- Abstract
- Automatic Traffic Recorders (ATR) is a point theme representing Weigh-in-Motion (WIM), and Automatic Traffic Counters (ATR) in the United States The data included in the GIS Traffic Stations Version database have been assimilated from station description files provided by FHWA for Weigh-in-Motion (WIM), and Automatic Traffic Counters (ATR). Location referencing information was derived from the National Highway Planning Network version 4.0. and State offices of Transportation The attributes on the point elements of the database have come from two primary sources, the Station Description Records and the National Highway Planning Network's Linear Referencing System. The attributes for these databases have been intentionally limited to location referencing attributes since the core station description attribute data are contained within the Station Description Tables (SDT). There is a separate Station Description Table (SDT) for each of the different station types; WIM, and ATR. The attributes in the Station Description Table correspond with the Station Description Record found in Chapter 6 of the latest Traffic Monitoring Guide. The SDT contains the most recent stations available for each state and station type. This table was derived from files provided UTCTR by FHWA. The Station Description Table can be linked to the station geopackage via the STNNKEY field . A single exception table containing records for those stations that could not be located is provided for WIM, and ATR stations. Generally, this table contains records where location descriptions were not clear enough to locate a station. It is hoped that FHWA will be able to contact the States for a more detailed description
- Purpose
- The GIS Traffic Stations database provides structural linkages between the National Highway Planning Network Weigh In Motion (WIM), and Automatic Traffic Count Stations (ATR)

- Data Quality Information
- Attribute Accuracy Report
- Weigh Station attributes were obtained from the individual State DOTs, University of Tennessee data, National Highway Planning Network, Federal Highway Administration, and RITA (Research and Innovative Technology Administration). All records were assigned the accurate state name, state abbreviation, state FIPS code and county FIPS code.
- Logical Consistency Report
- Uniqueness of entity Ids are verified by computer algorithm.
- Completeness Report
- The data are as complete as possible. There are approximately 25 stations that could not be located due to a poor location description.
- Horizontal Positional Accuracy Report
- The elements of the GIS Traffic Stations have been conflated to the 1:100,000NHPN v4.0 data set which maintains a nominal accuracy of at least 80 meters. Where no NHPN roads exist, the station was located using text description or teleatlas data.
