About the National Data
Data
Data Source: Crash Report Sampling System (CRSS), DOT/NHTSA
Baseline: 2.8 vehicular crashes per 100,000,000 miles traveled involved drowsy driving in 2017
Target: 2.2 per 100,000,000
Numerator
Number of motor vehicle crashes involving drivers who are drowsy, sleepy, asleep, or fatigued.
Denominator
Total vehicle miles traveled.
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were not available for this objective. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline.
Methodology
Methodology notes
CRSS data are from a nationally representative sample of police-reported motor vehicle crashes. To be included, the crash must involve a motor vehicle traveling on a traffic way and result in property damage, injury, or death.
History
Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective SH-2 in that the data source for objective SH-2 was the National Automotive Sampling System (NASS) General Estimates System (GES), while the data source for this objective is the Crash Report Sampling System (CRSS). CRSS data are not comparable to data from the NASS-GES.
