The first global conference on roads was held in Paris on 11 October 1908. To recall the milestone and underscore how valuable roads are to human progress, there is a private initiative  that commemorates this event annually. There is more to roads than meets the eye, and this date gives us a chance to celebrate the work they do, especially for the benefit of development, innovation and our socio-economic future.

From the times of the Roman Empire, when the legendary “Roman roads” were forged, skilfully paved and strategically built to facilitate the movement of armies and trade, until now, roads have evolved into much more than simple paths. These are the pulsating arteries of our society and our lives, and the central theme in the history of civilisations.

In a world that demands more sustainable practices, our cities and urban environments face disruptive challenges. Therefore, we shouldn’t focus on what roads are, but on what they represent: essential investments to promote economies, reduce costs, improve mobility and protect our planet through innovation and sustainability.

Every kilometre of road is a testament to human determination. Every curve, bridge or tunnel shows us that, even in the most difficult times and situations, we can find a path. Every traffic jam reminds us of the importance of planning and collaboration. And every new road, greener and more intelligent than the one before, shows us that progress and preservation can work as one.

Innovation in the road sector: entrenched and emerging trends

Road engineers play a leading role in the mobility of the future. They’re the ones who solve problems, ensure safety and build the connections of the future. They are called upon to create safe, efficient and sustainable routes that unite communities and cultures, and their passion is to overcome the challenges posed by nature and society.

In a world that seeks a greener and more sustainable future, these engineers have a great chance to improve our connections in a way that’s more sustainable. This is possible through innovation, incorporating new practices, or promoting existing practices, such as:

Improvements in energy efficiency: a paradigmatic case is that of glowing roads, which leverage solar energy to meet their energy needs. They are also useful to overcome low-light conditions and make nighttime driving safer.

Safety improvements: thanks to the innovation produced in other fields of knowledge, there are now sophisticated solutions that improve road safety. For example, smart signalling systems with LED projectors, the application of fluid mechanics to disperse mist on the road or the use of lasers to guide drivers.

Improvements in sustainability: for example, with the application of IoT sensors to facilitate preventive road repairs, with the ensuing savings in time and resources.

Multimodality and integration with other systems: intermodal systems are increasingly important since they combine transport methods, including efficient public transport systems.

Have you ever wondered…? Roads trivia

What is the longest road in the world? The Pan-American Highway, known as the ‘Backbone of the Americas’, extends along 30,000 stunning kilometres, connecting fourteen American nations, from majestic Patagonia to remote Alaska. It is a witness to the union of two continents and an invitation to explore the diversity of our hemisphere.

What road goes around an entire continent? In Australia, Highway 1 boasts an impressive length, at approximately 14,500 kilometres. It’s a circle that surrounds an entire nation and inspires us to believe that there are no limits to what we can achieve.

What motorway in the world has the most lanes? Houston, Texas, USA, is home to the famous Katy Freeway, part of Interstate 10. What’s so surprising about it? Some sections of this motorway have up to 26 lanes! This achievement shows how roads can be true marvels of engineering and symbolises the vastness of our constantly moving world.

What is the “fastest” road? Germany’s autobahn, famous for its sections with no speed limit, spans more than 12,800 kilometres, paying tribute to speed and efficiency. It shows us how human vision has no borders when it comes to connecting distant destinations.

What is the most dangerous road? The “Road of Death” in Bolivia, with its intrepid and narrow mountain paths. Classified as one of the world’s deadliest roads, it shows how determination can open doors even in the most inaccessible mountains.

What is the symbol of adventure and freedom on the road? Historic Route 66 in the United States, which runs over 3,945 kilometres, is symbolic of adventure and freedom. Crossing the country from coast to coast, it shows how human vision has no limits when it comes to exploring and discovering new horizons.

What innovations are being made in road engineering? Many, as we mentioned! In 2020, the Netherlands surprised us with the first glowing road in the world. This innovative system absorbs sunlight during the day and provides up to 8 hours of light in the dark. It’s an example of how technology can illuminate our path towards a more sustainable future.
