Why we conduct research
Research impacts all aspects of work at WSDOT, from road materials to the natural environment. We conduct research and development projects to understand why problems occur and how to prevent or correct them through improved information, technology or processes. We use systematic inquiry to improve our ability to deliver transportation projects and operate a safe and efficient transportation system.

Read published research reports that describe the results of our research projects. You can search and browse reports in the Washington State Library catalog. Catalog records include abstracts and full text reports.
Searching reports in the library catalog
- To find a specific report, use a keyword search (i.e. "WA-RD 256.1") or access the associated drop-down menu to search by author or title.
- To search by subject, use the advanced search with "WA-RD*" entered in the first Search Words box. Enter a subject term (i.e. ferries) in the second Search Words box with Subject selected from the Search Type drop-down menu.
- To browse reports, view a list of WA-RD reports by number and use the Previous button to navigate to older reports.
Our bi-monthly webinars showcase WSDOT's research projects. Since 2017, our series has covered a wide range of transportation research topics from engineering to the environment, construction to maintenance, and policy to pica conservation. Recordings of past webinars are available for viewing.

Slow down – lives are on the line.
In 2022, speeding continued to be a top reason for work zone crashes.
Even one life lost is too many.
Each year about 670 people are killed nationally in highway work zones. In 2022, Washington had six fatal work zone crashes on state roads.
It's in EVERYONE’S best interest.
95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
