PTM-AMSP-E

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
