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!
10 Little-Known Mistakes in Pretty Woman That Will Blow Your Mind
Pretty Woman is one of those movies I can watch over and over — it never gets old or boring.
But considering how many times I’ve seen it, it’s surprising that I’ve never noticed these bloopers and mistakes that tell a different story about the film.
Disney changed everything
*Pretty Woman* became a romantic comedy that captured millions and launched Richard Gere and Julia Roberts to fame.
But that’s not how it was originally meant to be. The first screenplay was titled *3,000*, written by then-struggling screenwriter J.F. Lawton. The early draft dealt with much darker themes about social inequality and corporate greed.
However, everything changed when Disney took over. The company chose to downplay the themes of class and sex work in Los Angeles. Instead, Disney gave it a big budget and turned it more into a romantic comedy.
Al Pacino turned down the lead role
For me, it’s hard to imagine anyone but Richard Gere as Edward Lewis, the wealthy businessman from New York who hires Vivian (Julia Roberts) to be his escort for a week.
The casting process for *Pretty Woman* took longer than expected, with Al Pacino initially in the running for the role of Lewis. The famous actor even took part in a casting reading with Julia Roberts but ultimately decided to pass on the part.
Although he liked the script, Pacino never explained why he turned it down. Looking back, he has shown respect for Roberts, who was a relatively unknown actress at the time.
“I mean, you could tell at the reading that this was going to be good, that it would be a hit,” Pacino said.
He also mentioned: “And this girl was amazing. I asked Gary, ‘Where did you find this girl?’” (Gary being Gary Marshall, the film’s director). Pacino’s instincts were right, as Roberts’s outstanding performance would shape her career and the film’s legacy.
The croissant becomes a pancake
In the scene where Richard Gere’s character orders breakfast in the room, there’s a funny little detail you might not have noticed. It starts with Vivian enjoying a croissant while talking to Edward.
But then, in an instant, the croissant magically turns into a pancake.
How did that happen? According to director Garry Marshall, he liked Julia Roberts’ performance in the later takes, where she was eating a pancake instead of the croissant, so they decided to use that footage.
However, this caused a continuity issue. In the first shot with the pancake, Vivian takes a second bite, but in the next shot, the pancake only has one bite missing, and the bite marks are clearly different.
It’s clearly not the same pancake!
Truth behind the iconic dress
The careful attention to costume design might go unnoticed by most moviegoers. However, whether you notice fashion or not, it’s hard to miss the iconic red dress that Julia Roberts’ character wears in the film.
The red dress represents Vivian’s transformation and empowerment during a key scene in the movie when Roberts’ character joins Edward Lewis for a night at the opera.
Vogue described the dress as “eye-catching, incredibly sexy without losing any elegance.” The genius behind that stunning dress? The award-winning costume designer Marilyn Vance.
She created six fabulous outfits for Julia Roberts’ character, Vivian Ward, and also designed Richard Gere’s stylish looks.
For example, the charming brown-and-white polka dot dress Roberts wore to the horse race was made from old silk found in a small antique fabric shop in Los Angeles — talk about recycling in style! And those chic shoes? They were by Chanel.
Richard Gere’s tie
As for Gere’s wardrobe, it was a masterclass in color coordination, featuring brown, navy, and blue-gray suits, all designed by Vance.
Now, about that famous tie that Roberts takes from a store employee? According to Vance, it was “nothing special” and definitely not a designer piece.
She bought it in a Los Angeles shop for $48.
The tie appears several times in the film, and if you watch closely, you might notice that it mysteriously changes knots from time to time.
During the polo match, Edward wears a straight-collar shirt with the tie that Vivian gave him, knotted in a half-Windsor. But in a later scene, sharp-eyed viewers can see a subtle change — Edward’s collar has turned into a spread style, and the tie is now in a full-Windsor knot.
‘Obscene’ shopping spree
When Richard Gere shows Julia Roberts’ character the glamorous world of the rich, he takes her on a wild shopping spree down Rodeo Drive in Beverly Hills.
That afternoon shopping trip? It would have cost Gere’s character at least $30,000, according to designer Marilyn Vance.
Talk about a shopping spree on steroids! It’s like they were shopping with Monopoly money — no wonder Vivian was in a daze.
The ruby-and-diamond necklace was real
The jewelry Julia Roberts wore with her stunning red ball gown — a heart-shaped necklace made of rubies and diamonds — was valued at an incredible quarter million dollars. Yes, you heard that right.
According to movie trivia sites, this ruby-and-diamond masterpiece was the real deal. In fact, while filming, an armed security guard from the jewelry store responsible for this extravagant necklace stood watch behind the director.
Jewelry box scene was a practical joke
The scene where Richard Gere gives Julia Roberts the expensive necklace is not only one of the most romantic and iconic moments in movie history, but it also has a funny backstory.
Originally, it was meant as a playful prank for the film’s gag reel.
As you might remember, the jewelry box snaps shut on Julia Roberts’ fingers, causing one of the most genuine and charming laughs ever caught on film.
The real story behind the scene came from director Garry Marshall, who explained why he and Gere decided to play this trick on the young actress.
According to Marshall, Roberts, who was just 23 at the time, would sometimes show up on set a little sleepy after a late night out.
“I said, ‘Richard, you gotta wake her up a little, so when she reaches for the box, slam it.’ It was a soft box. I would never hurt her,” Marshall explained.
It wasn’t until the final stages of editing that they decided to keep the scene in the movie. “We put it in… and it became like the trademark of the movie,” Marshall said.
And just like that, an unscripted joke turned into cinematic magic.
Edward’s disappearing shoes
As mentioned earlier, there are some mistakes in *Pretty Woman* that aren’t easy to spot on the first viewing, but some keen viewers have noticed them.
For instance, when they leave the opera and head to the park, Vivian takes off Edward’s shoes. However, as he begins to lie down, the shoes magically reappear.
Money in the boot
Speaking of things on (or in) your feet, there’s a little mystery involving Vivian’s boots that you might have missed.
When Edward gives her $100 in the penthouse, she slips the cash right into her boot for safekeeping. But later, after room service arrives with champagne and she takes off her boots, the money has mysteriously disappeared.
Did the cash vanish into thin air, or is Vivian just really good at hiding things? Maybe those boots had a secret compartment, or perhaps the $100 simply didn’t want to stick around for the rest of the film…
Four colored condoms
When Vivian offers Edward a selection of colorful condoms, it seems they have a mind of their own.
Vivian starts with four neatly arranged options (not counting that fancy gold circle one). But in the next shot, the order has magically changed.
Richard Gere didn’t like his character
Richard Gere has certainly gained from the success of *Pretty Woman*—both in his career and his bank account. But he hasn’t always been fully positive about the film, especially regarding his character, Edward. At a film festival in Venice, Gere described Edward as “criminally underwritten.” He added, “Basically, he’s just a suit and a good haircut.”
One scene in particular seemed to bother Gere, where Edward plays the piano while Vivian moves closer. Reflecting on it, Gere sarcastically said, “I mean, no chemistry. This actor and this actress obviously had no chemistry between them… I haven’t seen that in a long time. That’s a sexy scene.”
Director Garry Marshall came up with the idea for the scene after asking Gere what he usually did late at night in a hotel. Gere remembered, “I said, ‘Well, I’m usually jet lagged, so I’m up all night. Usually, there’s a ballroom or a bar, and I’ll find a piano and play it.’” Marshall then suggested, “Well, let’s do something with that.”
So, the scene was mostly improvised, with Gere explaining: “He said, ‘Play something moody.’ I just started playing something moody that reflected this character’s interior life.”
Then, just as mysteriously, the original lineup of condoms snaps back in the third shot. It’s as if the condoms were having their own little dance routine behind the scenes.
More than just onscreen lovers
If you ask me, the chemistry between Julia Roberts and Gere in *Pretty Woman* was undeniable. But the sparks didn’t just fly when the cameras were rolling — they formed a close bond off-screen too.
In 2017, Gere shared that he still talks to Roberts “all the time,” and back in the day, they would chat “three or four times a day.”
You could say it was love at first sight, in a friendly sort of way.
Even in a fairytale romance, things don’t always go as planned. Maybe that’s what makes this movie so charming and keeps us watching it again and again, year after year.
