The Roadway Data page provides a bounty of data such as locational information, jurisdiction, functional classification, surface type, and reference points; control section records and construction project logs.
The roadway data is subject to ongoing revisions which result in differences in the information presented on reports over time. Several reports are based on the most current data; therefore, the information is subject to change. To allow for consistency, the VMT and Mileage reports on this web page are based on a "snapshot" of the data which is taken during every December (prior to 2017, snapshots were taken mid-year) to align with the Highway Performance Monitoring System (HPMS) submittal. Therefore, the statistics remain constant until another snapshot is taken. The data and statistics presented may vary from the information obtained from other sources.

(Centerline) Miles and Lane Mileage - Centerline Miles is a term for one mile of a single roadway, regardless of the number of lanes. (If a road is divided, mileage is not doubled.) Lane Mileage refers to a multiple of continual driving lanes and centerline mileage. Both types of figures can be organized by city, county, route system, surface type, and functional class.
Data | Methods
Roadway Project Mapping Application (RPMA) - used to determine the begin and end points and Carto measures (used to be referred to as "True Miles") of projects going into CHIMES using the static HPMS subset of LRS data
Trunk Highway Log Point - sequential listing of landmarks one crosses when driving along a trunk highway in the increasing (reference post) direction
NOT to be used any longer for projects going into CHIMES (highway projects starting in FY2018 or later)
Data | Methods
Functional Classification - the process by which all roads are grouped into classes or systems according to the character of service they are intended to provide
