The Annual Highway Report is based on spending and performance data submitted by state highway agencies to the federal government for 2013. For more details on the calculation of each of the 11 performance measures used in the report, as well as the overall performance measure, please refer to the appendix in the main report. The report’s dataset includes Interstate, federal and state roads but not county or local roads. All rankings are based on performance measures that are ratios rather than absolute values: the financial measures are disbursements per mile, the fatality rate is fatalities per 100 million vehicle-miles of travel, the urban congestion measure is the annual delay per auto commuter, and the others are percentages. For example, the state ranking 1st in deficient bridges has the smallest percentage of deficient bridges, not the smallest number of deficient bridges.
