As the designated Metropolitan Planning Organization (MPO) for Imperial, Los Angeles, Orange, Riverside, San Bernardino and Ventura Counties, SCAG is mandated by the federal government to develop a multimodal long-range transportation plan that provides a 20-year vision for investing in our transportation system, and update it at least once every four years. Our plan, the Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), addresses all modes of our transportation system, and reflects research and policy initiatives from each mode: active transportation, aviation and airport ground access, corridor planning, goods movement, high-speed rail, intelligent transportation systems, safety and security, transit, and transportation finance.
