GDG Chapter 11 – Special Roads provides design guidance for special roads such as low-volume rural roads, resource roads, recreational roads, and winter roads.
TAC’s Geometric Design Guide for Canadian Roads (GDG) is a fundamental reference document for roadway design practitioners in Canada. It contributes to the development of regional, provincial and national road and highway systems by helping planners and designers meet the needs of road users with safety and consistency while addressing the context of local conditions and environments. The GDG addresses freeways, arterials, collectors and local roads in both urban and rural contexts, as well as special roads and facilities for walking and cycling.
The 11 chapters in the Geometric Design Guide for Canadian Roads are: 1 – Design Philosophy; 2 – Design Controls, Classification and Consistency; 3 – Alignment and Lane Configuration; 4 – Cross Section Elements; 5 – Bicycle Integrated Design; 6 – Pedestrian Integrated Design; 7 – Roadside Design; 8 – Access; 9 – Intersections; 10 – Interchanges; and 11 – Special Roads (added in 2020).
The GDG is complemented by the Canadian Roundabout Design Guide →
