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
