Protected Intersection Design Guide

Protected Intersection Design Guide

On September 28, 2021, City of Ottawa staff approved the Protected Intersection Design Guide [ 12.1 MB ] technical guidance document under delegated authority. The purpose of this document is to provide guidance on the design of protected intersections within the City of Ottawa. The Guide aligns with current legislation, regulations, and high-level policies, and builds upon pre-existing protected intersection guidance included in various national, provincial, and City documents. The Protected Intersection Design Guide provides a design process framework for developing protected intersections, and includes the following:

  • guiding principles to inform priorities for designing protected intersections;
  • identification of design requirements, context, and constraints;
  • descriptions of various protected corner types and the process for selecting the most suitable type to be used on each corner of an intersection;
  • functional design elements that are present at protected corners, explaining the intent, target dimensions, and considerations for each element;
  • detailed design elements, including materials and construction; and,
  • signal and lane arrangement measures that can assist in achieving the benefits of protected intersections

The Guide includes a focus on accessibility considerations and elements throughout the design process. This includes new guidance on straight path of travel, delineation between cycle tracks and sidewalks, and the provision of directional tactile walking surface indicators (TWSIs) at protected intersections.
