Abstract

The purpose of this guide is to provide designers with the basic information necessary to implement a roundabout in a community. It contains the essential principles for the needs analysis, geometric design and planning of a roundabout, particularly regarding traffic control devices, lighting and the environment.

Its content has been taken from foreign reference works and adapted to Québec realities by a team of MTQ road design and safety professionals. Each chapter deals with a specific topic. It is recommended that the basic principles described in this document be applied at each stage of development of a roundabout.

This first edition of the guide will be improved and updated in a few years based on the experience acquired and the comments received.
