Description:

            Abstract:

The National Highway Planning Network is a comprehensive network database of the

nation's major highway system.  It consists of over 400,000 miles of the

nation's highways comprised of Rural Arterials, Urban Principal Arterials and 

all National Highway System routes. The data set covers the 48 contiguous States

plus the District of Columbia, Alaska, Hawaii, and Puerto Rico. The nominal

scale of the data set is 1:100,000 with a maximal positional error of ±80

meters.

Data_Set_Credit:

The NHPN Version 3.0 database was created on behalf of FHWA by members of the

Geographic Information Systems Laboratory, Systems Development Institute, The

University of Tennessee, Knoxville

 

Data_Quality_Information:

      Attribute_Accuracy:

            Attribute_Accuracy_Report: 

The accuracy of the fields FCLASS and STRAHNET from the description section of

the line shapefile is consistent with State supplied information for the years

1992 and 1993. The accuracy of the fields MILES, KM, SIGN1, and NHS from the

description section of the line shapefile is consistent with State supplied

information for the years 1992 through 2001. All other attributes in the

description of the link table are unverified. 

Logical_Consistency_Report:

All node and link topological relationships and uniqueness of entity IDs are

verified by computer algorithm.    

Completeness_Report:

The complete urban principal arterial system and arterials in rural areas as

reported to FHWA by December 1992 are inventoried in the database.  The complete

National Highway System is as reported to the FHWA by September 2000. Functional

classes below arterial vary on a State by State basis.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The elements of the NHPN have been conflated to the 1:100,000 DLG-3 data set

which maintains a nominal accuracy of at least +/-80 meters. Where new roads

have been added which are not in the DLG-3 database link alignments have been

digitized or converted from digital sources acquired from State DOTs with a map

scale of at least 1:100,000.

                           4 - Adjusted Small Urban Area

                          10 - State Border

                          Note: The values for BNDRY are additive and can be used to

                          describe a node which lies on the border of more than

                          one boundary. For example a node at a State border will

                          also be a county border node and will therefore, have a

                          value of 1 + 10 = 11.  Similarly a node which lies on

                          the boundary of an Urbanized Area and a small urban

                          area will have a BNDRY value of 4 + 2 = 6. If it were

                          also a county boundary it would have a value

                          of 1 + 2 + 4 = 7.

Format_Information_Content:

The BTS standard format for spatial data is an interim format for distributing

National Transportation Atlas Databases pending final approval of an SDTS

Transportation Network Profile (TNP).  The BTS standard format consists of a

linked set of ASCII fixed record length files.  File formats and data dictionary

for the BTS standard format are described in the document, National

Transportation Atlas Data Dictionary and Database Formats', September 1995. 

Copies of this documentation are distributed with each National Transportation

Atlas Database.
