Title: United States Automatic Traffic Recorders (ATR), 2008
Contributors:- Point data
- 2008
- Federal Highway Administration (FHWA)
- Research and Innovative Technology Administration's Bureau of Transportation Statistics (RITA/BTS)
Summary: 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 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

Title: United States National Bridge Inventory, 2008
Contributors:- Point data
- 2008
Summary: National Bridge Inventory is a point theme representing bridges in the United States. The NBI is a collection of information (database) covering the more than 600,000 bridges located on public roads, including Interstate Highways, U.S. highways, State and county roads, as well as publicly-accessible bridges on Federal lands. It presents a State by State summary analysis of the number, location, and general condition of highway bridges within each State. Although the inventory contains locational information, it's accuracy is unverified, and in many cases the information is not provided or incorrect. Using information from the inventory, an attempt was made to conflate the bridges to a common reference network, TeleAtlas's DynaMap for Transportation. Over 75% of the inventory was successfully conflated. the remaining bridges are included in this shapefile, but are located at longitude-latitude 0-0.
