U.S. Traffic Monitoring Location Data

State highway and transportation agencies build, operate and maintain a system of traffic count stations to monitor roadway usage by obtaining vehicle volume, vehicle class, and vehicle weight information. These traffic monitoring stations can be either permanent or temporary (portable). Permanent traffic monitoring stations operate on a continuous basis throughout the year. Permanent stations are also referred to as continuous count stations. Temporary (portable) or short duration count stations refer to these locations where traffic counting is carried out over less than a full year. Often, short duration portable count time is 48 or 72 hours.

The following data items are associated with a given station. For detailed description and coding information on these data items, please reference 2013 FHWA TMG Guide Chapter 7 Section 7.2 at
