      <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</abstract>
      <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)</purpose>

        <srccontr>WIM/ATR site information, as reported by State DOTs to the FHWA, may consist of multiple data collecting stations for a single site, each identified by a unique identifier (ID).</srccontr>
      </srcinfo>
      <procstep>
        <procdesc>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.</procdesc>
