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.

- 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 Husband Made a Schedule to ‘Improve’ Me as a Wife — I Taught Him a Valuable Lesson Instead
I was stunned when my husband, Jake, handed me a schedule to help me “become a better wife.” But instead of blowing up, I played along. Little did Jake know, I was about to teach him a lesson that would make him rethink his newfound approach to marriage.
I’ve always prided myself on being the level-headed one in our marriage. Jake, bless his heart, could get swept up in things pretty easily, whether it was a new hobby, or some random YouTube video that promised to change his life in three easy steps.
But we were solid until Jake met Steve. Steve was the type of guy who thought being loudly opinionated made him right, the type that talks right over you when you try to correct him.
He was also a perpetually single guy (who could have guessed?), who graciously dispensed relationship advice to all his married colleagues, Jake included. Jake should’ve known better, but my darling husband was positively smitten with Steve’s confidence.
I didn’t think much of it until Jake started making some noxious comments.
“Steve says relationships work best when the wife takes charge of the household,” he’d say. Or “Steve thinks it’s important for women to look good for their husbands, no matter how long they’ve been married.”
I’d roll my eyes and reply with some sarcastic remark, but it was getting under my skin. Jake was changing. He’d arch his eyebrows if I ordered takeout instead of cooking, and sigh when I let the laundry pile up because, God forbid, I had my own full-time job.
And then it happened. One night, he came home with The List.
He sat me down at the kitchen table, unfolded a piece of paper, and slid it across to me.
“I’ve been thinking,” he started, his voice dripping with a condescending tone I hadn’t heard from him before. “You’re a great wife, Lisa. But there’s room for improvement.”
My eyebrows shot up. “Oh really?”
He nodded, oblivious to the danger zone he was entering. “Yeah. Steve helped me realize that our marriage could be even better if you, you know, stepped up a bit.”
I stared at the paper in front of me. It was a schedule… and he’d written “Lisa’s Weekly Routine for Becoming a Better Wife” at the top in bold.
This guy had actually sat down and mapped out my entire week based on what Steve — a single guy with zero relationship experience — thought I should do to “improve” myself as a wife.
I was supposed to wake up at 5 a.m. every day to make Jake a gourmet breakfast. Then I’d hit the gym for an hour to “stay in shape.”
After that? A delightful lineup of chores: cleaning, laundry, ironing. And that was all before I left for work. I was supposed to cook a meal from scratch every evening and make fancy snacks for Jake and his friends when they came over to hang out at our place.
The whole thing was sexist and insulting on so many levels I didn’t even know where to start. I ended up staring at him, wondering if my husband had lost his mind.
“This will be great for you, and us,” he continued, oblivious.
“Steve says it’s important to maintain structure, and I think you could benefit from —”
“I could benefit from what?” I interrupted, my voice dangerously calm. Jake blinked, caught off guard by the interruption, but he recovered quickly.
“Well, you know, from having some guidance and a schedule.”
I wanted to throw that paper in his face and ask him if he’d developed a death wish. Instead, I did something that surprised even me: I smiled.
“You’re right, Jake,” I said sweetly. “I’m so lucky that you made me this schedule. I’ll start tomorrow.”
The relief on his face was instant. I almost felt sorry for him as I got up and stuck the list on the fridge. Almost. He had no idea what was coming.
The next day, I couldn’t help but smirk as I studied the ridiculous schedule again. If Jake thought he could hand me a list of “improvements,” then he was about to find out just how much structure our life could really handle.
I pulled out my laptop, opened up a fresh document, and titled it, “Jake’s Plan for Becoming the Best Husband Ever.” He wanted a perfect wife? Fine. But there was a cost to perfection.

I began by listing all the things he had suggested for me, starting with the gym membership he was so keen on. It was laughable, really.
“$1,200 for a personal trainer.” I typed, barely containing my giggle.
Next came the food. If Jake wanted to eat like a king, that wasn’t happening on our current grocery budget. Organic, non-GMO, free-range everything? That stuff didn’t come cheap.
“$700 per month for groceries,” I wrote. He’d probably need to chip in for a cooking class too. Those were pricey, but hey, perfection wasn’t free.
I leaned back in my chair, laughing to myself as I imagined Jake’s face when he saw this. But I wasn’t done. Oh no, the pièce de résistance was still to come.
See, there was no way I could juggle all these expectations while holding down my job. If Jake wanted me to dedicate myself full-time to his absurd routine, then he’d have to compensate for the loss of my income.
I pulled up a calculator, estimating the value of my salary. Then, I added it to the list, complete with a little note: “$75,000 per year to replace Lisa’s salary since she will now be your full-time personal assistant, maid, and chef.”
My stomach hurt from laughing at this point.
And just for good measure, I threw in a suggestion about him needing to expand the house. After all, if he was going to have his friends over regularly, they’d need a dedicated space that wouldn’t intrude on my newly organized, impossibly structured life.
“$50,000 to build a separate ‘man cave’ so Jake and his friends don’t disrupt Lisa’s schedule.”
By the time I was done, the list was a masterpiece. A financial and logistical nightmare, sure, but a masterpiece nonetheless. It wasn’t just a counterattack — it was a wake-up call.
I printed it out, set it neatly on the kitchen counter, and waited for Jake to come home. When he finally walked through the door that evening, he was in a good mood.
“Hey, babe,” he called out, dropping his keys on the counter. He spotted the paper almost immediately. “What’s this?”
I kept my face neutral, fighting the urge to laugh as I watched him pick it up. “Oh, it’s just a little list I put together for you,” I said sweetly, “to help you become the best husband ever.”
Jake chuckled, thinking I was playing along with his little game. But as he scanned the first few lines, the grin started to fade. I could see the wheels turning in his head, the slow realization that this wasn’t the lighthearted joke he thought it was.
“Wait… what is all this?” He squinted at the numbers, his eyes widening as he saw the total costs. “$1,200 for a personal trainer? $700 a month for groceries? What the hell, Lisa?”
I leaned against the kitchen island, crossing my arms.
“Well, you want me to wake up at 5 a.m., hit the gym, make gourmet breakfasts, clean the house, cook dinner, and host your friends. I figured we should budget for all of that, don’t you think?”
His face turned pale as he flipped through the pages. “$75,000 a year? You’re quitting your job?!”
I shrugged. “How else am I supposed to follow your plan? I can’t work and be the perfect wife, right?”
He stared at the paper, dumbfounded.
The numbers, the absurdity of his own demands, it all hit him at once. His smugness evaporated, replaced by a dawning realization that he had seriously, seriously messed up.
“I… I didn’t mean…” Jake stammered, looking at me with wide eyes. “Lisa, I didn’t mean for it to be like this. I just thought —”
“You thought what? That I could ‘improve’ myself like some project?” My voice was calm, but the hurt behind it was real. “Jake, marriage isn’t about lists or routines. It’s about respect. And if you ever try to ‘fix’ me like this again, you’ll be paying a hell of a lot more than what’s on that paper.”
Silence hung in the air, thick and uncomfortable. Jake’s face softened, his shoulders slumping as he let out a deep sigh.
“I’m sorry,” he whispered. “I didn’t realize how ridiculous it was. Steve made it sound sensible, but now I see it’s… it’s toxic. Oh God, I’ve been such a fool.”
I nodded, watching him carefully. “Yes, you have. Honestly, have you looked at Steve’s life? What makes you think he has the life experience to give you advice about marriage? Or anything else?”
The look on his face as my words hit home was priceless.
“You’re right. And he could never afford to live like this.” He slapped the list with the back of his hand. “He… he has no idea about the costs involved, or how demeaning this is. Oh, Lisa, I got carried away again, didn’t I?”
“Yes, but we’ll recover. Now, let’s tear that paper up and go back to being equals.”
He smiled weakly, the tension breaking just a little. “Yeah… let’s do that.”
We ripped up the list together, and for the first time in weeks, I felt like we were back on the same team.
Maybe this was what we needed, a reminder that marriage isn’t about one person being “better” than the other. It’s about being better together.
