Road Safety and Accident Prevention: 21st Century Infrastructure

Road Safety and Accident Prevention: The Need for Adaptation and Road Safety

For decades, our roads have been the pillars of mobility, connecting cities, towns, and communities. However, as we move towards an increasingly digital and sustainability-oriented future, it becomes evident that our road infrastructure urgently needs an update. While efforts have been made to maintain and repair existing roads, not enough has been done to adapt them to new mobility methods, Smart Cities, and the growing demands of an ever-increasing population.

The need for infrastructure adaptation to cities

The world is changing at a dizzying pace, and our cities must keep up. Cities are evolving into smarter environments where technology plays a fundamental role in traffic management, road safety, and energy efficiency. However, our urban roads remain largely analog in a digital world. An updated road infrastructure is needed that integrates technologies such as smart sensors, traffic management systems, and vehicular communications to improve traffic flow and reduce accidents. Administrations are aware of this issue and have been implementing data-driven strategies for years to improve citizens' lives.

Sustainable mobility

Sustainable mobility is another crucial aspect that our roads must address. With increasing environmental awareness and the need to reduce carbon emissions, it is imperative to promote the use of public transportation, bicycles, and electric vehicles. However, current roads are not designed to accommodate this diversity of mobility options. Safe bike lanes, charging stations for electric vehicles, and infrastructure that fosters efficient public transportation are needed.

Population growth and urbanization are global trends that are putting increasing pressure on our roads. Cities are more populated than ever, meaning more vehicles on the roads and greater infrastructure demands. However, many of our roads were not designed to handle this volume of traffic, resulting in congestion, longer travel times, and increased pollution. It is essential to adapt our roads to meet the needs of 21st-century cities and beyond.

Road safety and accident prevention

One of the most critical aspects when talking about road infrastructure is the safety of its users. Every year, thousands of lives are lost in traffic accidents, and many more people are seriously injured. It is crucial that our roads are designed with a focus on road safety to reduce these tragedies.

Technology plays a fundamental role in accident prevention. Advanced driver assistance systems, such as automatic emergency braking and blind-spot detection, can help avoid collisions before they occur. Additionally, adequate lighting, clear signage, and regular infrastructure maintenance can improve visibility and reduce risks for drivers.

Technologies like PLUG&META® are a clear example of innovation in the field of SMART ROADS and a clear trend that reaffirms the administration's commitment to the new era. The most appropriate decisions for urban mobility must always be based on real data to ensure the safety of all road users.

Road education also plays a crucial role in accident prevention. Awareness programs about the importance of wearing seat belts, respecting speed limits, and avoiding distractions while driving are fundamental to promoting a culture of safety on our roads.

At Metalesa, we firmly believe that accident prevention requires a holistic approach that addresses both technological and human aspects of road safety. By investing in safer infrastructures and promoting responsible behavior from road users, we can work towards drastically reducing the number of accidents and saving lives on our roads.



Collaboration between the private sector and the administration

Addressing these challenges requires close collaboration between the private sector and public administration. Technology companies can bring expertise in innovation and the development of smart solutions, while governments have the power to establish policies and regulations that encourage investment in road infrastructure. It is crucial for both parties to work together to ensure the safety, mobility, and well-being of everyone who depends on our roads.

In summary, our roads need an urgent renovation to adapt to the demands of the modern world. From integrating smart technologies to promoting sustainable mobility and managing urban growth, many aspects must be addressed. Only through effective collaboration between the private sector and public administration can we ensure that our roads are prepared to meet the needs of Smart Roads in the smart cities of the present and future.

Transitions and Terminals: Innovative solutions for black spots

Roads shorten distances and bring people closer together. That’s why it is so important to ensure their safety as much as possible, so that they reach their destination safely, be it their work, their family or their friends. The different national, regional and local administrations keep the main black points of our roads identified and updated, and from Metalesa, we have been participating in a number of projects that aim at providing safe solutions to these specific locations for many years. A clear commitment to remodel our roads includes equipping them with new infrastructures that fulfil the purpose of ensuring road safety. In this scenario is where we act.

Cullera-Favara Section: One of our latest Road Safety projects

During the last two years, work has been done in Cullera on the construction of a section that will undoubtedly represent a milestone for the improvement of the communication routes in the area.

As José Luis Ábalos, Minister of Transport, Mobility and Urban Agenda points out, "this action will translate into an improvement in road safety by creating an alternative route to that of the current national highway as it passes through both towns."

The truth is that residents have been demanding the completion of this infrastructure for a long time, and finally, they will be able to count on the Cullera and Favara bypass, a section included in the A-38 corridor, which represents the largest investment in this matter of infrastructures that the central government has never carried out in the Valencian region of Ribera Baixa.

Metalesa in the project: installation of transitions and terminals

At Metalesa we have been in charge of installing more than 15,000 meters of META16 metal parapet with containment level H3. We invite you to sit down to enjoy this impressive video where you can see the result of so much work.

But the objective of this article is to present the transitions and terminals, other road safety products that are very unusual in Spain, but undoubtedly essential on the roads, and which will become more widespread as soon as our leaders and public administration technicians acquire greater sensitivity for the situations they avoid.

Blackhead removal with transitions and terminals

The black points or accident concentration sections (TCA) are sections of the road network in which a large number of traffic accidents occur each year.

From the Cullera City Council, they affirm that this work "was of vital importance to prevent more people from losing their lives." In addition, Oro Azorín, mayor of Favara, also believes that it will offer the town a great increase in road safety.

Municipal sources in Cullera also assure that it is good news for the entire Valencian Community because the black spots on the roads that have suffered, especially the populations of the coast, are being eliminated.

Transitions for roads

The installation of transitions for roads allows the union between containment systems of different nature, that is, it connects two safety barriers of different cross section or different level of containment, such as a metal parapet and a New Jersey-type concrete barrier.

At Metalesa we have an approved Transition designed in a versatile way, that is, it allows us to connect both our META13, containment level H2, and our META16, containment level H3, to a contiguous concrete barrier.

It is a device designed and manufactured entirely by Metalesa, and approved according to the French standard NF-058, which implies that the transitions that we install have been shock tested on a full scale according to said standard. We are the only Spanish company that has tested transitions between different containment systems on a full scale because we have decided to be ahead of our competition. We believe that the French standard represents the future of what the European standard will establish, which is currently being drafted by the standardizing technical committees to which Metalesa belongs.

What are the advantages of installing a highway transition?

  • System reliability: In the event of a side impact of the vehicle, it behaves like a conventional metallic barrier, thus guaranteeing the containment and adequate redirection of the vehicle.
  • Easy to repair and repair parts available from stock.
  • Anti-corrosion treatment: We offer various finishing options for road transitions, both hot-dip galvanized and thermo-lacquered, as a treatment that combines both processes.

Road Terminals

Highway terminals are placed at the ends of containment systems such as parapets or metal barriers, to ensure greater safety against a frontal impact with said completion. We have a wide range of models with different characteristics and certificates, all of which have been tested by means of tests in an accredited laboratory according to the EN 1317 standard.

We offer supply and installation of three models:

Model T50 - 50KM/H

This terminal is ideal for urban environments, in areas whose maximum permitted speed does not exceed 50 km / h.

Model P2 - 80KM/H

Terminal P2, unlike Model T50, is used on highways, where the permitted speed is not higher than 80Km / H. We have several designs of road terminals.

Model P4 - 110KM/H

This terminal is also designed to be installed on highways, but on high-speed roads. We have several homologated models of anchoring to the ground, both for concrete and earth ground.

Undoubtedly, projects such as the construction of the Cullera-Favara Section, which include infrastructures for road safety such as our transitions and terminals, show that there really is a commitment to make the roads safe roads that serve what we commented at the beginning of this article: bring people closer.

Types and applications of railway equipment

Since our origins at Metalesa we have always been concerned about safety. Whether in urban environments or roads we have always worked to offer the best products with which to keep pedestrians and vehicles safe. But our scope of action does not stop there, we also have extensive experience in railway equipment products, and on this we would like to focus today’s article so that you know a little more about everything we can do for your railway project.

Products and regulations on railway safety

Like any product, there is a railway safety regulation that must be complied. In railway equipment, this corresponds mainly to the infrastructure managers (ADIF in Spain or SNCF in France). At Metalesa we have been working for many years on the deployment of the high-speed rail network in Spain, collaborating with the main companies in the sector and offering products that meet the highest quality standards.

Railings and fences type ADIF

In order to guarantee safety at the crossing points in railway infrastructures operated by ADIF, at Metalesa we have a complete range of specialized security systems that comply with the quality standards set by the network administrator.

With our range of ADIF-type railings and fences we can create a complete protection system for pedestrians on bridges, viaducts or other passage areas within railway infrastructures. When a project of these characteristics is presented to us, we carry out a study of the needs of the layout and manufacture any element that may be required.

Different anticorrosive treatments can be applied to our entire range of railings and fences. Depending on the characteristics of the project and client specifications, we can apply either a hot galvanized finish, or a thermo-lacquered finish or even a mixed application for more aggressive environments.

Railings and handrails for stations

At Metalesa we manufacture railings for stations with various shapes and materials to guarantee the safety of passengers, while adapting the product to the aesthetics of the place. We can manufacture them with various materials. Steel is the usual one, and under client requirement, the product can receive anti-corrosion treatments like hot-dip galvanization or thermo-lacquering to guarantee their resistance to deterioration caused by the weather and time.

We also manufacture stainless steel railings of different quality and with a wide variety of finishes, always adapting to the needs and aesthetics of the railway station.


Fences and station enclosures

Train, subway or tram stations need enclosure and fences systems that are resistant to high volume of traffic while complying with current regulations.

Regarding security systems to offer protection to people in areas close to stations or railway facilities, we have a wide variety of station enclosures and fences that we can manufacture to order to be able to solve and adapt to the requirements of the project.

The enclosure systems for railway stations are products that are often subject to inclement weather. That is why at Metalesa we work to offer different anti-corrosion treatments such as hot galvanizing, thermo-lacquering or a mixed finish that offer a layer of protection against superior humidity and oxidation.



Handrail and grilles for walkways

Another of the safety systems that are installed in railway tunnels are handrails and grilles for walkways. These elements are intended to provide safety for pedestrians inside a tunnel. Our extensive experience in the tunnels of the suburban and high-speed rail network allows us to offer a customized product manufactured according to the materials and criteria that best suit the project.

When facing a new project, our technical office will carry out a needs study and present you with a proposal that meets your needs.

industrie 4.0

Industry 4.0 and road safety

At Metalesa we are well aware of our great responsibility since looking after people security is our goal. Thus we keep a close eye to all technological updates and breakthroughs that may bring benefits to our sector. Industry 4.0 is a wave that need to be taken.

What is industry 4.0?

This concept is not new, and indeed it is becoming global social phenomenon. It refers to the addition of digital technology to all manufacturing processes to an extend that it is considered the fourth industry revolution. Now, a little bit of history.

4.0 industry


By the end of XVIIIth century, steam machine burst meant the beginning of the First Industrial Revolution. No doubt road safety sector faced new challenges with railway mechanization. But lot was lacking yet until today’s situation, this was only the launch of the industrialization.


Second Industrial Revolution started around 1870. New energy sources like gas, petrol and electricity drove a great acceleration in all senses. Furthermore, it opened doors to internationalization.


2006 is commonly considered as the beginning of the third phase of industrial growth. At that time, industry was pushed to the need of more renewable energy sources, which led to the will of directing all efforts to more sustainable objectives. TICs and automation played a key role.


No matter third revolution as starting to be protagonist, it was with fourth revolution when all capabilities started to bring together synergies. It is considered to be started around 2011 and the truth is that since then, technology has been pushing forward industry operations to a new level.

How does Industry 4.0 impacts on road safety?

The technology transformation power is unquestionable. It allows to simplify, accelerate and optimize all industrial processes, that’s why any road safety company that has not embraced yet this digital transformation will be left behind. This is not Metalesa’s case.

Our infrastructures

We have strategically adopted Industry 4.0 in all areas of our business: from employee security to communications or manufacturing digital software .

Bridge barriers and cornices

Contention systems that have been tested with real crash essays. Furthermore, its materials are exposed to anticorrosive treatments.

Regarding cornices, in Metalesa we innovate each day with designs that allow to host either canalizations with water, gas, electricity or telecommunication supplies.

4.0 industry

Noise barriers and panels

We manufacture noise barriers of a number of different materials, from steel, aluminium or methacrylate to fight noise pollution to bird anti-collision, to even some “vegetable” that can be integrated in an environmental friendly way. In Metalesa we provide the most suitable option for any project or need; security, noise isolation and aesthetics can go hand-in-hand.

Handrails and Fences

These handrails can be installed either in railway infrastructures or over bridges and viaducts. Hence, we adapt to any type of structure and with a wide variety of materials. Following high quality standards, our handrails are exposed to anticorrosive treatments with three possible finishes: hot-dip galvanized, thermo-lacquered or both combined at the same time.

Our engineers optimize anchoring systems with breaking-edge calculation technology so that best results are achieved in handrail installation and performance.

Of course, looking after the people in charge of our processes and equipment is one of our priorities. We have always extrapolated our concern for road safety to our people’s security,

Equipment for railway and tunnel infrastructures

Spanish railway network has been counting on Metalesa’s products and experience for a lot of years. We provide wide experience in manufacturing, supplying and installing metallic equipment for overpasses like ADIF and SNCF fences or handrails, fences for train stations or stopping places, protection for electric cables, or combined systems.

4.0 industry

Technology is all around our manufacturing and installing processes, and believe in its advantages. Our vision inspires us to keep on implementing our technological capabilities to be at the front line of industry 4.0. Staying behind is not an option for Metalesa when it comes to innovation.

Should you require our services, don’t hesitate to contact us, all road and urban infrastructures are possible with Metalesa.


METALESA, heading towards international success

On the occasion of the first Opportunities for internationalisation meeting organised by Cajamar and El Mundo, César Valero, Deputy Director at METALESA, gave an interview along with directors from other companies of the Valencian Community. They contributed their outlook and experience on the keys, challenges and risks of internationalisation to a company.

international success - range of acoustic screens

Among other ideas, the experts commented that the circumstances may be more favourable or less so depending on the country in which you want to expand, and that the market and legal contexts should be studied in detail. César Valero stressed the importance of hiring people that enable the organisation to compete in a more demanding environment. He also pointed out that the company’s size is not the only determining factor in internationalisation, but did recognise that in sectors such as public works it is a great help to be more competitive.

The interview highlighted the progressive growth of METALESA in France and its countries of influence, which requires great strides in self-discipline to provide a quality service.

Other topics discussed were the importance of seeking expert advice on the target market, opening up to foreign partners and the financial muscle to undertake a process that may take time to produce results. Read the interesting interview about international success in full.



During Engineering Week of the UPV’s School of Civil Engineering (SICMA 2019), METALESA will hold an event on Tuesday 19 February at 12:15pm to announce the winners of the 2nd  METALESA AWARDS  for the best Final Degree Project.

One year more, this initiative is part of the Metalesa Talent Platform, which arose from our company’s commitment to promoting endeavour and talent amongst new generations of engineers as well as to offer them a real experience of the civil works sector.

The event will be attended by Dr Luis Montoro González, Professor of Road Safety at the University of Valencia and President of the Spanish Road Safety Foundation. His speech will deal with the challenges we are face with when integrating emerging technologies into road safety systems.
