Traffic & safety services

We provide technical assistance and training to local jurisdictions to increase the safety and mobility of multimodal roadway users. We promote and facilitate information sharing between jurisdictions and serve as a liaison between them, and we also provide project development support.

Technical assistance

Providing technical assistance, and connecting local jurisdictions with other WSDOT offices and the Federal Highway Administration to provide technical assistance. Here are some example topics:

  • Applying traffic laws, rules, and design standards.
  • Using traffic control devices, including:
    - The 2009 Manual on Uniform Traffic Control Devices (MUTCD), which provides national standards and best practices for the use of traffic control devices.
    - WAC 468-95, which modifies the MUTCD for Washington state's circumstances and must be used with the MUTCD.
    - Interim Approvals and Experimentations for the MUTCD
  • Helping apply tools to manage motor vehicle speed and access, including traffic calming, road diets, and complete streets.
  • Access Management
  • High friction surface treatments
  • Nighttime visibility (traffic signs, pavement markings, and roadway lighting)
  • Traffic analysis
  • Traffic signals: improving traffic signal operations and/or visibility
  • Roundabouts/Compact Roundabouts
  • Shoulder treatments such as rumble strips and Safety Edge
  • Work zone safety and mobility
  • Helping develop projects for Federal Highway Administration's Accelerated Innovation Deployment (AID) Demonstration Program funding.

Project development

Providing technical and project development support for federal Highway Safety Improvement Program (HSIP) funding, which includes the City Safety, County Safety, and Railway-Highway Crossings Programs.

Helping reduce crashes, including fatal and serious injury crashes by:

  • Crash data analysis including GIS and crash tree analysis.
  • Developing or updating local road safety plans.
  • Conducting operational reviews of roads and streets and developing solutions that have the potential to reduce crashes.

Traffic analysis
