Metropolitan Transportation Planning
"Federal law requires state and local governments to designate a metropolitan planning organization (MPO) in each urbanized area with a population of 50,000 or more to help plan surface transportation infrastructure and services. There are currently 381 MPOs nationwide. Despite some strengthening of their authority over the years, MPOs have generally remained subordinate to state departments of transportation (DOTs) in the planning and selecting (“programming”) of projects using federal surface transportation funds. Moreover, it can be argued that at the metropolitan level MPOs are subordinate to local governments that own and
operate many elements of the transportation system, and also control land use planning and zoning.

Because of the perceived weakness of MPOs, some in the transportation community have argued that they ought to be given much more power over the planning and programming of projects using federal surface transportation funds. Some of these observers go so far as to suggest that federal policies and programs in a number of areas, including transportation, housing, and the environment, need to be coordinated on a metropolitan scale, and that MPOs are the organizational venue where this should occur. Others argue that the relationship between state government, local government, and MPOs is well-balanced and should not be changed. A third view is that metropolitan transportation planning is controlled by planners who often harbor anticar views, and consequently, MPOs can be actually detrimental to well-functioning metropolitan transportation systems. In this view, MPOs should be abolished or, at the very least, have their functions significantly curtailed..."
