About This Tool

The 50-state transportation finance database and interactive map is the most comprehensive resource of its kind based on the Transportation Governance and Finance: A 50-State Review of State Legislatures and Departments of Transportation (pdf) report jointly developed with the National Conference of State Legislatures. Explore this unique module in two formats: Mapped Data, which shows interactive maps for a 2016 snapshot on Transportation Funding & Finance, Organization & Leadership, and Legislative Interaction; or Tabular Data, which shows tables for all of the mapped data plus state-by-state information on Demographics, State Roadway System, Toll Facilities, Revenue Sources, State DOT Disbursements, and Motor Fuel Taxes between 1992 and 2019. Tabular data sources include: the Census Bureau, Bureau of Economic Analysis, Bureau of Labor Statistics, FHWA Highway Statistics, American Petroleum Institute, state government websites (motor fuel tax data), and toll facility owner/operator websites.
