Weigh-in-Motion (WIM) Stations

Description

The Weigh-in-Motion (WIM) Stations dataset was updated on December 31, 2024 from the Federal Highway Administration (FHWA), with attribute data from the end of calendar year 2024 and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The data included in this database is provided by the Federal Highway Administration (FHWA) for Weigh-in-Motion (WIM), and can be found via the FHWA Weight Station Map (https://doi.org/10.21949/7e9e-gw75). WIM is a primary technology used for monitoring vehicle weights and axle loads on roadways. Weighing vehicles in motion is done by capturing data as vehicles drive over sensors installed in a roadway or under a bridge. Aggregated summary statistics including annual truck (class 4-14) counts and weights (in tenth of a metric ton) are also included. Summary statistics were derived from WIM data for all sites in the US that are in the FHWA Travel Monitoring Analysis System (TMAS).Traffic loading data is collected for each vehicle that passes over a WIM sensor and includes wheel (single or dual tires) loads, axle loads, and gross vehicle weights (GVW). In addition, WIM sensors collect traffic volume, axle spacings, vehicle classification, and speed data.

A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/180Q-FC93
