was a way to help others, just as he had tried to help me.
As I launched the scholarship, I felt a sense of peace. The past was complicated and painful, but it had brought me to where I was. And now, with the truth out in the open, I could move forward, honoring both my father’s love and my mother’s sacrifices.
