The typology of accidents is specific to each territory. The particularities of injury accidents are explained by different mobility in rural or urban areas (greater car use in the countryside than in cities, bicycles more present in the city...), meteorology varying from one region to another, different behaviour according to location, etc.
In this chapter, you will discover the analyses of accidentality and the specificities of each territory: rural territories, urban and peri-urban territories, as well as overseas territories. A common indicator for comparing accidentality by territory (comparisons of counties, regions or even countries) is the number of people killed in relation to the number of inhabitants. Variations in mortality per million inhabitants between regions are lower than between counties, with the number of people killed per region being higher than per county, and therefore less subject to statistical hazards or extreme values.
Between 2015 and 2019, road mortality as a percentage of the population in France mainland was 52, close to the European average. In the regions, mortality per million inhabitants per year varies from 25 for Île-de-France to 93 for Corsica. 4 out of 13 regions have a rate below the national average of 52, all in the northern half. In counties, the number of people killed per million inhabitants per year varies from 17 for the Hauts-de-Seine and Paris to 138 for the Alpes-de-Haute-Provence. 24 counties are below the national average, mainly highly populated counties with a strong urban component.
The nature and length of the road network varies greatly from one county to another. The length varies from less than 3,000 km for Paris, the inner suburbs (Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne) and the Territory of Belfort, to more than 20,000 km for Gironde, Puy-de-Dôme and Côtes-d'Armor. While the proportions of motorways and trunk roads vary little (between 0% and 3% each), the same cannot be said for the proportions of county council roads and municipal roads, particularly in relation to the presence of large urban areas:
⦁ county council roads (excluding Paris): 14% (in Seine-Saint-Denis) to 64% (in Aube);
⦁ municipal roads (excluding Paris, of which only 1 km out of 1,626 is not on a municipal road): 34% (in Aube) to 84% (in Seine-Saint-Denis).
The average annual number of people killed per 10,000 km of road over the 2013-2015 period ranges from 6 for Creuse to more than 100 for the counties of the inner suburbs, Bouches-du-Rhône and Paris (236).
