Washington State Department of Transportation 20170615 vector digital data The dataset contains estimated AADT that relates to 2016. A data set to provide 2016 estimated Annual Average Daily Traffic volumes along the state highway system. Data represents all directions of travel for the given roadway segment. To fulfill federal reporting requirements and help meet departmental point-specific traffic information needs. 20160101 unknown 20161231 unknown publication date Complete Annually -124.674937 -116.861308 49.042695 45.504776 None Annual Average Daily Traffic AADT None 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.

Version 6.2 (Build 9200) ; Esri ArcGIS 10.4.1.5686 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. 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. Washington State Department of Transportation Joe St. Charles mailing

Data was placed on the Increasing 24k Linear Referencing System (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. Vector Complete chain 5039 OBJECTID Internal feature number. Esri Sequential unique whole numbers that are automatically generated. Location Text description of the segment boundaries in terms of the State Route Milepost and Ahead/Back Indicator of physical features of the roadway (e.g., an intersection or bridge). AADT The annual average daily traffic figure calculated by the WSDOT Travel and Analysis Branch for the roadway location and year indicated. 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 StateRouteNumber The number assigned to the State Route and enacted into law by the Washington State Legislature RelatedRouteType A Code that represents a a classification of a route associated with a mainline state route, examples include: Couplet, Spur, Alternate Route, etc.  Mainline WSDOT Application - DOTS AR Alternate Route WSDOT Application - DOTS CD Collector - Distributor - Decreasing WSDOT Application - DOTS CI Collector - Distributor - Increasing WSDOT Application - DOTS CO Couplet WSDOT Application - DOTS FD Frontage Road - Decreasing WSDOT Application - DOTS FI Frontage Road - Increasing WSDOT Application - DOTS FT Ferry Terminal WSDOT Application - DOTS FS Ferry Ship (boat) WSDOT Application - DOTS HD Grade separated HOV Lane - Decreasing WSDOT Application - DOTS HI Grade separated HOV Lane - Increasing WSDOT Application - DOTS LX Crossroad within Interchange WSDOT Application - DOTS PR Proposed Route WSDOT Application - DOTS RL Reversible Lane WSDOT Application - DOTS SP Spur WSDOT Application - DOTS TB Transitional Turnback WSDOT Application - DOTS TR Temporary Route WSDOT Application - DOTS UC Under Construction WSDOT Application - DOTS P1-P9 Off Ramp - Increasing, P4 contained only within Urban Interchanges WSDOT Application - DOTS Q1-Q9 On Ramp - Increasing, Q4 contained only within Urban Interchanges WSDOT Application - DOTS R1-R9 Off Ramp - Decreasing, R4 contained only within Urban Interchanges WSDOT Application - DOTS S1-S9 On Ramp - Decreasing, S4 contained only within Urban Interchanges WSDOT Application - DOTS RelatedRouteQualifier A reference used to uniquely identify the physical location of the State Route Related Route Type. The State Route Related Route Qualifier can be based on a State Route Milepost, street name, city, or other distinguishing geographic reference. BeginAccumulatedRouteMile The measure of a point at the beginning of a roadway segment along the length of a route in which the distance is measured as an accrual of mileage from the beginning of the route. The Accumulated Route Mile Begin may define the starting point for a business activity or measurement. For example, project location or roadside event. EndAccumulatedRouteMile The measure of a point at the end of a roadway segment along the length of a route in which the distance is measured as an accrual of mileage from the beginning of the route. The Accumulated Route Mile Begin may define the starting point for a business activity or measurement. For example, project location or roadside event.
