A Unified Planning Work Program (UPWP) is a statement of work identifying the planning priorities and activities to be carried out within a metropolitan planning area. It can be updated annually or biennially. At a minimum, a UPWP includes a description of the planning work and resulting products, who will perform the work, time frames for completing the work, the cost of the work, and the source(s) of funds. Metropolitan Planning Organizations (MPOs) are required to develop UPWPs to govern work programs for the expenditure of Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) planning funds.
