  Description:
    Abstract:
      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 shapefile 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:
    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.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      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.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report: The elements of the GIS Traffic Stations have been conflated to the 1:100,000 NHPN 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.

    Process_Step:
      Process_Description: The station location description for each station type WIM, ATR, and Classification was used to manually adjust a station to the National Highway Planning Network (NHPN) v4.0. Any stations that could not be located on the NHPN were located on TIGER 99. Any stations that could not be located due to poor location descriptions are contained in the exception data table delivered with the GIS Traffic Stations.

    Process_Step:
      Process_Description:
        Weigh Station collection began with FHWA delivering all new weigh station points ot RITA.  Also acquried was the older University of Tennessee dataset to use as a comparison with new FHWA data.  Analysis of data began by comparing the two datasets.  All duplicate points were elimitnated from the new FHWA dataset.  Once a final dataset was complete, a state-by-state analysis began.  As each state's database was populated differently, analysis varied from state to state.  
        Process steps included indentifying county code per point. Determine broad location of road segment using LRS Id.  Value could then be tied into the LRSKEY value on road segments.
        If no LRS ID was provided, HPMS values were also used to determine location.
        Finally, an exact point was determined by using the provided text description within the location field.
        Once exact location was determined, edit session was begun and the point was manually created.
        After all points were populated, the latitude and longitude fields were calculated using a script in an edit session.
        The AADT and FCLASS were appended by using the STTNKEY attribute.
        Standard quality control processes performed in preparation for publication.
