Neighborhood Traffic Calming
Program Overview
The City of Seattle has been working to lower traffic speeds on neighborhood streets since 1978. Since then, we've worked with communities to install thousands of traffic circles, speed humps, and chicanes. We review possible traffic calming locations every year and prioritize streets based on:
- recorded speeds and traffic volumes,
- reported crash history,
- nearby destinations (schools, parks, community centers, libraries, transit stops, etc.),
- the City of Seattle Race and Social Equity Index, and
- street design (missing sidewalks, missing curbs, wide travel lanes, etc.).
If you are interested in a low-cost traffic calming solution for your neighborhood, Parking Management may be an option. If your street only allows parking on one side, allowing parking on both sides of the street can be an effective traffic calming tool. Narrower streets encourage people driving to slow down.
