Description:
Abstract: The Fixed-Guideway Transit and Ferry Network is
a comprehensive network database of the nation's
fixed-guideway transit and ferry systems. The data
set covers systems in cities within the 48 contiguous
States plus the District of Columbia and Puerto Rico,
and includes heavy rail, light rail, monorail, ferry
boat, cable car, dedicated HOV roadway, inclined
plane, and automated guideway.
Purpose: The data provide users with information about
the location and type of fixed-guideway transit and
ferry network and terminal facilities primarily for
regional cartographic, spatial and network analysis purposes.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Attribute information was
obtained from individual transit agencies through
telephone conversations and follow-up written material
provided by the agency. The level of detail and
completeness of this information varied, depending on
the source. Attribute data were transcribed directly
into the database with no independent verification.
This version of the data set includes no node attributes.
When modifying the data set, the provider did not
consistently code the MODDATE or the REVISION field.
Logical_Consistency_Report: Networks were checked for
connectivity during database construction and again
prior to dissemination on the National Transportation
Atlas CD-ROM. Duplicate links were removed.
In the process to verify feature location based on the
NTAD STATES dataset, the verifier split a number of
line segments. Based on the attributes included in the
dataset, there is no apparent reason for these
modifications.
The data provider inconsistently coded the LINKID and
FEATURID fields when modifying the data set.
Completeness_Report: This database includes all
fixed-guideway transit and ferry lines identified by
the Federal Transit Administration as recipients of
Federal transit funding. Excluded are some small
fixed guideway systems operating without Federal
funding and certain ferry lines which may receive
Federal Highway funding in lieu of transit funding.
Attribute data is incomplete at this time, and what
data is included reflects information received from
individual transit agencies during 1994.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Right-of-ways for
fixed guideways were digitized from a variety of
source material received from individual transit
agencies. These materials ranged from engineering
drawings to stylized system maps. Based on the
material provided, alignments were traced against
TIGER/Line street networks as basemaps. At best, the
resulting alignments are no more accurate than the
TIGER/Line street network for specific urban areas.
A number of ferry lines were added that appear to cross
through islands when compared with the NTAD STATES
dataset.

Process_Step:
Process_Description: Using source materials received
from individual transit agencies, fixed guideway
centerline networks were digitized against TIGER
street networks. Stations were located using
addresses and other cues provided from the source
material. Each fixed guideway system was put in its
own database.
