Created as part of the Regional Plan Association (RPA), America 2050 is a coalition partner of Transportation For America. As the national infrastructure planning and policy program for the RPA, its goal is to provide consult and leadership on a broad range of transportation, sustainability, and economic development issues. Since its start in 2005, the RPA has published a range of influential policy papers and related documents. From its homepage, visitors can look over recent tweets and then click on over to thematic areas, which include Infrastructure, Megaregions, and Commentary. The Maps area is worth a look, as well, as it includes offerings like "A Phasing Plan for High-Speed Rail" and "Underperforming Regions." Moving on, the Research area contains dozens of intriguing reports, such as "New Strategies for Regional Economic Development" and "Megaregions."
