Ynysforgan Roundabout named one of the UK’s most stressful junctions

A new study has revealed the most stressful road junctions for drivers, both in the UK and around the world – with Ynysforgan Roundabout in Swansea ranking among the top 10 in the UK and the top 20 worldwide! 

The study surveyed 1,000 UK drivers and asked them to rank road layouts based on the feelings of confusion, anxiety, fear and confidence that they felt after seeing images of the junctions from both a satellite and street view perspective. These responses were then used to build a unique ‘Stress Score’ out of 100 and reveal the road layouts that most drivers would rather avoid. 

The UK’s Most Stressful Junctions Revealed 

Among UK road layouts, London’s Hanger Lane Gyratory was rated the most stressful to navigate. One of the most complex and infamous junctions in the nation’s capital, the confusing layout, high accident rate and bottleneck for traffic make it one that many drivers would much rather avoid. 

The infamous Magic Roundabout in Swindon followed closely behind in second position, with a stress score of 42 out of 100. A multi-mini roundabout system, the roundabout is made up of five mini roundabouts arranged in a circle around a central island. Though the mini roundabouts are all driven in a standard clockwise movement, it is possible to navigate the central island in an anticlockwise direction.

The World’s Most Stressful Junctions for Drivers 

Meskel Square Roundabout in Ethiopia’s capital Addis Ababa is the junction that evokes the most stressed response among drivers, scoring 56 out of 100. Meskel Square is a major public space in the city but also connects some of the most major roads in the city, making it one of the busiest junctions too. Though it appears chaotic thanks to the lack of road markings, it’s reported to be a surprisingly functional junction, with drivers relying on intuition, eye contact and horn beeping as well as a healthy dose of mutual understanding. However, for any British drivers who are very used to traffic lights and road markings, it’s easy to see why it would be intimidating at a first look!

The Judge Harry Prengerson Roundabout in Los Angeles places in second spot, scoring 51 out of a possible 100 overall, just five points behind first place. With eight major traffic levels in a stacked multi-level formation that stands at more than 40 metres high, it’s quite the junction! It’s one of the few interchanges in the U.S. that offers full directional access, meaning that traffic entering in all directions, can also leave in all directions. Due to its size and layout, it can be quite nerve wracking for drivers to navigate, resulting in the high stress score.

Paris’ Arc de Triomphe roundabout follows in third, also scoring 51 on the Stress Score. Officially called the Place Charles de Gaulle, the roundabout is without doubt one of the most famous, and notorious, in the world. Found at the northwestern end of the Champs-Élysées, 12 major avenues all meet at this point, and similar to the Meskel Square roundabout, there are no road markings to allow vehicles to freely navigate their way through. To make matters more confusing, priority is given to the cars entering the roundabout rather than those already on it – the reverse of what we’re usually taught!

The Newark Airport Interchange in Newark, USA places in fourth spot, with Place de la Bastille Roundabout in Paris also making the top five with a score of 48.

Overall, European junctions make up half of the top 10, with three North American junctions also placing in the top flight. Japan’s iconic Shibuya Crossing places top for Asia, though in reality, it may be easier for drivers to navigate than expected, thanks to the 90-second window that allows traffic to flow, before the strict pedestrian-only phase.

Matt Clamp, Customer Service Manager at Scrap Car Comparison, commented: “Driving through unfamiliar junctions can rattle even the most experienced motorists. Junctions often combine high traffic volumes, poor signage and confusing layouts, making preparation essential. 

“Our advice? Start by planning ahead, tools such as Street View or route planners can help you visualise the road before you set off. Once you’re behind the wheel, try to get into the correct lane early by watching for signs and markings. If you start to feel overwhelmed, take a breath and don’t let other road users rush you – it’s perfectly okay to go at your own pace. 

“Always signal clearly and confidently to show your intentions, especially if you need to change lanes. And if you’re really nervous, consider driving at quieter times of day when the roads are less busy. A little preparation can go a long way in turning a potentially stressful drive into a safe and confident journey.”

Welsh Government says it will look again at Swansea M4 junction improvements

Welsh Conservative Member of the Senedd for South Wales West, Tom Giffard MS, questioned the First Minister in the Senedd on Tuesday about the package of improvements once promised by Welsh Labour for Swansea junctions along the M4, which were then cancelled by Labour in 2023.

The much-needed projects, would have seen improvements made at M4 junctions, including 45 (Ynysforgan) and 47 (Penllergaer) – which are grid-locked daily, causing long delays and nightmare journeys for the hundreds of commuters using the M4 every day.

But in an exchange this week in the Senedd, Tom Giffard MS called on the First Minister to look again at the cancellation of the projects; and in turn, the First Minister agreed to ask her Transport Cabinet Secretary, Ken Skates, to look at what could be done.

In a debate in the Senedd, Tom Giffard MS asked the First Minister about the cancelled M4 junction upgrade projects at junction 45 at Ynysforgan and junction 47 at Penllergaer.

Mr Giffard said that “a study in 2017 showed that the M4 could come to a standstill around 30 times in a day, and these junction upgrades were absolutely crucial to ensure that we keep Wales and our M4—our main arterial road—moving.”

He asked the First Minister “can I have an assurance from you that you will look again at these junction upgrade projects around Swansea, to see whether they can be brought back under your leadership?”

Responding, First Minister Eluned Morgan replied that “it is important to make sure we keep the traffic flowing, and that’s why there have been methods to introduce speeding limits, for example, to make sure that the flow just continues, and you don’t get that stop start that annoys us all.”

She added that “In relation to the junction upgrades, I have heard the frustrations for many people in those areas, and I’ll ask the Transport Secretary to look into that.”

Commenting on the exchange, Tom Giffard MS, said: “In true Welsh Labour style, all investment into new roads in Wales were stopped in 2023, unless they moved people away from cars and onto public and active forms of transport.

“This meant that much-needed projects such as junction improvements on key Swansea junctions such as Penllergaer and Ynysforgan were shelved too.

“This news came on the heels of the previous decision by the Welsh Government to cancel the M4 relief road project in Newport too, causing gridlock on Wales’ most valuable road.

“I’m delighted that the First Minister has now confirmed that the Welsh Government will now look again and re-visit these crucial Swansea junction projects, and I’ll be keeping up the pressure to make sure they happen!”
