Administrative modification: a revision to a long-range statewide or metropolitan transportation plan, TIP, or STIP that is not significant enough to require public review and comment, redemonstration of fiscal constraint, or a conformity determination (in nonattainment and maintenance areas). Examples of administrative modifications include minor changes in the cost or initiation date of included projects.
Alternatives analysis (AA): a study required for eligibility of funding under the Federal Transit Administration’s (FTA’s) Capital Investment Grant program (49 U.S.C. 5309), which includes an assessment of a range of alternatives designed to address a transportation problem in a corridor or subarea, resulting in sufficient information to support selection by state and local officials of a locally preferred alternative for adoption into a metropolitan transportation plan, and for the Secretary to make decisions to advance the locally preferred alternative through the project development process, as set forth in 49 CFR part 611 (Major Capital Investment Projects).
Amendment: a revision to a long-range statewide or metropolitan transportation plan, TIP, or STIP that is significant enough to require public review and comment, redemonstration of fiscal constraint, and/or a conformity determination (in nonattainment and maintenance areas). Examples of amendments include the addition or deletion of a regionally significant project, or a substantial change in the cost, design concept, or design scope of an included project.
Attainment area: any geographic area considered to have air quality that meets or exceeds the U. S. Environmental Protection Agency’s (EPA’s) health standards in the Clean Air Act, as amended (42 U.S.C. 7401 et seq.). An area may be an attainment area for one pollutant and a nonattainment area for others. A ‘‘maintenance area’’ (see definition below) is not considered an attainment area for transportation planning purposes.
Available funds: for projects or project phases in the first two years of the metropolitan TIP and/or STIP in air quality nonattainment and maintenance areas, funds derived from an existing source dedicated to or historically used for transportation purposes. For federal funds, authorized and/or appropriated funds and the extrapolation of formula and discretionary funds at historic rates of increase are considered ‘‘available.’’ A similar approach may be used for state and local funds that are dedicated to or historically used for transportation purposes.
Committed funds: for projects or project phases in the first two years of a TIP and/or STIP in air quality nonattainment and maintenance areas, funds that have been dedicated or obligated for transportation purposes. For state funds that are not dedicated to transportation purposes, only those funds over which the governor has control may be considered ‘‘committed.’’ Approval of a TIP by the governor is considered a commitment of those funds over which the governor has control. For local or private sources of funds not dedicated to or historically used for transportation purposes (including donations of property), a commitment in writing (e.g., letter of intent) by the responsible official or body having control of the funds may be considered a commitment.
Conformity: the process to assess the compliance of a transportation plan, program, or project with the State Implementation Plan (SIP) for air quality. The conformity process is defined in the Clean Air Act, as amended (42 U.S.C. 7401 et seq.) and governed by the EPA under its transportation conformity rule (40 CFR part 93).
Conformity lapse: pursuant to section 176(c) of the Clean Air Act (42 U.S.C. 7506(c)), as amended, that the conformity determination for a metropolitan transportation plan or TIP has expired and thus there is no currently conforming metropolitan transportation plan or TIP.
Congestion management process: a systematic approach required in transportation management areas (TMAs) that provides for effective management and operation, based on a cooperatively developed and implemented metropolitan-wide strategy, of new and existing transportation facilities eligible for funding under title 23, U.S.C., and title 49, U.S.C., through the use of operational management strategies.
Consideration: one or more parties takes into account the opinions, action, and relevant information from other parties in making a decision or determining a course of action.
Consultation: one or more parties confer with other identified parties in accordance with an established process and, prior to taking action(s), considers the views of the other parties and periodically informs them about action(s) taken.
Cooperation: the parties involved in carrying out the transportation planning and programming processes work together to achieve a common goal or objective.
Coordinated public transit-human services transportation plan: a unified, comprehensive strategy for transit service delivery developed by public, private, and nonprofit providers of transportation and human services, with participation by the public, including people with disabilities, older adults, and individuals with lower incomes, in order to minimize duplication and maximize collective coverage. The plan is a requirement under the FTA formula programs for the Elderly and Persons with Disabilities (49 U.S.C. 5310), Job Access and Reverse Commute (49 U.S.C. 5316), and New Freedom (49 U.S.C. 5317), but may include other federal, state, or local programs.

Design concept: the type of facility identified for a transportation improvement project (e.g., freeway, expressway, arterial highway, grade-separated highway, toll road, reserved right-of-way rail transit, mixed-traffic rail transit, or exclusive busway).
Design scope: the aspects that will affect the proposed facility’s impact on the region, usually as they relate to vehicle or person carrying capacity and control (e.g., number of lanes or tracks to be constructed or added, length of project, signalization, safety features, access control including approximate number and location of interchanges, or preferential treatment for high-occupancy vehicles).
Environmental mitigation activities: strategies, policies, programs, actions, and activities that, over time, will serve to avoid, minimize, rectify, reduce, or compensate for (by replacing or providing substitute resources) the impacts to or disruption of elements of the human and natural environment associated with the implementation of a long-range statewide transportation plan or metropolitan transportation plan. The human and natural environment includes, for example, neighborhoods and communities, homes and businesses, cultural resources, parks and recreation areas, wetlands and water sources, forested and other natural areas, agricultural areas, endangered and threatened species, and the ambient air. The environmental mitigation strategies and activities are intended to be regional in scope, even though the mitigation may address potential project-level impacts. The environmental mitigation strategies and activities must be developed in consultation with federal, state, and tribal wildlife, land management, and regulatory agencies during the statewide and metropolitan transportation planning processes and be reflected in all adopted transportation plans.
Federal land management agency: units of federal government currently responsible for the administration of public lands (e.g., U.S. Forest Service, U.S. Fish and Wildlife Service, Bureau of Land Management, and the National Park Service).
