PTM-GEODES3-E

The Geometric Design Guide for Canadian Roads is a fundamental reference document for roadway design practitioners in Canada. It contributes to the consistent and safe development and expansion of regional, provincial, and national roadway and highway systems in Canada.

The 2017 Guide contains the current design and human factors research and practices for roadway geometric design. Updates to technical content in chapters 2, 5, 7, 9 and 10 will be included as of August 19, 2019.  Summary of Revisions

The Guide provides guidance in developing design solutions that meet the needs of a range of users while addressing the context of local conditions and environments. Design guidelines for freeways, arterials, collectors, and local roads, in both urban and rural locations, are included as well as guidance for integrated bicycle and pedestrian design.

Chapter 3 – Alignment and Lane Configuration focuses on the design procedures and domains dealing with horizontal alignment, vertical alignment, the coordination of these two critical design elements, and a number of directly related issues including cross-slopes, lane widening, lane balance and continuity, and the use of specialized traffic lanes. Each major section in this chapter generally consists of the following elements:

• discussion of the theoretical and/or empirical basis for the topic;
• a review of design considerations, and where applicable, discussion of the appropriate design domain;
• worked examples as appropriate; and
• cross references to other relevant topics in this Guide, as well as key external references offering additional guidance to designers.
