Neighborhood Traffic Operations

Neighborhood Traffic Operations (NTO) helps ensure safe traffic operations on Seattle’s neighborhood streets. We respond to resident’s questions and concerns regarding speeding, traffic safety, traffic signs, and similar issues. We also administer the city’s neighborhood traffic circle program, and the arterial and non-arterial traffic calming programs.

Answers to common inquiries about traffic on neighborhood streets, such as questions about stop signs, speeding, and how to negotiate a traffic circle, can be found in our Frequently Asked Questions. The FAQ also contains information about traffic laws, parking, pedestrian and bicycle issues, and other traffic and transportation topics.

SDOT receives many requests for new neighborhood traffic circles each year. These traffic control devices are effective at reducing traffic speeds at intersections, as well as the number and severity of collisions. Especially when installed in a series, traffic circles also provide an overall traffic calming effect along the entire street corridor. SDOT funds and installs about 10 to 15 new traffic circles each year. More information is available on our Traffic Circle Program page.

Addressing traffic speeds on our neighborhood streets requires active participation by residents, working in a strong partnership with SDOT. The strategies focus on educating the drivers, whether they live in your neighborhood or elsewhere, to travel on your street in a safe and respectful manner. As we work together in this partnership, we might find that there are relatively simple strategies, such as reconfiguring parking on your street, which might be beneficial. In some cases, more elaborate measures, such as the installation of traffic calming devices, may be appropriate. If you would like to work with SDOT to address speeding on your street, please visit our Traffic Calming Program page to find out more information.

We can also work with you to address speeding on arterial streets, please visit our Arterial Traffic Calming Program page to find out more information.
