Welcome to the homepage for the Regional ITS Architecture for Metropolitan
Boston. The Commonwealth, through the Massachusetts Department of
Transportation (MassDOT), Office of Transportation Planning, has developed
this architecture in cooperation with agencies and organizations involved
in transportation throughout the region.
This architecture serves a framework for transportation systems
integration in the Greater Metropolitan Boston area. For the architecture
development process, "Metropolitan Boston" was defined as the area
generally within I-495, Boston's outer circumferential highway, covering
approximately 2,000 square miles, and including Boston, Northern
Middlesex, and Merrimack Valley MPO regions, as well as portions of the
Old Colony and Southeastern Massachusetts MPO regions. For an explanation
of the Architecture Development Process, click here. For a Summary of Changes
made to the architectures in 2010, click

available in the Project Documents section of
this website.
This Regional ITS Architecture identifies the existing and planned ITS
components in the region and the interfaces among them. Collectively,
these components and interfaces define a framework for planning and
deployment of ITS in the region. This architecture has a time horizon of
up to fifteen years, with particular focus on those systems and interfaces
that are likely to be implemented in the next ten years. Components in the
architecture are classified as either "existing" or "planned." Components
classified as "existing" are those whose interface design is complete,
regardless of whether the actual element or interface is implemented.
Components classified as "planned" are those whose interfaces have not yet
been designed.
This architecture is a valuable tool for those who plan, design,
implement, and operate intelligent transportation systems. Moreover, it
provides the basis for satisfying federal architecture consistency
requirements for ITS projects. It is important to recognize, however, that
an ITS project, like any other transportation project, is developed within
the region's existing transportation planning process. As such, ITS
project proponents must still work with their regional planning partners
and follow the established regional planning process in developing their
ITS project.
While the architecture has relevance throughout the project development
process, this website focuses on the initial review for architecture
consistency in the early stages of the process. The following links
