Chapter 8 – Access of TAC’s Geometric Design Guide for Canadian Roads (GDG) provides a framework for the review and approval of access proposals, with the goal of ensuring safe and effective vehicle access. Chapter 8 was not updated with other GDG chapters in 2017, and needs to be rewritten. The Geometric Design Committee’s Access Management Working Group has concluded that a full literature review and synthesis of provincial and municipal practice are not feasible to conduct as a volunteer project.


This project will synthesize current access management practices for all roadway classifications across Canada, and will provide the technical basis for a subsequent project to create a new GDG Chapter 8. It will consider technical issues including:

  • Geometric requirements
  • Safety considerations
  • Locational attributes such as land use type and roadway classification
  • Utility and street furniture impacts
  • Application of guidelines

Major tasks will include:

  • A review of the literature and existing access standards (e.g. TAC, non-TAC, FHWA, provincial, municipal)
  • Areview of available access management case studies
  • Preparation of a summary report including recommended best practices for consideration in subsequent work
