My research focuses on data-driven monitoring of tire–road friction using Connected Vehicle (CV) data, also referred to as Floating Car Data (FCD). By combining experimental mechanics with advanced data analysis, I develop models for validation and follow-up of tire–road friction. The aim is to improve traffic safety, particularly under Nordic winter conditions, and to increase the efficiency of winter road maintenance by utilizing data from connected vehicles.

I previously contributed to the Digital Vinter project, which aimed to enhance winter road maintenance using connected vehicle data, in collaboration with the Swedish Transport Administration (Trafikverket) and data providers. Since the completion of Digital Vinter, I have continued to work closely with Trafikverket on research that supports the digitalization of winter road management.

In 2024, I organized and was responsible for a measurement campaign in Kiruna, Sweden, where we evaluated two suppliers of connected vehicle data for the follow-up of tire–road friction. The campaign was a success, and the results demonstrated good correspondence between the two data sources as well as with conventional measurement methods (ViaFriction and Coralba).
