Catalogue of road types for development of the national road network

L'objectif des documents et publications traduits est de transmettre aux lecteurs non francophones le savoir-faire français exposé dans la publication originale, qu'il s'agisse de méthodologies, d'outils ou de bonnes pratiques. Les publications originales en français sont soumises à un processus de vérification, qui aboutit à un engagement du Cerema sur leur contenu. Les versions anglaises ne sont pas soumises au même processus et ne font donc pas l'objet d'un engagement du Cerema. En cas de différences entre le texte anglais et le texte français original, le texte français sert de référence. Road types are defined in response to the need to develop France’s national road network in a coherent way, and to have road characteristics that are readable by users and that offer a good level of safety. This document constitutes the new Catalogue of Road Types for Development of the National Road Network. For each of the eight road types, it offers a description sheet giving details of the uses, the technical characteristics and the expected performances / impacts. It also proposes a method to help select a road type, for use during road suitability studies. This work is intended for project owners of a variety of types of road project: development of existing roadways (localised or extensive roadwork) or creating new infrastructure. It has “instruction” status for the national road network, as conferred by the technical report of 1 October 2018. It can be used by the local authorities for developing projects on their own structural network.
