This project focused on providing SANDAG with the latest research, data, and tools that can be used to support the development of the SANDAG 2021 Regional Transportation Plan (RTP), with a focus on identifying how the advances in technology, coupled with public policy can enable the region to rethink and to maximize the coordination between land use and transportation planning and, in particular, operationalizing off-model methodologies for use in SANDAG’s submission of the Sustainable Communities Strategy (SCS) methodology to the California Air Resources Board (CARB).
