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!
Newly-unveiled statue of Queen Elizabeth II includes her beloved pet Corgis
A great deal of people felt sorrow upon Queen Elizabeth II’s passing in 2022. She was adored by the public and the longest-reigning monarch in British history, having ruled for 70 years.
The late queen is now being honored with a monument that was recently unveiled, honoring her affection for her pet corgis!
The Queen’s new statue, together with her dogs
On Sunday, a 7-foot-tall bronze statue of Queen Elizabeth was unveiled in observance of the monarch’s 98th birthday.
In Oakham, England, the sculpture was made by artist Hywel Pratley and is situated close to the Oakham Library. It is Queen Elizabeth’s first ever permanent memorial.
Rutland City Council said that hundreds attended the unveiling. There was music from local school bands and bagpipers.
The most priceless feature of this new memorial is that the queen’s cherished Corgis pet is also depicted, immortalized in bronze by the monarch’s feet:
The city authority claims that local schoolchildren created the designs for the Corgi monuments.
In contrast to the many stern and imposing monuments of queens like Queen Victoria, Pratley stated he wanted the statue to portray the idea of Queen Elizabeth as “an almost motherly figure,” according to the New York Times.
During the unveiling, local dignitary Sarah Furness remarked, “What most of us remember about Queen Elizabeth is her warmth.” “We demonstrate Queen Elizabeth’s humanity by showcasing her affection for dogs.”
The statue’s creator claims that he intended it to be hospitable to onlookers. Pratley said, “We designed it with a bench you can sit on.” “And there’s a corgi you can pet, and I do believe that this will eventually become a selfie-encouraging statue.”
The Times reports that a number of Corgi owners brought their dogs to the unveiling, indicating that a large number of people have already visited the statue.
The history of Queen Elizabeth’s Corgis pet
For many years, the Queen’s corgis were an iconic aspect of her life and a solace during tough political and personal times. Fans all throughout the world were likewise pleased by the cute pets.
The first Corgi was acquired by the royal family in 1933 when Dookie, a dog owned by Elizabeth’s father and predecessor George VI (who was then the Duke of York), was brought home.
Dookie was reportedly extremely cantankerous, yet Elizabeth and him appeared to have a unique relationship.
Then, on her eighteenth birthday, the Queen received a Pembroke Welsh corgi of her own, named Susan.
Susan reportedly slipped under a rug in the royal carriage to disrupt the wedding of the Queen and her husband, Prince Philip, according to the BBC.
1959 saw Susan’s death at the age of almost fifteen. Her epitaph referred to her as “the faithful companion of the Queen,” and she was laid to rest at the royal estate of Sandringham House.
The Queen stated, “I had always feared losing her, but I am ever so thankful that her suffering was so mercifully brief.”
But Susan left quite the legacy; during the ensuing few decades, the Queen accumulated over thirty corgis, all descended from her original canine companion.
The Queen always had at least one corgi, and often had several at once, from 1933 until 2018. She traveled with the dogs in tow, and they resided in a designated “Corgi room” at Buckingham Palace with wicker beds. It is said that the Queen took care of them personally and baked them biscuits over the holiday season.
These canines undoubtedly received royal treatment and grew to represent the Queen throughout her life.
While Elizabeth valued the dogs greatly, Prince Philip apparently didn’t feel the same way. Like many others, she took great solace from the dogs, who served as a link to the simpler times in her early years due to their relationship with her late father and her upbringing.
According to Penny Junor, a royal biographer, “her corgis are hugely important to her.” Over time, they have become more intimate with her than any human has ever been. She has never been let down by the incredibly affectionate and devoted corgis.
It also makes sense that the Queen, who represents both Britain and the United Kingdom, would have a strong bond with a quintessential British dog. Wales, a member of the UK and a neighbor of England, is where corgis first originated. When corgis were adopted as royal dogs, the breed was rare in England; yet, the Queen had a major role in the globalization of the breed.
The Queen owned several “dorgis,” or corgis bred with daschshunds, in addition to purebred Pembroke Welsh Corgis.
When the corgis and dorgis appeared alongside Queen Elizabeth on the cover of Vanity Fair in 2016, they became well-known worldwide because to Annie Leibovitz’s photography. At the time, the dogs were Candy, Vulcan, Willow, and Holly.
A notable aspect of Queen Elizabeth’s reign and a significant aspect of her life were her corgis. Their inclusion in this first memorial statue of her seems so fitting.
