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
