City of Ottawa Protected Intersection Design Guide

Throughout the last decade, planners and engineers have been applying the Dutch intersection design principles in the North American context, with the goal of improving safety for all users and improving the accommodation of separated cycling facilities through intersections. The common label for these intersections in North America is “protected intersections”. The City of Ottawa has generally embraced the concept of the protected intersection and has constructed several of them throughout the city. However, practitioners have historically lacked clear design guidance on how to implement protected intersections under various contexts, which can result in inconsistent designs, additional design time and design cost per intersection, and frequent re-designs to accommodate utilities, traffic signaling infrastructure, accessibility, and other requirements.

Alta’s Protected Intersection Design Guide provides a more in-depth exploration of the topic and is intended to serve as a design tool for practitioners working within the City of Ottawa.
