Laying out a Vision for ARPA-I

ARPA-I's vision for transforming America's infrastructure

America needs transportation that is safe, secure, efficient, and resilient, while achieving net-zero emissions and increasing equity and access to mobility for all. Delivering that vision will require bold new investments in advanced and emerging materials, structures, components, systems, and capabilities – both physical and digital – that have the potential to radically transform our transportation infrastructure. 
Adapting the successful innovation model pioneered by DARPA and ARPA-E, the U.S. Department of Transportation (DOT) is accelerating the future of America’s transportation systems by launching the Advanced Research Projects Agency - Infrastructure (ARPA-I). As a newly designated agency, ARPA-I will fund high-risk, high-reward next-generation transportation technologies that will maintain America’s position as a global leader in the sector.
