Vision Zero Arterial Traffic Calming Project

Project Overview

Keep an eye out for changes coming in fall 2024 across the City of Seattle. This Arterial Traffic Calming program is part of Vision Zero at the Seattle Department of Transportation (SDOT). We work on projects that help people travel at safer speeds. Street design interventions to help us reach safe speeds is one of the core elements of our Vision Zero Safe System Approach. 

The safety projects vary from location to location. They may include: 

• Speed cushions
• “No turn on red” signs 
• Marked crosswalks
• New stop signs
• Daylighting projects - This means adding parking restrictions at intersections to improve visibility of people crossing the street. 

We identified 10 arterial corridors for priority traffic calming using: 

• Our High Injury Network, the city streets with a history of serious injury and fatal crashes
• The City’s Race and Social Equity Composite Index, a tool based on census data that helps us know where underserved communities live
• Data about high rates of speeding around the city

A 2024 project in NW Seattle shows many traffic calming improvements at an intersection. This also shows an example of daylighting, which restricts parking near the crosswalk for better visibility.
