IDENTIFICATION INFORMATION

Data Set Identity: Freight Analysis Framework (FAF) Network Version 2.2

Identification Code: None

Data Set Description: The spatial component of the FAF 2.2 network is derived from National Highway Planning Network Version 2005.08 and contains National Highway System (NHS), National Network (NN) and several intermodal connectors as appropriate for the freight network modeling. The network consists of over 447,407 miles of equivalent road mileage. The data set covers the 48 contiguous States, Alaska, Canadian routes that connects Alaska to the contiguous States and the District of Columbia. The nominal scale of the data set is 1:100,000 with a maximal positional error of ±80 meters.

Ending Date of Information Content: 20070330

Thematic Quality:

Thematic Accuracy Report: State Highway Performance related attributes associated with the FAF 2.2 network is current to HPMS 2002 dataset.

Logical Consistency Report: All node and link topological relationships and uniqueness of entity IDs are verified by computer algorithm.

Completeness Report: The completed FAF 2.2 network was delivered to the FHWA on Match 2007.

Positional Quality:
Horizontal Positional Quality

Horizontal Positional Accuracy Report: As reported in the NHPN version 2005.08 metadata, 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.
