In Dubai, Crosswalk Safety Gets a Ground-Level Upgrade

In the heart of Dubai, where modern architecture meets relentless traffic, pedestrian safety faces unique challenges. Crosswalks must compete for attention in an environment of constant motion, cars, buses, delivery trucks, and the occasional impatient driver rushing to their next destination.

In such a setting, every fraction of a second matters. The clearer the signal, the quicker the driver’s reaction. That is why Dubai turned to SERNIS’ SR-50-RYG, a robust road stud that displays the same red, amber, and green sequence as the traffic lights, but right where drivers are already looking: the road ahead.

From concept to reality in Dubai’s streets
This is not theory. Dubai’s Roads and Transport Authority (RTA) has already installed the SR-50-RYG at multiple pedestrian crossings, embedding the signals directly into the tarmac. Phase Two of the project ended on June and added 10 more crossings, bringing the total to 27 sites now equipped with SR-50-RYG road studs across the emirate.

Mohammed Al Ali, Director of Intelligent Traffic Management Department, RTA, explains:
“The Smart Pedestrian Signals technology is operated by a system reliant on sensors connected to a ground optical system synchronized with the signal’s light operation. It perceives pedestrian movement before and during crossing, significantly enhancing pedestrian safety while boosting traffic efficiency and ensuring better management of signal timing.”
The idea is elegantly simple: when the traffic light turns green, so does the road stud. Amber? The stud mirrors that. Red? The unmistakable glow appears at wheel level, directly in the driver’s path. By reinforcing the message from above with light from below, the crossing becomes harder to miss, harder to misinterpret, and harder to ignore.

Why the SR-50-RYG works where others struggle
The Dubai climate can be merciless. Summer temperatures push the limits of most equipment. Fine dust drifts through every gap. Heavy trucks pound the roads day and night. Any solution that hopes to survive here must be engineered for extremes: and the SR-50-RYG is built exactly for that.
- Its IP68 sealing ensures no dust or water intrusion.
- Stainless steel and polycarbonate construction withstands constant stress.
- With mechanical resistance up to 160 tons, it shrugs off the heaviest vehicles.
- Rising only 4 mm above the surface, it’s safe for all road users and even snowplow-ready for colder climates.
In other words, if it works here, it will work anywhere.

Zero Accidents and Measurable Impact
The results speak for themselves. Al Ali adds:
“The system proved effective in improving pedestrian safety for those who require more time to cross—elderly residents, people of determination, or individuals with luggage or pushchairs. Since the introduction of smart pedestrian signals, no pedestrian accidents have occurred at the equipped crossings. Vehicle flow has also improved, as the system adapts traffic light timing when no pedestrians are detected.”

Beyond the crossing – a vision for safer roads
The SR-50-RYG is more than a piece of hardware. It’s a philosophy of layered safety. Drivers don’t always catch the traffic light in their peripheral vision, especially in poor visibility from rain, dust storms, or low sun glare.
By adding a second, ground-level signal, you increase redundancy. It’s like having a co-pilot in every lane, quietly reminding drivers of the rules at the very moment they matter most.
It’s a small change that can transform driver’s behavior, reduce violations, and give pedestrians a little more peace of mind when stepping onto the road.

Why choose SERNIS for your project
When SERNIS develops a road safety solution, it’s not about quick fixes. It’s about engineering products that last, perform, and adapt to local challenges, whether that’s the heat of Dubai, the snow of Northern Europe, or the heavy rains of Southeast Asia.

From design and manufacturing in Portugal to installation support worldwide, we ensure every SR-50-RYG delivers the same uncompromising quality. And we don’t just sell a product, we work with our partners to tailor each installation to the needs of their roads, traffic patterns, and safety goals.

The future is already here — will your city be next?
In Dubai, drivers are already seeing the difference. Pedestrians are crossing with greater confidence. And the SR-50-RYG quietly does its job, day and night, without fuss.

The question is no longer whether this technology works, it’s whether your city can afford not to have it.
Contact the SERNIS team today at sernis@sernis.com to explore how the SR-50-RYG can be integrated into your crossings. 
The next safer street could be yours.

Why the humble flexible bollard is a real hero in urban safety.
This is a win-win thing.
Cars don’t know it’s rubber, and even if they did, they wouldn’t want to hit it. Drivers see a bollard and instinctively slow down or stop. That’s already one safety victory right there.
But here’s the twist: unlike traditional metal or concrete posts, when someone does bump into it, nothing dramatic happens.
- A pedestrian might bump into it, but with less harm.
- A cyclist doesn’t hurt so badly.
- A scooter rider takes a gentler hit.
- A child doesn’t get severely injured if they bump into it while playing.
- And a blind person doesn’t get hurt — they just keep walking, guided safely by design that respects everyone.

Why They Flex (And Why That Matters)
Here’s a fact many people don’t realize: flexible bollards are not just “soft for fun.” They’re designed to flex under vehicles.
These bollards are commonly used around walking lanes, cycling paths, and pedestrian areas. They stop mindless drivers from entering. In some countries they allow emergency vehicles, garbage trucks, and city service vehicles to drive over them if needed.

Think about it:
A normal bollard would have to be extremely robust to stop a speeding vehicle - even steel ones only give the illusion of safety.
If it’s not flexible, either the bollard gets mowed over, or the whole foundation gets damaged.
If the foundation were built to stop vehicles fully, a single bollard would cost ten times as much.
Flexible bollards hit the sweet spot: they discourage parking, stop unauthorized vehicles, and protect pedestrians, cyclists, and vulnerable road users, without needing constant replacement.

Human-Centered Design
It’s not just about stopping cars. Flexible bollards are designed to minimize injuries:
- Cyclists and scooter riders are much less likely to get hurt.
- Children playing on streets are safer.
- People with visual impairments are less likely to get injured by surprise obstacles.
Traditional rigid bollards on sidewalks can be extremely dangerous, but a flexible bollard is guiding, not punishing. In short: they protect people while still doing their job.

Guiding Without Restricting
Flexible bollards give drivers clear boundaries while letting pedestrians move freely. These bollards focus on controlling vehicles without limiting people.
This approach creates safe, intuitive spaces where people can move freely, and vehicles understand their limits, a careful, human-centered design solution that works for the space. And of course, there are more robust bollards available if additional protection is needed.

SR-CITY-BALI: The Best of Both Worlds
For cities that want the look of traditional steel with the safety of modern materials, SERNIS’ SR-CITY-BALI is the answer.
These bollards look like metal, fitting seamlessly into urban landscapes, but are stronger than typical flexible bollards. When struck, they blend 90° to the ground, minimizing damage to vehicles, pedestrians, and cyclists — and then return upright, ready for continued use.
It reinforces urban separation and pedestrian safety while serving as a cost-effective, low-maintenance alternative to cast iron bollards.
For urban planners and road safety specialists, SR-CITY-BALI delivers the perfect balance of function, protection, and style — a bollard that’s as practical as it is visually integrated.

The Right Place for the Right Bollard
Location matters. Flexible bollards shine when they’re strategically placed:
- Walkways and cycle paths.
- Pedestrian zones, and urban squares.
- On streets where city vehicles occasionally need access.
- Parking lots, protecting sidewalks and ensuring safe traffic flow.
- Anywhere you want to discourage unauthorized parking or unsafe driving.
The goal isn’t to build a fortress. It’s to create streets that are smart, safe, and inclusive.

The Takeaway
Flexible bollards:
- Look firm, act smart, and stay kind.
- Protect humans first, vehicles second.
- Allow authorized vehicles through, stop the rest.
- Reduce maintenance costs compared to rigid solutions.
- Bounce back when hit, literally and figuratively.

Protect pedestrians and cyclists while guiding vehicles safely: let SERNIS flexible bollards bring urban empathy to your streets. Contact us at sernis@sernis.com to learn more.

SERNIS Sustainability: More Than a Feature

At SERNIS, we’ve never treated sustainability as a trend. For us, it’s been a quiet but constant part of how we work — not a separate department, but a mindset that touches every product, every process, every decision.
We know that the people who choose SERNIS don’t just expect innovation. They expect responsibility. So, this month, we’re putting into words what has long been part of our DNA: how we build sustainability into everything we do.

We don’t wait for regulations — we act with intention
Whether we’re producing our road studs, our flexible bollards or other road safety solutions, our approach is the same: design for durability, choose materials with care, and optimize for efficiency. These aren’t just nice-to-haves — they’re choices we’ve made deliberately, over many years, to reduce waste, extend product life, and lower environmental impact.
Here’s what that looks like in practice:

Durable by Design
We build things to last. Not just to resist impact, weather or wear, but to be easily maintained and repaired instead of replaced.
- Our road studs use a modular system — when the electronics need replacement, the entire product doesn’t have to go to waste.
- Our O-Ring sealing system makes maintenance faster, cleaner and safer for road workers — reducing the need for disruptive interventions.
- In every product, we seek out ways to simplify the structure, reduce the number of components and ensure that each one has a purpose.

Materials That Matter
Every choice of material comes with a footprint. That’s why we:
- Prioritize recycled and recyclable plastics, especially in our flexible bollards.
- Use sustainable metals (like stainless steel and certified aluminum) from trusted European suppliers.
- Avoid toxic substances — all our electronics are RoHS compliant, meeting strict limits on hazardous materials.

Energy Efficiency, From Product to Production
- We design our LED-based products to use minimal energy, thanks to efficient power management. But our commitment goes far beyond the products:
- We use solar panels and LED lighting in our factory to significantly cut our electricity consumption.
- We’ve invested in low-consumption production equipment and apply preventive maintenance to keep systems running at peak efficiency.
- Every component is tested before final assembly, reducing rework, energy use and waste.

Minimizing Waste (Especially Electronic Waste)
Electronic waste is one of the most difficult kinds to handle — and one we’re determined to keep to a minimum.
- Our team uses a First-In-First-Out system to avoid obsolete stock and ensure full material use.
- We carry out quarterly loss analysis to track and improve.
- And even when we have small quantities, we send electronic waste to certified recyclers.

Smarter Logistics and Local Sourcing
- We prefer local and Iberian suppliers to cut the emissions of long-distance transport.
- Wherever possible, we use reusable packaging with our partners and optimize every delivery for space and weight.
- We favor rail and sea transport over air when shipping abroad.
- We keep packaging volumes to a minimum — always without compromising product protection.

A Lean Factory Is a Green Factory
We apply Lean Manufacturing principles throughout our operations. That means:
- We only produce what’s needed, when it’s needed — avoiding excess stock and unnecessary production.
- We’ve standardized and streamlined our processes, so each one runs as efficiently as possible.
- And our teams are trained to spot and solve inefficiencies, with continuous improvement at the core of how we work.

More Than a Policy — It’s a Practice
For us, sustainability isn’t a side project. It’s embedded in our engineering, our design decisions, our supply chain and our culture. It’s part of how we innovate, and why our partners trust our products to stand the test of time — technically, economically and environmentally.
We know we’re not perfect, but we believe that responsibility is built step by step, and we’re committed to improving every day.

If you're working with SERNIS — or considering it — know that sustainability isn't an afterthought here. It's part of every product we make, and every decision we take.

Mitigating Distraction-Related Risks in Urban Mobility: The Role of Smart Crosswalk Systems

As urban mobility infrastructures evolve to accommodate emerging transportation paradigms, the issue of inattentional blindness—whether in drivers or pedestrians—has become a critical road safety challenge. Despite advancements in vehicle safety systems, NHTSA data reveals that pedestrian fatalities now account for 17% of all traffic deaths, a 20-year high largely attributable to cognitive distraction from mobile devices.

The Neuroscience of Distraction: Quantifying the Risk
Research demonstrates alarming trends:

Driver Distraction:
- 5-second blind spots: Reading a text at 55 mph = driving a full football field without looking (NHTSA).
- Cognitive overload: Texting degrades reaction times 2x worse than drunk driving (Virginia Tech Transportation Institute).

Pedestrian Dangers:
- 1 in 3 pedestrians at risky intersections are texting or talking (Seattle DOT, 2012).
- 2 million annual injuries result from distracted walking (Ohio State University study).
- 38% slower hazard detection when using headphones (Journal of Safety Research, 2021).

Emerging Threats:
- Autonomous vehicles struggle to recognize distracted pedestrians (University of British Columbia study).
- 7-meter longer stopping distances at 50 km/h due to delayed reactions (TRB, 2023).

Solar Road Studs are an Energy-Efficient Road Safety Solution

Solar Road Studs, also known as solar road markers, are solar-powered road safety warning lights that are often placed on the road surface.
Solar Road Studs are low-maintenance solar cell-powered LED illumination devices that delineate road borders and centerlines. They provide drivers with a longer reaction window since they are embedded in the road surface.
The primary function of these lights is to indicate the direction of the road, particularly in challenging rainy or foggy circumstances, as well as to encourage drivers to pay attention to the driving path ahead. Solar road studs significantly increase road safety and minimize the incidence of traffic accidents.
Solar Road Studs are specifically developed to mark crosswalks, roundabouts, and traffic islands, among other things.
You can explore SERNIS Solar Road Studs Range here.

Innovative Solar Road Studs
SR-i19 and SR-i25 are two new solar road studs that use microcontroller technology, have a low profile raising from the surface (9 and 10mm respectively), and are ideal for road delineation, bends/curves, and crosswalks among other applications. 
SR-i19 cutting-edge design gives it greater lighting power (higher light output due to its 3 LEDs for each side) and makes it more resistant (the aluminum base gives it strong mechanical resistance).
The innovative solar road stud SR-i25  has a stainless-steel cap that makes it ready for snowplow machines. The GPS technology built-in allows flashing synchronization. It has high mechanical resistance and a high-performance photovoltaic solar module. 

Solar energy powers road studs, which light up automatically at night 
SERNIS solar road studs are made of an active illumination LED light source and can operate independently for several years. They have a high level of durability, which removes the need for costly cabling installation.
LEDs are much brighter than standard reflective road studs and provide 1km visibility. Solar energy powers the road studs, which light up automatically at night. During daylight hours, the solar cells charge batteries or capacitors, and the LEDs are switched off.
Solar energy sources, as the name indicates, generate ecologically friendly power from sunlight.

Easy to install and maintain
Solar Road Studs require no need for wiring and can be installed anywhere, no matter how remote the location is or how far the location is from the grid. All that is required is to install these lights on the roads and let them be there for years to come since they would not require frequent maintenance.
These intelligent Solar Road Studs operate independently in the open air and they have their own power supply (solar cell), the electrical wiring is eliminated, resulting in a quick and convenient installation.
These features make the Solar Road Studs highly energy-efficient, environment-friendly, and easy to install and maintain.   

Particular applications
SERNIS' innovative design and technology make some of our Solar Road Studs (SR-i25 and SR-i40) snow plough resistant and boost road safety for many years.


Solar road studs are a novel approach primarily intended to improve traffic safety. These lighting products, however, may also be utilized in various applications, such as bike lanes and square and park landscape illumination.
Aside from energy savings, Solar Road Studs improve driver visibility and are a step toward the finest traffic management system.

Sleep Mode
After 24 hours without being activated, SERNIS Solar Road Studs go into Sleep Mode. This means that they can be stored for long periods of time without reaching critically low levels of power.  
The Solar Road Studs are loaded to the maximum level when leaving the factory and - activate the Sleep Mode after 24 hours without use - it can preserve the energy without damage.

i-Stud evolution technology 
i-stud evolution technology applied to some of SERNIS Solar Road Studs increases the performance of solar power studs with energy storage by battery or capacitor. The main advantage of i-stud evolution is the use of microcontroller technology inside each stud, which allows several beneficial features and control options.

KEY Features
Wake Up/Sleep Function
Allows the stud to stay in "sleep" mode before the application, extending the autonomy of the battery

Automatic Brightness Control
Manages the energy stored, adapt the brightness, and regulates the light level in accordance with the energy-charged during the day

Definition of the Working Period
Set up the number of hours the i-stud should work after night detection (when roads studs do not have to operate all night long)

Operation Mode Flash/Steady
Switch the stud’s mode from ‘flashing’ to ‘steady’ and vice versa after installation

Flash Rate
Adaptation of the flash rate after the installation

Night Level Detection
Adjustment of the lighting level detection (Lux) 

Operation Mode Uni or Bi-directional 
Modify the light direction temporarily or permanently

Low Temperature
Detects the possibility of ice forming on roads and changes the LEDs color to warn drivers about the dangerous weather condition (option available)
	
Log File
If a problem with the stud is detected the unit is able to make an internal log to discover what are the causes of the problem

Advantages of Solar Road Studs
