CDVIA is a French traffic engineering consulting firm which specializes in counting, analyzing and modeling transport, traffic and accessibility issues. 


Since 1984, Le Cabinet Isbérie has continually evolved and developed its expertise to become CDVIA (Conseils en Déplacements sur Voirie – Isbérie et Associés) in 1998 which gathers almost 30 employees today. The company is entirely co-owned by 5 employees and Mr Isbérie, ensuring its total independence.


We aim at assisting local authorities, governmental agencies, prime contractors (MOE) and contracting authorities (MOA), civil engineering firms, as well as urban planners in order to assess the impact of their projects, to design solutions and functional policies for a sustainable planning.
