Source and Accuracy Compendium

Each of the U.S. Department of Transportation's (DOT) performance measures below links to the associated Source and Accuracy Statement(s) for the data used to compute the measure. Note that measures in the form of rates link to two or more Source and Accuracy Statements since they combine data from different sources in the numerator and denominator of the rate. A small number of Source and Accuracy Statements have yet to be completed. They will be added to this compendium upon completion.

Safety Measures

1. Fatalities per 100 million vehicle-miles traveled
2. Fatalities per 100 million large truck vehicle-miles traveled
3. Fatal aviation accidents (U.S. commercial air carriers) per 100,000 departures
4. Number of general aviation fatal accidents
5. Train accidents and incidents per million train-miles
6. Transit fatalities per 100 million passenger miles traveled
7. Incidents for natural gas and hazardous liquid pipelines
8. Number of serious hazardous materials incidents in transportation

Mobility Measures

9. Percentage of miles on the National Highway System (NHS) that meet pavement performance standards for acceptable ride

Environmental Stewardship Measures

18. On a program-wide basis - acres of wetlands replaced for every acre affected by Federal-aid highway projects (where impacts are unavoidable)
19. Percentage of DOT-owned facilities categorized as No Further Remedial Action Planned (NFRAP) under the Superfund Amendments and Reauthorization Act (SARA)

25. For major DOT systems acquisitions, percentage of cost, schedule, and performance goals established in acquisition project baselines that are met
26. Percent share of the total dollar value of DOT direct contracts that are awarded to women-owned businesses
27. Percent share of the total dollar value of DOT direct contracts that are awarded to small disadvantaged businesses
28. Percentage of major Federally-funded infrastructure projects that meet schedule milestones established in project or contract agreements, or miss them by less than 10%
29. Percentage of major Federally-funded infrastructure projects that meet cost estimates established in project of contract agreements, or miss them by less than 10%
30. Percentage of transit grants obligated within 60 days after submission of completed applications
