The Surface Transportation Policy Partnership (STPP) is a national collaborative dedicated to fostering safer communities and smarter transportation choices that enhance the economy, improve public health, promote social equity, and protect the environment. STPP monitors trends, emerging issues, and policy proposals related to transportation planning and implementation across the United States, with a focus on safety, environmental concerns, and sound asset management. In addition to its advocacy efforts, STPP convenes a diverse group of transportation experts through the STPP Forum to assess challenges and promote transportation reform. The organization also manages ongoing initiatives such as the One Rail Coalition and the National Park Service Transportation Project, aiming to address critical transportation issues effectively.
