Description:

Abstract:

The spatial component of the FAF network is derived from National Highway Planning Network Version 3.0 and contains National Highway System (NHS), National Network (NN). It also contains 3,436 of non-roadway dummy links. The network consists of over 274,154 miles of equivalent road mileage. The data set covers the 48 contiguous States plus the District of Columbia. The nominal scale of the data set is 1:100,000 with a maximal positional error of ±80 meters.

Purpose:

The FAF network has several Intermodal connectors as appropriate for the freight network modeling.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The FAF network retains NHPN V3 attribute fields of FCLASS, RUCODE, STATUS, SIGN1, SIGN2, SIGN3, LNAME, STFIPS, ORNLID, MILES and NHS. All other fields listed in the NHPN 3 metadata are dropped. The accuracy of these fields is consistent with NHPN Version 3.0 except the MILES attribute values. The accuracy of field "MILES" is unverified and may have distorted during modification of the network for modeling purpose. New fields added to FAF network are, ID, DIR, LENGTH, and LINK_TYPE. The field "ID" is used to join the freight modeling algorithm variables for assignment as well as assignment outputs for thematic display purpose. The mileage reported in the field "LENGTH" is based on great circle distance. The LINK_TYPE field differentiates the network's "dummy" link with other NHPN V 3 links in the FAF network.

Logical_Consistency_Report:

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

Completeness_Report:

The completed FAF network was delivered to the FHWA on October 2002.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

As reported in the NHPN version 3 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.

Process_Step:

Process_Description:

In total 3436 "dummy" centroid connector links are added to the FAF network of road links. These dummy links are straight-line connectors from trip origin/destination points to a nearest FAF road link and should not be interpreted as real road links. These links can be identified with field "LINK_TYPE" and a value of "99". These links are not a real roadway links and are normally referred to as "dummy" link for network modeling purposes. No attribute information is populated for these links except for the Fields LINK_TYPE, DIR and LENGTH.
