Traffic Calming Studies and Reports

Safety: Vision Zero

Portland families deserve safe streets on which to walk, bike, operate mobility devices, access transit, and drive. PBOT aims to make our transportation system the safest possible and to move towards zero traffic-related fatalities and serious injuries in the next 10 years. This effort is known as Vision Zero.

Vision Zero acknowledges that the death or serious injury of even one person on Portland roadways is too many. When answering the question, “How many of our family members, friends, or neighbors can we accept being killed or maimed in traffic?” the only acceptable answer is zero.

The Portland Bureau of Transportation is committed to developing a Vision Zero safety strategy that outlines how street design, traffic enforcement, and education will realize our vision.

A critical component of our effort is reporting on our progress. On this page, you can learn more about our approach to Vision Zero (as laid out in our 2-Year Workplan), examine crash data and trends, learn about our current safety efforts, and view safety education resources.
