In metropolitan areas, the transportation plan is the statement of the ways the region plans to invest in the transportation system. Per federal regulations, the plan shall "include both long range and short-range program strategies and actions that lead to the development of an integrated, intermodal transportation system that facilitates the efficient movement of people and goods."
The plan addresses:
- Policies, strategies, and projects for the future
- A systems level approach by considering roadways, transit, non-motorized transportation, and intermodal connection
- Projected demand for transportation services over 20 years
- Regional land use, development, housing, and employment goals and plans
- Cost estimates and reasonably available financial sources for operation, maintenance, and capital investments
- Ways to preserve existing roads and facilities and make efficient use of the existing system
The Metropolitan Transportation Plan (MTP) and the long-range statewide transportation plan must be consistent with each other. The MTP must be updated every five years in air quality attainment areas or every four years in non-attainment or maintenance areas.
MPOs should make special fforts to engage interested parties in the development of the plan. Finally, in cases where a metropolitan area is designated as a non-attainment or maintenance area, the plan must conform to the SIP for air quality.
