Historically, federal funding for transportation investment in the United States has been provided through multiyear authorization acts providing predictable levels of funding to state departments of transportation (DOTs) and local transportation agencies, including metropolitan planning organizations (MPOs). During the past 25 years, federal funding has become less certain.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 1004: Federal Funding Uncertainty in State, Local, and Regional Departments of Transportation: Impacts, Responses, and Adaptations describes the history of federal funding uncertainty; explores its impacts on state, regional, and local DOTs; and analyzes the strategies to mitigate these impacts.
Supplemental to the report is a PowerPoint Summary.
