This Request for Proposal (RFP) is seeking a consulting firm, or multiple-firm team, to develop fully functioning land use and travel demand models with a forecast year of 2040. Forecasting land use and travel demand is crucial in the development and updating of the Regional Transportation Plan (RTP), Transportation Improvement Program (TIP), air quality conformity determinations, and State Implementation Plan (SIP) for air quality. It also provides valuable support to various transportation planning processes conducted by its local member agencies (municipalities and counties) and the Department of Transportation (CDOT).
