The Washington State Department of Transportation shall not be liable for any activity involving this data with regard to lost profits or savings or any other consequential damages; or the fitness for use of the data for a particular purpose; or the installation of the data, its use, or the results obtained. The data is appropriate for project scoping purposes. It is also appropriate, for (a) analyzing collision rates on stretches of roadway that are at minimum several miles in length and (b) design projects that do not include turning movement analyses.

Data_Quality_Information:

Completeness_Report:

Data is only provided for Mainlines, Spurs, Couplets, Alternate Routes, Reversible Lanes and Grade Separated HOV Lanes. These are the related roadway types for which traffic data is reported to the federal government through the Highway Performance Monitoring System.

Process_Step:

Process_Description:

Traffic and roadway data from WSDOT's Datamart, was loaded to software with code for (a) consolidating contiguous segments with the same AADT and (b) dividing segments at locations where the roadway changes from one direction of travel to two or from two directions of travel to one. Data queried on process date.

Process_Step:

Process_Description:

Placed extracted datasets onto the 2020 Linear Referencing System (LRS) using route events. Data was placed on the Increasing 24k LRS except for roadway segments with no lanes carrying traffic in the increasing direction of mileposting. These segments were placed on the Decreasing 24k LRS. Those two datasets were merged together to produce the final result.
