A shift is underway in urban roadway design—one that prioritizes safety, livability, and human-centered engineering. Design and Operation of Lower-Speed Collector and Arterial Roads: Synthesis of Practice equips Canadian transportation professionals with practical guidance for designing self-enforcing roads that support lower operating speeds (30–40 km/h).
Drawing on the Safe Systems Approach, the report explores how speed influences collision severity and outlines strategies to align design speed with posted speed on collector and arterial roads. It features ten detailed case study examples, and presents a comprehensive toolkit of speed management measures—from corridor design and intersection treatments to enforcement and pavement markings.
Intended for engineers, planners, and policy makers, this resource bridges the gap between Vision Zero principles and real-world implementation. It also informs future updates to the Geometric Design Guide for Canadian Roads, integrating human factors into every aspect of design.
