Travel Demand Model

The regional travel demand model is named as the Triangle Regional Model (TRM). It is an analytical tool to support the policy decision making process and the development of the Metropolitan Transportation Plan (MTP).  The TRM utilizes a traditional four-step trip-based model process consisting of trip generation, trip distribution, mode choice, trip assignment for the Research Triangle region of North Carolina. It is also a predictive model that can be used to forecast peak period and daily trips of automobile, transit, commercial vehicle, and non-motorized travel for any given socio-economic scenario. The four TRM stakeholder agencies are Durham-Chapel Hill-Carrboro Metropolitan Planning Organization (DCHC-MPO), Capital Area Metropolitan Planning Organization (CAMPO), North Carolina Department of Transportation (NCDOT), and GoTriangle.
