Access Management: Synthesis of Practice (2024)

This report includes the findings of an in-depth literature review of technical and local resources from across Canada, a case study review, a series of interviews with agencies and municipalities, and a survey of practitioners. While the foundations of many locally used resources are rooted in the Transportation Association of Canada (TAC) Geometric Design Guide for Canadian Roads (GDG) Chapter 8 principles, adaptations are commonly made to align access management practices to local contexts. While the review confirmed that the guidance in Chapter 8 was generally comprehensive, there were several emerging practices that warrant further consideration in a future update to Chapter 8. These practices include the following topics, discussed in more detail in this report:

  • Intersection functional area (interchanges and roundabouts)
  • Access spacing by classification and context
  • Strategies to reduce or consolidate accesses
  • Multimodal integration
  • Safety evaluation of access management strategies

In addition, the results of the surveys and interviews identified several additional areas of potential updates to Chapter 8, including a number of overlapping areas:

  • Safety considerations
  • Type of context and locational attributes
  • Multimodal integration
  • Operational requirements
  • Navigation
  • Rationale
