The U.S. Department of Transportation seeks industry-led prototypes to advance Cooperative Driving Automation (CDA) technology from research to commercial viability, focusing on safety and mobility in work zones, traffic incidents, cooperative perception, and emergency vehicle awareness. The effort will validate prototypes at technology readiness levels 6-7 in controlled testbeds, then progress to small-scale real-world demonstrations on public roads with mixed traffic. A presolicitation for the Broad Agency Announcement will be issued in late July 2026. No budget amounts or performance location are specified. This opportunity targets bidders capable of developing and testing pre-production CDA systems to generate data for a national deployment strategy.
