This spotlight series is dedicated to showcasing the best practices shared by ERSC members. Each month, we highlight a different member’s innovative road safety initiative. By presenting these success stories, we aim to create a collaborative environment where others can recognise, celebrate, and adopt lessons learned and best practices.
Our October spotlight features the project Plug Smart ® Pro, Smart Road Safety Device led by Metalesa in Valencia, Spain. The project aims to reduce road crashes by developing road safety infrastructure that uses technology and artificial intelligence to detect risks, prevent crashes and protect road users.
Why has this initiative been recognised as Good Practice of the Month
This initiative has been selected because of its innovative approach to tackling one of the leading causes of road fatalities, run-off road crashes. By effectively using technology and artificial intelligence to turn conventional barriers into smart, connected systems, Plug Smart Pro enables real-time risk detection, immediate driver alerts and faster emergency response. Its scalable, universal design and proven public acceptance make it a powerful tool for improving road safety for all users and advancing Europe’s Vision Zero goal of reducing traffic deaths close to zero by 2050.
Key inspiration behind the initiative
The initiative addresses the stagnation of mortality figures in Spain, particularly run-off-road crashes, which remain one of the leading causes of road fatalities. Research shows that traditional measures only mitigate the consequences rather than prevent incidents. By implementing technology, artificial intelligence, and real-time connectivity, the initiative will fill a critical gap in road safety and create smarter, safer roads that protect all users.
How does PlugSmart® Pro work?
The PlugSmart® Pro is a small, modular device, about the size of a brick, that attaches easily to barriers, guardrails, or other roadside structures. Its sensors detect hazards like crashes, icy roads, poor visibility, or pedestrians near the road. The device then flashes warning lights for drivers and alerts authorities in real time.
Project activities
Launched in 2020, the PlugSmart® Pro Project has involved collaboration with technology partners, universities and specialised suppliers. Significant project developments include:
A scientific study on run-off road crashes was conducted with the Universitat de Valencia to identify causes and risk factors.
The development of prototypes (2021) and optimisation of electronics casing, firmware and a management platform (2022-2023).
A world-first pilot at the Bimilenario Bridge in Elche, Spain, turning a conventional barrier into a smart connected parapet.
The evolution into a universal solution (from 2024) adaptable to any road equipment, scalable internationally and powered by renewable energy.
The launch of the first commercial deployments in 2025 including high-risk motorway ramps in Murcia with the Ministry of Transport and Sustainable Mobility, to validate real-world impact and user acceptance.
Outcomes of the initiative
PlugSmart® Pro has demonstrated that smart infrastructure can significantly improve road safety by transforming passive barriers into intelligent connected systems. Scientific studies show that such solutions could prevent nearly 60% of severe or fatal run-off-road crashes. Early pilot tests have already indicated a measurable reduction in vehicle speeds, and the system has also accelerated emergency response times by sending real-time alerts directly to control centres. This initiative has been applauded by the public with 100% of pedestrians and 70% of drivers rating the solution positively. The project has already received awards and recognition in international conferences and upcoming large-scale deployments of the technology will continue to measure its value as a scalable road safety innovation.
