Founded by Cécile Villette, Bérengère Lebental and Rihab Jerbi, in 2017, our vocation is to improve the sustainability and the security of road infrastructures.


For this, the team has developed, in partnership with a research team from the Polytechnique School, at the CNRS and the Gustave Eiffel University (ex-IFSTTAR), a learning machine platform and a network of sensors capable of collecting a whole range of data which are analyzed in real-time by internally developed algorithms. This data is sufficiently precise to identify :


  • the type of vehicle entering the TopTrack system while in motion
  • its wheel and axle configuration
  • its weight
  • its speed

These elements are linked to multiple meteorologic indicators and are available on the online platform in real time.
