Covering 2% of the national territory, Île-de-France accounts for 18% of the French population, 22% of jobs and 32% of French GDP. In this respect, the operation and maintenance of Île-de-France’s road network often fail to live up to its strategic nature, its level of use and the challenges it faces, which consist of: on the one hand, properly maintaining and managing an ageing network, to enable it to continue to ensure that traffic flows as smoothly and safely as possible; on the other hand, modernising it to adapt it to the requirements of the ecological transition, in particular by encouraging a diversification of its uses and better links with public transport. These issues are all the more important as they relate to a policy that represents, in Île-de-France (for the State, the departments and the City of Paris alone), an annual public expenditure of around €1.17 billion. The Court's report is limited to national roads, the Paris ring road and departmental roads, and excludes municipal roads that serve homes.
