How you can use this data:
These dashboards make collision reports and traffic counts easy to visualize, so you can explore transportation trends and challenges. Analyze overall traffic volume, directions, daily patterns, and crash data.
This data is also used by our citywide transportation plans and in our Vision Zero work. Use it to track our progress and hold us accountable.
- While data is added on an ongoing basis, please allow up to a year for all available data to populate in the dashboards.
- You can also work with this data directly in the City's Open Data Portal.
How we use this data:
This is the data we collect and use to design projects that improve safety, support planning, and advance equity by addressing the needs of each neighborhood:
- Crash Analysis: An inventory of all collision records from the Seattle Police Department.
- Road Segment Counts: A set of vehicle volumes in specific locations, based on the hundreds of traffic volume counts we conduct across our city each year.
- Intersection Counts: The number of people turning and crossing at key intersections, based on the hundreds of intersection counts we conduct across our city each year. These are also referred to as turning movement counts.
This data helps our planners and engineers improve the safety of our roadways for all users.
