Description:

Abstract:

The Auto Ramp Facilities database is a geographic database of terminals where motor vehicles are transferred between rail and highway modes and/or between rail and water modes in the continental United States. Attribute data specify the intermodal connections at each facility; i.e., the modes involved in the intermodal transfer, the AAR reporting marks of the railroad serving the facility, the type of cargo (in this case, motor vehicles), and the direction of the transfer.

Purpose:

The database provides location and attribute information for use in national and regional cartographic and network analysis applications.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attribute data were extracted from the Association of American Railroads' Motor Vehicle Loading and Unloading Terminals directory, U.S. Army Corps of Engineers Port Series Reports, and various transportation news sources both in print and on the Internet. Attribute data reflect conditions at auto ramp facilities during mid-1995 and are subject to frequent change. Some facilities included in the database may now be dormant or permanently closed.

Logical_Consistency_Report:

All point records are represented by a single coordinate pair and a unique feature identifier of the form SSCCC-NNNN, where SS is the 2-digit State FIPS code, CCC is the 3-digit county FIPS code, and NNNN is a sequence number within the state/county. Attribute data are matched to specific point records using this identifier.

Completeness_Report:

The database includes auto ramp facilities and marine automobile terminals with rail connections which were listed or cited in one or more of the following sources: Association of American Railroads' Motor Vehicle Loading and Unloading Terminals directory, U.S. Army Corps of Engineers Port Series Reports, and various transportation news sources both in print and on the Internet. The database reflects the status of auto ramp facilities as of mid-1995. Because of the frequent turnover of this type of facility, some of the terminals included in the database may now be dormant or permanently closed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The locations of auto ramp facilities were determined using available facility address information and MapExpert, a commercial nationwide digital map database and software package, and recording the longitude/latitude of the approximate center of the facility. Facility locations are not bound to any current or previous highway, railway, or waterway network models.

Process_Description:

Auto ramp facilities identified from various sources were located using MapExpert, a commercial nationwide digital map database and software package, supplemented with other available spatial reference aids, including paper maps, aerial photographs, and published railroad atlases. The computer pointing device cursor was placed over the approximate location of the terminal and the displayed longitude/latitude was recorded. Attribute data were appended to each point.
