Brief Summary

On the first July 2018, the French government lowered the maximum authorized speeds on two-way roads without a central separator from 90 km/h to 80 km/h. The network concerned represents approximately 400 000 km of roads outside the built-up area, accounting for 55% of road deaths. The objective of the measure is to reduce the number of deaths on the roads concerned by encouraging the reduction of the average speed practiced by drivers. The analysis deals with a comparison of the number of killed persons on the network concerned, before and after the reduction of the speed limits. The "before" period is 2015-2017. The "after" period is from July 2018 to June 2019. The data used are extracted from the national bodily injury accident file (BAAC). The police fills this file for each road accidents occurring on a road open to public traffic and causing at least one victim (i.e., one user requiring medical care and involving at least one vehicle).

Outcome Measures

Primary Outcomes (1)

• Evolution of the number of fatalities in road accidents before and after the implementation of the measure

  the number of fatalities in road accidents on non-motorway non-urban roads during the period July 2018-June 2019 ("after" the measure) compared to the number of fatalities during the period 2015-2017 ("before" the measure)

  before period: 2015-2017 / after period: July 2018- June 2019

Secondary Outcomes (1)

• Sub-groups analysis of road fatalities, by type of road users, before and after the implementation of the measure

  before period: 2015-2017 / after period: July 2018- June 2019

Study Arms (1)
