Smart Transportation Advancement and Transition Act or the STAT Act This bill revises and permanently reauthorizes the Intelligent Transportation Systems Advisory Committee of the Department of Transportation (DOT). DOT, in coordination with the advisory committee, must report on its efforts to engage local communities, metropolitan planning organizations, regional transportation commissions, and multi-jurisdictional groups, including in rural areas, on advancing data and intelligent transportation systems technologies and other smart cities solutions. Additionally, DOT must create, publish, and maintain a resource guide that is designed to assist states and local communities in developing and implementing intelligent transportation technology or smart community transportation programs. DOT and the advisory committee must issue a revised community resource guide at least once every three years.
