Most maps generated by Planning’s GIS system include
the state road network a primary component. This
information is based on the Road Inventory file, which
serves as the foundation of Planning’s GIS capabilities.
The Road Inventory is linked to 1:5,000 Centerline files
using ArcGIS, and contains approximately 480,000 road
inventory records, representing over 36,000 centerline
miles of roadway. This system allows for mapping of
attributes in the Road Inventory file at any geographic
level (i.e., state, MassDOT Highway District, etc.). Appendix B contains a list of all the road inventory attributes.
SOURCES AND DISCLAIMER
Many of the map products described in this catalog
show data obtained from MassGIS, the clearinghouse
for all spatial data developed or maintained by the
various Massachusetts state agencies. Road attribute
data is derived from the Road Inventory File maintained
by Planning and does not constitute a legal record. The
location of features and boundaries shown on these
maps are approximate and are intended for planning
purposes only. These maps are not intended for survey,
engineering, or legal purposes.

“GIS takes geographically referenced numbers and words from
rows and columns in a
database or spreadsheet and summarizes them on a map as
points, lines or polygons.”
GIS SERVICES AVAILABLE TO MASSDOT
The need to view spatial data and presence of map-making has become vital to the
success of the Massachusetts Department of Transportation (MassDOT). The Office of
Transportation Planning (Planning) supports rising interest by offering GIS services to
all of MassDOT. This support enhances the development and exchange of spatially
related databases throughout the all aspect of state transportation. The GIS Services
group can provide a full range of services, as described in detail below.
• Customized mapping. Using ArcGIS, Planning will develop maps for your public
presentations, preliminary analyses, or field assessments. Data can be displayed in
relation to an orthophoto, the Road Inventory, or other landscape features of your
choice.
• Perform Spatial Analysis: Using the GIS tools and databases, Planning can perform
spatial analyses on one or more datasets and provide the result in tabular or map
form.
• ArcGIS Software support. Planning offers troubleshooting and “help-desk” capabilities for ArcGIS to support their continuing use within MassDOT.
• Database design and programming. Sophisticated use of GIS requires an understanding of database design and programming techniques. Planning should be
consulted for database design and programming issues related to the development
of spatial data.
GIS SERVICES GROUP OVERVIEW
The GIS Services group provides the Massachusetts Department of Transportation
(MassDOT) with all of its geographic information system (GIS) needs, which include
creating and maintaining statewide spatial databases, preparing official MassDOT
maps, conducting spatial analysis, and locating MassDOT’s assets.
Road Inventory
The GIS Services group is responsible for the official statewide road inventory database, used by MassDOT, all Massachusetts agencies that use GIS, all Massachusetts
Regional Planning Agencies, and all Massachusetts cities and towns. This database
is also used for reporting annual roadway statistics to the Federal Highway Administration for funding of statewide projects and for determining the Chapter 90 money
allocation based on road mileage. GIS Services maintains the accuracy of the road
inventory database by continually updating the spatial line work representing the
statewide roadway network and associated data.
Other Spatial Data
The GIS Services group creates and maintains other spatial databases used by MassDOT and the entire Massachusetts GIS community. These spatial databases include
project based (active construction, bicycle, etc.), asset based (park and ride, rest
areas, depots, etc) and transportation based (airports, seaports, intermodal terminals,
etc). They provide a means to track projects and assets and map the transportation
network, which serves as an important component for transportation planning activities in the Commonwealth.

National Highway System
DESCRIPTION
The National Highway System (NHS) is a
network of nationally significant highways
selected by the state and Metropolitan
Planning Organizations and approved by
Congress to ensure continuity across state
lines and connection with other priority
transportation networks. It includes the
Interstate System, Strategic Defense Highway System, other principal arterials, and
connectors to major intermodal terminals.
The roadways are color-coded according
to subcategories of the NHS and also depict all other non-NHS arterials and collectors for reference.
3
Federal Aid Program
DESCRIPTION
These maps depict roadways that are eligible for Federal Funding, under both the
National Highway System (NHS) and Surface Transportation Program. The Surface
Transportation Program includes all urban
arterials, urban collectors, rural arterials,
and rural major collectors that are not on
the NHS. Rural minor collectors are eligible
for limited STP funding under the SAFETEA-LU Program.
4
Functional Classification
DESCRIPTION
These maps depict roadways according
to their functional classification (arterial,
collector, local). The functional classification of a roadway refers to the character
of services that it is intended to provide.
In general, roads either serve to provide
mobility or access for vehicles to locations.
Planning developed the functional classification system in 1993 in cooperation with
the Metropolitan Planning Organizations
and in accordance with Section 1006(c) of
the Intermodal Surface Transportation Efficiency Act. Planning maintains the functional classification system on an ongoing
basis.
5
Arterials
Arterials provide the highest level of mobility at the
greatest vehicular speed for the longest uninterrupted distances and are not intended to provide
access to specific locations. Arterials are further
subdivided into Principal Arterials and Minor Arterials. Interstates are considered to be arterials but
are given their own category in these maps
Collectors
Collectors provide some level of both mobility and
access. They collect traffic from local roads and
funnel it to arterials. In rural areas, collectors are
further subdivided into Major Collectors and Minor
Collectors.
Local
Local roads provide access to abutting land with
little or no emphasis on mobility. The term “local
road” should not be confused with local jurisdiction. Most, though not all, functionally classified
local roads are under city or town jurisdiction.
Federal Functional
Classification
DESCRIPTION
These maps depict roadways according to
their Federal functional classification (arterial, collector, local). Federal Highway Administration developed this system as part
of the Highway Performance Monitoring
System (HPMS).
The Federal functional classification divides
roadways into the same three general categories as Planning’s functional classification system. The main difference between
the systems is that the Federal system separates the Interstates and local roadways
into urban and rural designations and
classifies limited access arterials (non-Interstates) separate from full-access arterials.
6
Jurisdiction of Roads
DESCRIPTION
These maps depict roadways according to
their jurisdiction. The jurisdiction of a roadway refers to the agency that owns it and
has responsibility for its repair and maintenance. The source for the jurisdiction data
is the Road Inventory file that contains 16
jurisdictional categories.
7
7
Jurisdictions
1. MassDOT Highway
2. City or town accepted
3. Department of Conservation and
Recreation
4. No Longer Used
5. Massachusetts Port Authority
6. State park or forest

8. Federal park or forest
9. Federal institutional
10. County institutional
11. State college or university
12. Corps of Engineers
13. Federal Bureau of Indian Affairs
14. Department of Defense
15. Other federal
16. Unaccepted
Numbered Routes
with Mile Points
DESCRIPTION
This maps show the numbered routes
across the state with the mile points shown
in one-mile increments. Both the functional classification and jurisdiction are available to identify the roadway type for each
route. Each route number starts at mile
point zero in the western or southern part
of the route and ends on the northern or
eastern terminus. If more than one route
follows the same roadway, the higher
order route would be displayed. For example, the Southeast Expressway has five
routes (I-93, US 1, Route 3, Route 1A, and
Route 3A), but the mile points would be
displayed for I-93 only.
8

and the communities included in each RTA
assessment district. The Massachusetts Bay
Transportation Authority (MBTA) has three
separate assessment districts also included
in the map.
11
MBTA Zones
Zone A and B represent communities served only by the MBTA.
Zone A represents communities
with the highest transit availability
and therefore the highest percentage assessment.
While Zone B represents communities with less transit availability
and therefore lower percentage
assessments.
Zone C represents communities
either in other RTA districts or in
none at all that pay an assessment
to the MBTA for transit access or
border a community with transit
access.

densely settled territory with the densely
settled core. MassDOT then makes adjustments to the boundaries in relation to functionally classified roads.
13
Urbanized Areas
To qualify as an urbanized area,
the territory identified according
to criteria must encompass at
least 2,500 people, at least 1,500

Bicycle Facility Definitions
Shared use paths are facilities on exclusive right-of-way with mini-
mal cross flow by motor vehicles. (5-24) “Shared use paths are designed to
accommodate a variety of users, including walkers, bicyclists, joggers, and
people with disabilities, skaters, pets, and occasionally equestrians“* for both
commuting or recreational purposes. *(p 11-1)
Greenways are recreational facilities through back country or other less
accessible areas. “These facilities are generally unpaved trails and can serve
hikers, mountain bikers, equestrians, or other off-road users.” (11-1)
On-Road Facilities are street level visible accommodations on or
along the roadway, namely bike lanes and signed bike routes.
Bicycle Lanes are portions of the traveled way designed for bicycle use
and “are one-way facilities that carry bike traffic in the same direction as
the adjacent motor vehicle traffic.” (5-20) Bicycle lanes are established with
appropriate pavement markings and signing along streets, and under some
circumstances, these lanes can also represent contra-flow bike lanes.
Signed Bicycle Routes are facilities marked with signs that are in-
tended to guide bicyclists onto or along particular roadways from a starting
location to an ending location.
Unimproved Bicycle Routes are routes without visible street level
accommodations such as bicycle lanes or road signs. These routes may be
found in commercially produced bicycle tour books, maps, or web sites. Bicyclists must bring route information with them to determine where the route
starts, traverses, and ends rather than referring to posted signs.
This category is also used for off-road accommodations, where the course or
condition is unverified.
Programmed are projects listed in Statewide Transportation Improvement
Plan, in design or under construction.
Proposed Bicycle Facilities are recommended for study or construction in
Regional Transportation Plans developed by Metropolitan Planning Organizations or from public participation during public outreach efforts.
*(Guide) refers to MassDOT Highway’s 2006 Project Development & Design
Guide.
