A bill to amend title 23, United States Code, to require the Secretary of Transportation to develop a national infrastructure intelligence tool for congestion mitigation, and for other purposes.

S. 3906 would direct the Secretary of Transportation to create a national infrastructure intelligence tool designed to help identify and address traffic congestion across the country. The bill, introduced by Senator John Cornyn of Texas in February 2026, is currently in the committee review stage and has not yet been voted on by the full Senate.

If enacted, this legislation would establish a system for analyzing congestion patterns and potentially inform transportation planning and infrastructure decisions at the federal level. The practical impact on citizens would depend on how such a tool is implemented and whether it leads to targeted improvements in high-congestion areas. The bill is standard legislation that would require presidential signature to become law.
