Process_Step:
Process_Description:
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 2012 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.

Attribute_Label: EST20YRDHV
Attribute_Definition:
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.

Attribute:
Attribute_Label: ESTAADT
Attribute_Definition:
The Annual Average Daily Traffic figure, for the given year, estimated by the WSDOT Transportation Data Office for the stretch of roadway the figure is provided for. The estimate is generated through the application of a computerized algorithm to available roadway and traffic count data. 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.
Attribute:
Attribute_Label: ESTTRUCKPERCENTAGE
Attribute_Definition:
Estimated Truck Percentage (Directional): The percentage of annual average daily traffic represented by trucks, as estimated by the WSDOT Statewide Travel and Collision 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.
