Guidance for posted speed limit reductions in support of vision zero
Lowering posted speed limits can improve safety, but the greatest impact comes when reduced limits are paired with roadway design changes, enforcement, and data-driven monitoring.
Overview
Does lowering posted speed limits save lives? Do drivers actually slow down, and does it make our roads safer?
SMATS Traffic Solutions and the Traffic Injury Research Foundation (TIRF) partnered on a national study exploring how posted speed limit reductions affect driver behaviour on municipal roads. The research digs into the conditions under which lower speed limits deliver real safety benefits.Inside this report:
- How the study was designed and what data was used
- What the data reveals about the real-world impact of speed limit reductions
- Regression and crash prediction models built from connected vehicle data
- A practical decision-making framework for municipalities
- Recommendations for stronger Vision Zero outcomes
This research was made possible through the generous support of Transport Canada through the Enhanced Road Safety Transfer Payment Program (ERSTPP)Access the joint report by completing the form.Note: You are not required to agree to receive other communications from SMATS Traffic Solutions in order to download the report
