Traffic Services' goal is to advance projects to improve communities in Washington state. We provide technical assistance to local jurisdictions and link them up with training at the planning, project development, design, construction, maintenance, and operations levels. We also provide federal safety funding to jurisdictions to reduce fatal and serious crashes. Further, we promote and facilitate information sharing between jurisdictions, and serve as a liaison between agencies and governments, citizens, WSDOT, and the Federal Highway Administration.
Here are some examples of how we can help:
- Applying traffic laws and rules
- Use of traffic control devices, including use of the 2009 Manual on Uniform Traffic Control Devices (MUTCD), changes and experimentations for the MUTCD, and WAC 468-95.

- Speed management/traffic calming
- Traffic signals: increasing traffic signal operations and/or visibility (pdf 58 kb) and adaptive signal control technology
- Roundabouts (pdf 142 kb)

- Intersection conflict warning beacons (dynamic intersection or active warning systems) (pdf 55 kb)
