After all the heartbreak, Jason Momoa found new love, and you’ll surely recognize her

About two years following his formal divorce from his ex-wife Lisa Bonet, Jason Momoa revealed his new relationship to the public. On Tuesday, May 21, he and actress Adria Arjona were seen cuddling on the PDA. They had declared their romance official on Instagram two days earlier.

When Momoa told fans he had been dating for a while during his appearance at the Basingstoke Comic Con in England in early May of this year, many began to speculate that the two were dating. “I’m in a relationship rather seriously. He said to the assembly, “I’ve been in a relationship for a time. “I’m really enjoying [my] privacy because everyone gives a fuck these days, whereas nobody did back in the day.”

The Aquaman star shared a number of pictures with Arjona recently, including some from their vacation to Japan. One of the photos shows the two on a beach, grinning. He tenderly referred to Arjona as “mi amor” in the post.

“You are a dream come true, Japan—you completely amazed me. We are very appreciative of everyone who opened their houses, allowing us to create memories with both old and new friends and go on yet another incredible journey with our beloved. Motorcycles and chaos on the road. All of my love, J,” the performer wrote.

Arjona herself has a Hollywod background. She has a number of noteworthy appearances, including those in Life of the Party, Pacific Rim Uprising, and a regular character in True Detective. Her breakout role was that of Dorothy Gale in the Emerald City adaption of the Oz book.Despite the fact that the show was canceled after just one season, she has since landed many important parts.

makes an appearance in the recently released comedy-action Netflix film Hit Man, which stars Glen Powell and was directed by Richard Linklater.

Momoa’s stepdaughter from his marriage to Bonet, Zoë Kravitz, directed Blink Twice, one of her most recent ventures.

Edgardo Canales, a lawyer, was Arjona’s husband. They had a private relationship, and no information about their breakup has been made public.

Momoa dated Eiza González for a few months in 2022 prior to Arjona.

The new pair appeared in the 2021 Netflix original series Sweet Girl together.

What are roundabouts? A transportation engineer explains the safety benefits of these circular intersections

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

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

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!
