20080201 vector digital data The dataset contains AADT and Truck Percentage that relates to 2006. All other fields are for 2026 future projections. This dataset provides directional traffic data for application to the modified, or full design level matrix in Chapters 430, or 440 of the Design Manual to establish the appropriate design class for the Design Elements of a project. Updated DHV values and SRMPs have been added. This data set is to establish estimated project costs for budgeting purposes to the Legislature. 20060101 20061231 publication date Complete Annually -124.675220 -116.861383 49.042511 45.504772 None AADT Truck Percent Annual Average Daily Traffic Design Hour Volume DHV Traffic None This dataset should be used for project scoping only.

Olympia WA 98504-7380 US (360) 570-2381 (360) 570-2400 StCharJ@wsdot.wa.gov After Datamart extraction the following procedures were conducted: Associated growth factors from an HPMS table of growth factors by County, Functional Class, and Rural/Urban classification with each row of traffic data. Associated Design Hour factors from the 2006 Peak Hour Report table of Design Hour factors by AADT group with each row of traffic data. Applied formulas to each row of traffic data in the Datamart extraction to calculate the 20 year forecasted: Design Hour Volume (DHT), Peak Direction Design Hour Volume (DDHV), and Other Direction DHV. Updated the dataset to include the calculated forecasted: EST20YRDHV, PEAKDIRDESIGNHRVOLDDHV, and OTHERDIRDESIGNHRVOL values.

Electronic State Highway Log Data Definitions BEGARM The beginning Accumulated Route Mileage for the section. BEGMP The beginning State Route Milepost for the section. DIR Direction of Inventory: The direction of travel, in terms of direction of mileposting, that the data elements Estimated AADT (Directional) and Estimated Truck Percentage (Directional) are applicable to. Increasing Increasing side of the roadway traveling in the direction of the increasing milepost value for that alignment. Decreasing Decreasing side of the roadway traveling in the direction of the decreasing milepost value for that alignment.

EST20YRDHV 20 Year Design Hour Volume (DHV): The design hour traffic volume, representing all directions of travel combined, forecast for twenty years beyond the year the Estimated AADT (Directional) is provided for. The design hour generally represents the thirtieth highest volume hour of that year and location, although it may represent the hundredth highest volume hour on stretches of roadway that are strongly influenced by recreational travel. The data is appropriate for project scoping purposes and for design projects that do not require turning movement data. 2025 ESTAADT Estimated AADT (Directional): The Annual Average Daily Traffic figure, for the given year, estimated by the WSDOT Transportation Data Office for the stretch of roadway and direction of travel that the figure is provided for. The estimate is generated through the application of a computerized algorithm to available roadway and traffic count data, which includes the assumption that traffic volumes have a fifty-fifty directional split at roadway locations with two directions of travel. The data is appropriate for project scoping purposes. It is also appropriate, when combined with the opposite direction, 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. 12/31/2005 ESTTRUCKPERCENTAGE Estimated Truck Percentage (Directional): The percentage of annual average daily traffic represented by trucks, as estimated by the WSDOT Transportation Data Office, for the stretch of roadway and direction of travel that the figure is provided for. The estimate is generated through the application of a computerized algorithm to available roadway and traffic count data, which includes the assumption that truck traffic volumes have a fifty-fifty directional split at roadway locations with two directions of travel. The data is appropriate for project scoping purposes and for design projects that do not require turning movement data. 2005 LOC_ERROR Location errors placing on the LRS. A field that is generated by the ESRI software when placing event data against a Linear Referencing System (LRS). ESRI OBJECTID Internal feature number set by software. ESRI Sequential unique whole numbers that are automatically generated. Shape Feature geometry. ESRI Coordinates defining the features. PEAKDIRDESIGNHRVOLDDHV Peak Direction Design Hour Volume (DDHV): The traffic volume forecast for the highest volume direction of travel during the design hour. This volume applies to either the decreasing or increasing direction of travel but not to both at the same time. The data is appropriate for project scoping purposes and for design projects that do not require turning movement data. 2025 RRQ State Route Related Roadway Qualifier - Related roadway qualifier uniquely identifies related roadway types for a state route.
