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.

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.

Placed extracted datasets onto the 2023 Linear Referencing System (LRS) using route events. Data was placed on the Increasing 24k 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.
