Roads remain one the most dangerous infrastructures, with around 1.19 million people losing their lives in road traffic accidents each year.
Using AI and satellite technology we are able to predict, prevent, mitigate and manage road traffic risks before they escalate.
Harnessing the power of AI-driven insights, we can make our roads more efficient and save lives.

Road accidents claim around 1.19 million lives annually, according to the World Health Organization, despite huge technological advances in both automotive and road safety. The urgency for innovative solutions has never been greater. In response initiatives like Vision Zero are aiming to eliminate road traffic related deaths around the world.

While traditional road safety measures such as traffic signals (even the intelligent variety) have played their part in the global safety efforts, they are no longer enough. Enter satellite-based road safety technology – a game-changing approach that is reshaping how we monitor, manage, and mitigate road risks, keeping a watchful eye on traffic and incidents from 2000km above us in medium Earth orbit.

Have you read?

With the recent advent of AI-powered traffic management and incident detection platforms, there has been a rich seam of innovative developments that are playing a significant role in reducing the numbers of killed and seriously injured on our road networks. But now traffic safety is being elevated to new heights – quite literally. Some experts believe this is the biggest improvement in road safety since the invention of the seatbelt.

The evolution of road safety technology

For decades, road safety relied on reactive measures: analyzing accident-prone areas, deploying police patrols, and using CCTV surveillance. But these approaches have limitations – they depend on ground-level infrastructure, can’t provide real-time oversight everywhere, and often only offer insights after an accident has occurred.

Satellite technology changes the equation. By leveraging geospatial data, advanced imaging, and real-time connectivity, we can now take a proactive approach to road safety. Instead of waiting for accidents to happen, we can predict, prevent, mitigate and manage risks more effectively than ever before.

The European Space Agency’s Business Applications and Space Solutions (BASS) Programme is exploring the possibilities of using space technologies. Advanced road traffic management solutions company Valerann will support the development of an AI and satellite data-enabled traffic monitoring and incident detection platform, designed to enhance nationwide road network safety and efficiency.

The initiative aligns with the BASS programme’s objective of supporting the creation of innovative services that leverage space technology and data in key markets, such as transportation. It is also aligned with the EU Global Gateway Strategy’s aims for seamless, sustainable, and environmentally friendly international corridor management.

This new transformational offering will feature crucial capabilities for managing national-scale road networks. These include superior holistic coverage of traffic and road assets monitoring, risk management and improvement of incident management and prioritization, whilst extending real-time traffic monitoring capabilities to underserved rural roads that often lack advanced monitoring systems. In 2019, 931 people were killed on Britain’s rural road network, compared to 100 on the motorways, highlighting the need to focus on different road categories.

Investing in real-time traffic monitoring for rural areas and for motorways is equally important as it can significantly improve safety, efficiency, and emergency response times. Satellite positioning information derived from mobile and vehicle navigation applications will play a key role in enabling these capabilities.

How satellites are making roads safer

Real-time traffic monitoring and hazard detection: High-resolution satellite imagery, combined with AI-powered analytics, can detect congestion patterns, monitor accident hotspots, and identify road hazards such as landslides, floods, or damaged infrastructure. Governments and traffic management centres can use this data to issue early warnings, adjust traffic flows, and prevent potential disasters before they unfold.
Enhanced navigation and driver assistance: GPS technology has already revolutionized navigation but now, with advancements in satellite connectivity, we’re entering a new era of vehicle safety. Precise lane guidance, real-time hazard alerts, and dynamic route adjustments are all possible thanks to satellites, reducing the chances of human error – a leading cause of accidents.
Improved emergency response: In an accident, every second counts. Satellite technology enables emergency responders to pinpoint accident locations with extreme accuracy, even in remote areas. With integrated vehicle telematics, automatic distress signals can be sent to emergency services, ensuring quicker response times and potentially saving lives.
Smart infrastructure and predictive maintenance: Many road accidents are caused by poor infrastructure, such as potholes or badly designed intersections. Satellites can provide continuous monitoring of roads, detecting wear and tear long before it becomes a critical safety issue. This allows for predictive maintenance, reducing risks and optimizing government spending on repairs.
Autonomous vehicles and the road to zero fatalities: The future of road safety is autonomous. Self-driving cars rely heavily on satellite data for precise positioning, real-time updates, and seamless communication with smart infrastructure. As these technologies advance, we move closer to a world where human error – responsible for 94% of crashes – is eliminated, and road fatalities become a thing of the past.

Overcoming challenges and embracing the future

Satellite-based road safety isn’t without its challenges. Data security, privacy concerns and the need for widespread adoption are valid issues that must be addressed. However, the benefits far outweigh the potential hurdles.

Governments, technology providers and transportation agencies (be they surface or space-focused) must collaborate in order to harness the full potential of satellite-based road safety. Investments in geospatial analytics, real-time connectivity, and AI-driven decision-making will pave the way for smarter, safer roads worldwide.

Road safety is no longer just about timely warnings on variable message signs – it’s about leveraging the power of space technology to protect lives on Earth. Satellite technology is set to be the ultimate guardian of our roads, providing real-time intelligence, predictive insights, and life-saving innovations.

The question is no longer if we should embrace satellite-based road safety technology, but how quickly we can scale it to save lives. The future of transportation depends on it.
