Sec. 940.3  Definitions.

    Intelligent Transportation System (ITS) means electronics, 
communications, or information processing used singly or in combination 
to improve the efficiency or safety of a surface transportation system.
    ITS project means any project that in whole or in part funds the 
acquisition of technologies or systems of technologies that provide or 
significantly contribute to the provision of one or more ITS user 
services as defined in the National ITS Architecture.
    Major ITS project means any ITS project that implements part of a 
regional ITS initiative that is multi-jurisdictional, multi-modal, or 
otherwise affects regional integration of ITS systems.
    National ITS Architecture (also ``national architecture'') means a 
common framework for ITS interoperability. The National ITS Architecture 
comprises the logical architecture and physical architecture which 
satisfy a defined set of user services. The National ITS Architecture is 
maintained by the United States Department of Transportation (DOT) and 
is available on the DOT web site at http://www.its.dot.gov.
    Project level ITS architecture is a framework that identifies the 
institutional agreement and technical integration necessary to interface 
a major ITS project with other ITS projects and systems.
    Region is the geographical area that identifies the boundaries of 
the regional ITS architecture and is defined by and based on the needs 
of the participating agencies and other stakeholders. In metropolitan 
areas, a region should be no less than the boundaries of the 
metropolitan planning area.
    Regional ITS architecture means a regional framework for ensuring 
institutional agreement and technical integration for the implementation 
of ITS projects or groups of projects.
    Systems engineering is a structured process for arriving at a final 
design of a system. The final design is selected from a number of 
alternatives that would accomplish the same objectives and considers the 
total life-cycle of the project including not only the technical merits 
of potential solutions but also the costs and relative value of 
alternatives.
