Description: WSDOT developed a Land Use Context Classification system to apply to all census blocks and highway segments in Washington State. The full dataset consists of the block layer and segment layer. This data represents the segment layer. For more information on land use context classification, see WSDOT Design Manual chapter 1102 and read our documentation (LINK). This dataset is used to aid in decision making for design, speed setting, grant determinations, and standard setting.To suggest edits to this dataset based on inaccuracies in classification, please submit a response to the Microsoft Form.Each segment and census block is first classified based on quantitative data for the block’s geography. Data used to classify blocks for both layers include:2020 U.S. Census blocks contribute the geometry to the context dataset.Longitudinal Employer-Household Dynamics (LEHD) Origin-Destination Employment Statistics (LODES) datafrom the U.S. Census provides 2022 employment data at the block level.U.S. Census provides 2020 population data at the block level.Washington State Current Parcels(2025) provides parcel-level data on land use using Department of Revenue land use codes. This is provided by the Washington State Parcels Project.Intersection data was created by WSDOT from overlaying all public roadway datasets in Washington with cleanup to remove double counted intersections.City population datafor 2025 was obtained from Washington Office of Financial Management.Moreover, the segment uses block length data created by WSDOT by overlaying all public roadway datasets in Washington and performing data cleanup.A description of how blocks and segments were initially classified based on quantitative data is available in the Land Use Context Classification report and WSDOT Segment Land Use Context Classification report.Data stewards made additional adjustments based on feedback from subject matter experts, the land use context classification definitions, and other information not included in the first step of classification based on quantitative data such as university locations. See Appendix A of the Land Use Context Classification report for more information.
