Policy Papers

Informed, research-driven policymaking is central to improving our transportation sector. Our expertise in this area helps guide civic leaders to harness the power of intelligent transportation systems, while managing the inherent risks and protecting constituents. Based in the rigorous, cutting-edge findings of CMU faculty and drawing upon Heinz College’s expertise in data-driven public policy, our policy papers are a roadmap for the future of transportation legislation.
