Washington State Department of Transportation 20250530 vector digital data This is an extract from the State Highway Log that shows lanes designated for acceleration movements at intersection locations. State Route identifiers and locations based on State Route Mileposts and Accumulated Route Mileage are also included for geographic reference and for use with the Washington State Department of Transportation's 24k and 500k Linear Referencing Systems. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov. To enable Geographic Information System users to more easily display and analyze a subset of the data contained in the State Highway Log in conjunction with the Washington State 24k and 500k Linear Referencing Systems. This data reflects the corresponding State Highway Log Planning Report published annually by WSDOT. 20241231 ground condition Complete Annually -124.472690 -116.994354 48.955587 45.523604 None Highway Data State Route Data Acceleration Road Log State Highway Log TRIPS Lane ISO 19115 Topic Categories transportation None 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.

Washington State Department of Transportation Version 6.2 (Build 9200) ; Esri ArcGIS 10.9.1.28388 Values were obtained from the Transportation Information and Planning Support (TRIPS) database. The data contained within the State Highway Log is collected and updated using contract plans, field reviews and information provided by numerous WSDOT Regional and Headquarters offices as well as other county and city sources over the course of a year. This data may have changed since the publication date. Only those records that have a RouteID (Route Identifier) found in the Washington State Highways at 24K Linear Referencing System can be graphically placed as events. RouteIDs that have been added or revised since the completeness date of the LRS will not place, nor will RouteIDs for road features not carried by the LRS. Positional accuracy of this data set has not been determined The Roadway Datasets are extracted from the Roadway Datamart using SQL queries and stored as Excel spreadsheets. These spreadsheets are placed as events on the StateRouteLRS data layer using the ArcGIS Display Route Events function with route names that include the direction of travel ( i, d). The event layers are converted to feature classes and loaded into an SDE database for publication.

AccelerationLaneLength Length, in miles, of the acceleration lane. WSDOT RouteIdentifier A unique Route identifier to identify a route (City,County State, Tribal, Forest) in any given data set. For State Routes, Route IDs are assigned by WSDOT's GIS and Roadway Data Office WSDOT Application - DOTS StateRouteMilepost A logical number, assigned by a Linear Referencing Method, to a given point along a State Route. This value will always match the Accumulated Route Mileage value unless there has been a realignment or a jurisdictional transfer which changes the length of a route. WSDOT Application - DOTS AheadBackIndicator An indicator that denotes if the Milepost is within a back mileage equation area. A back mileage equation area occurs when a segment of a route is added at any point other than the end of an existing route, or when a realignment occurs. WSDOT Application - DOTS A Ahead B Back AccumulatedRouteMile The measure of a point along the length of a route in which the distance is measured as an accrual of mileage from the beginning of the route WSDOT Application - DOTS SnapshotDate The date of a point in time that data was fixed or a "snapshot" taken of the data. WSDOT Application - DOTS LRSDate The Linear Referencing System date that this record is using for location. WSDOT Application - DOTS TrffcwayFeatOrientCd A code that represents a position of a feature, event, or traffic impact relative to the Trafficway from the increasing direction of travel. WSDOT Application - DOTS L Left LC Left center RC Righr center R Right B Both SHAPE Feature geometry. Esri Coordinates defining the features. AccelerationLaneWidth Width, in feet, of the acceleration lane. WSDOT Sequential unique whole numbers that are automatically generated. OBJECTID Internal feature number. ESRI Sequential unique whole numbers that are automatically generated. This tabular data can be used with the State Route Linear Referencing System geospatial data set to depict the locations of acceleration lanes along Washington's State Routes.
