TIGER/Line 2016 Road Coverage
August 2016 .. new resources for updated roads for geographic reference, statistical mapping, routing logistics/optimization and related operations .. See the 2016 digital map database main page for general information and related geography.
The 2016 digital map database includes many types of files and data. The data are developed in the form of shapefiles and dbase files that may be used directly with the ProximityOne CV XE GIS software at no fee. Perform wide-ranging mapping and geospatial analysis applications using these GIS resources. See more about mapping statistical data.
TIGER/Line Roads Data
This section is focused mainly on the use of the TIGER/Line "edges" shapefile. The edges shapefile U.S. wall-to-wall street/road coverage in the form of line shapefiles. Lines classified as roads are intersection-to-intersection road segments. Line segment fields include name, left- and right-side high and low addresses, and many related attributes.
Use the U.S. by county interactive table below to examine attributes of TIGER 2016 street/road coverage. ProximityOne developed these county summary data by processing each county edges shapefile. See about using the edges shapefile with the CV XE GIS software below in this section.
The following sequence of graphics shows an example of a "road segment" in context of related geography. These applications focus on an area in Kansas City, MO (Jackson County), part of the Kansas City metro. Jackson County has 52,139 TIGER 2016 road segments. See the related step-by-step summary of how you can create these and similar map views using CV XE GIS below in this section.
Road Segment Map View & Profile
- Starbucks locations are shown as red markers. The pointer is on one road segment below a Starbucks.
- This view illustrates how non-Census, non-statistical data can be integrated with TIGER geography.
- Clicking on the road segment (in a CV XE GIS operation), a mini-profile is displayed.
- The profile shows attributes of the selected road segment.
.. the TLID value shows the unique ID for this segment among all segments in U.S.
.. left- and right-side high and low address ranges and included in the profile.
Corresponding Census Block Profile
- The road segments are boundaries for census blocks.
- The census block boundaries are shown using a related TIGER blocks shapefile.
- The more that 11 million census blocks cover the U.S. wall-to-wall.
- The census block code (290950073002017) is shown as a label in the map graphic and in the profile.
Neighborhood & Shopping Area View
- A zoom-out shows the location, roads and blocks for a broader areas.
- A further zoom-out shows the focus area view in context of the metro counties (a related TIGER shapefile)
- The January 2016 Kansas City city area (orange cross-hatch pattern) is shown using a related TIGER 2016 shapefile.
TIGER/Line 2016 vintage files were released in August 2016. While many aspects of road coverage remain as described in this section, TIGER/line 2016 includes many updates as well as "new vintage" geography for school districts, state legislative districts, congressional districts and other political/statistical area geography.

TIGER Road Coverage & Attribute Availability
A limitation of TIGER/Line road coverage is that not all road segment fields are populated with the name and many have no address-related field values. This is the result of many reasons that include quality of underlying data are provided by county/regional source partners, roads that are predominately commercial and less residential and other factors.
Why this matters:
match rate can be unacceptably low for use in geocoding
location-based analyses inhibited by lower coverage addresses
absence of names and addresses limits ability for labeling in map views
Other limitations include omission of line/road segments when in fact roads do exist and road segments that are geometrically incorrect. Not covered in this section, see visual/map examples in this related section.
TIGER 2016 all lines shapefiles (34.6GB) include 68.3 million line segments (mainly roads and streams):
approximately 43.8 million line segments are roads (typically intersection to intersection).
among road segments, 31.6 million segments have a populated name field;
.. the remaining 12.2 million road segments have no name assigned.
among road segments, 17.2 million segments have an assigned left-side low address field;
.. the remaining 26.6 million segments have no address in the left-side low address field.
Data for each of these fields and others are provided for each county in the interactive table below.
