Twin Cities Area Transportation Study (TwinCATS)

The Twin Cities Area Transportation Study (TwinCATS) is the designated Metropolitan Planning Organization (MPO) for the Benton Harbor-St. Joseph urbanized area. MPO exist for all urbanized areas with a population of 50,000 or greater as designated by the United States Census.


TwinCATS has two committees, the Technical Advisory Committee (TAC) and the Policy Committee.  These two committees work cooperatively to make transportation related decisions for the Benton Harbor-St. Joseph urbanized area.  The Committees are made up of local representatives, transit providers, citizen reps, and elected officials from the TwinCATS member municipalities listed above.  Also on these Committees are representatives from the Michigan Department of Transportation (MDOT) and Federal Highway Administration (FHWA).
