Major growth in cities across the world will generate an unprecedented number of urban and road building sites.

This growth leads to environmental, cost control, performance in use and comfort issues. Citizens and local authorities are becoming increasingly demanding in terms of noise standards, pollution and overall control of disruption.

Using a technology based on a network of nanosensors built into the road and innovative algorithms, SMART-R makes roads more intelligent, safer and longer-lasting.

SMART-R aims to be able to offer a range of services for different stakeholders based on a platform that collects data from buried or mobile systems at strategic points along the road.


The SMART-R technology is based on the use of network of nanosensors detecting deformation, arranged in a mat or built into the road itself, to be able to weigh trucks in motion. The information acquired, including strain gauges, temperature, humidity and speed, is processed algorithmically.

All this data provides knowledge about road deformation, reporting precise measurements (max. error 5%) of vehicle weights in motion, even at high speed (80–100 km/h).

The mobile system proposed by SMART-R provides measurements that are currently inaccessible for many construction stakeholders.


Real-time data analysis makes it possible to detect the footprint or weight of a specific vehicle, control traffic management in smart cities, identify areas of infrastructure that need maintenance or quickly detect risky situations (ice, driving in the wrong direction, deviation of an autonomous vehicle).

SMART-R thus fits within the global trends of the city of the future, taking advantage of IoT growth by offering innovative services, particularly in the construction and public works sector.
