Leading Roadway Design in Canada with New Industry Guide


After more than three years of work, the Transportation Association of Canada (TAC) has recently announced the launch of the 2017 Geometric Design Guide for Canadian Roads (GDG).

The GDG 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. In the 18 years since TAC published the previous edition of GDG, many aspects of roadway geometric design had changed; and designers were faced with increased constraints, the need to accommodate active transportation, and demands for the development of context-sensitive design solutions.

To address these challenges, TAC commissioned WSP Canada to update this national geometric design guide. As part of this update, the focus was on five prioritized chapters: Roadside Design, Intersection Design, Bicycle Integrated Design, Pedestrian Integrated Design, and Human Factors.

WSP is the primary author of the 2017 edition of GDG. The project team was led by Thornhill-based transportation vice president Michael Chiu with expert technical lead by national road safety manager Geoff Millen and support by senior planner Jeff Ward, who both work in Halifax. The technical team included nationally recognized experts in their respective transportation fields. On behalf of TAC, WSP will be conducting a coast-to-coast seminar program to educate government clients and other practitioners about the new GDG.

The completion of this project and the upcoming seminars highlight WSP’s commitment to knowledge transfer and the company’s dedication to improving roadway design and the national design guidelines.
