Description:

Abstract:

This is an extract from the State Highway Log that shows median widths and barrier and surface types along State Routes. 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.

Purpose:

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.

Supplemental_Information:

Additional information can be found in the "State Highway Log", Electronic State Highway Log Data Definitions.doc, and the DOTarmcalc01.txt through the Point of Contact below. This data reflects the corresponding annually published State Highway Log Planning Report.

Attribute_Accuracy_Report:

Values were obtained from the Transportation Information and Planning Support (TRIPS) database.

Completeness_Report:

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.

Lineage:

Process_Step:

Process_Description:

Data originated from the TRansportation Information and Planning Support (TRIPS) mainframe database which in turn then feeds into a sequel database which offers greater flexibility in reporting. The information is then extracted and exported into the Excel format.

Process_Step:

Process_Description:

The excel spreadsheet was imported into a file geodatabase. From the file geodatabase, route events were created for the corresponding routes. Route events were exported into feature classes, merged into one data set, and duplicate records were dissolved.

Detailed_Description:

Entity_Type:

Entity_Type_Definition: Median widths and barrier and surface types.

Attribute:

Attribute_Label: MedianWidth

Attribute_Definition:

Distance from inside shoulder edge to inside shoulder edge on a divided highway (median width includes inside shoulders). Measured in feet.

Attribute_Definition_Source: WSDOT "Meta Data" Catalog

Attribute:

Attribute_Label: RouteIdentifier

Attribute_Definition:

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

Attribute_Definition_Source: WSDOT Application - DOTS

Attribute:

Attribute_Label: BeginStateRouteMilepost

Attribute_Definition:

A logical number, assigned by a Linear Referencing Method, to the beginning of a roadway segment along a State Route. This value will always match the Accumulated Route Mileage value unless there has been a realignment or jurisdictional transfer which changes the length of a route.

Attribute_Definition_Source: WSDOT Application - DOTS

Attribute:

Attribute_Label: EndStateRouteMilepost

Attribute_Definition:

A logical number, assigned by a Linear Referencing Method, to the end of a roadway segment along a State Route. This value will always match the Accumulated Route Mileage value unless there has been a realignment or jurisdictional transfer which changes the length of a route.

Attribute_Definition_Source: WSDOT Application - DOTS

Attribute:

Attribute_Label: BeginAheadBackIndicator

Attribute:

Attribute_Label: EndAccumulatedRouteMile

Attribute_Definition:
