What is an MPO?
A Metropolitan Planning Organization
, commonly referred to as an MPO, is an association of local agencies that coordinate transportation planning and
development activities within a metropolitan area. Establishment of an MPO is required by law in urban areas with
populations of more than 50,000 in order for the area to use federal transportation funding.
MPOs are established to ensure coordination and cooperation among the various jurisdictions that oversee
transportation within the urban area.
On August 10, 2005, President Bush signed into law the Safe, Accountable, Flexible, Efficient Transportation
Equity Act: A Legacy for Users SAFETEA-LU.
This is the transportation law that guides not only the funding, but the planning for transportation nationwide.
One of the fundamental regulations outlined in SAFETEA-LU is that the state and each MPO must create a Transportation
Improvement Program (TIP). The creation/decision-making of the TIP is guided by:
- A policy board, generally comprised of local elected officials and public agency officials who administer or
operate major modes of transportation, and
- A technical advisory group of professional planners and engineers who are often employees of the same agencies.
An MPO is not a level of government; however, the MPO has effective control over transportation improvements within
the area since a project must be a part of the MPO's adopted long-range plan and be placed in their metropolitan transportation
improvement program (TIP) in order to receive federal funding.
SAFETEA-LU requires that the Statewide Transportation Improvement Program (STIP) and
the TIP “mirror” each other. In other words, the federal-aid or regionally significant projects in the TIP must be reflected
in the STIP. There are six (6) metropolitan planning organizations (MPOs) in Idaho (see below). You may contact them for more
information or to get a copy of their Transportation Improvement Program (TIP). The Northern Ada County Metropolitan Planning
Area is also Idaho’s only designated transportation Management Area (TMA).
