Final evaluation report: Cerema publishes the final assessment of the impact of the measure, 2 years after its implementation.
Cerema, which carries out the evaluation in collaboration with ONISR and Gustave Eiffel University (formerly Ifsttar), monitors the impact of this measure on speeds, accidents, journey times and user perceptions. A socio-economic assessment has also been carried out. Since 1 July 2018, the speed limit on two-way roads outside built-up areas (without central separation) has been 80 km/h.
The Covid-19 pandemic severely disrupted travel in France from March 2020, both in terms of volume and structure, and compromised the collection of speed data for the first half of 2020. This context led to a 20-month assessment of the accident rate, i.e. from July 2018 to February 2020.
