PURPOSE
The Federal Highway Administration (FHWA) collects and publishes annual state-based counts of licensed drivers, which have been used to estimate per-driver crash rates and document a decline in young licensed drivers. The accuracy of these data has been questioned.
METHODS
We compared the number of young licensed drivers as reported by the FHWA (2006-2012) with that generated directly from New Jersey (NJ) administrative licensing data. Census data were used to estimate the proportion of NJ adolescents who were licensed.
RESULTS
FHWA data showed a decline in the proportion of licensed 17- to 20-year olds over the 7-year period (77%-63%), whereas analysis of NJ licensing data revealed a more stable trend (75%-74%).
CONCLUSIONS
We advise against use of FHWA licensing data for research purposes and encourage FHWA to work with state licensing agencies to review and enhance data collection and quality control procedures with the goal of ensuring the accuracy of licensing data.
目的
美国联邦公路管理局（FHWA）收集并公布基于各州的年度持证驾驶员数量，这些数据已被用于估计每驾驶员的撞车率，并记录年轻持证驾驶员数量的下降情况。这些数据的准确性受到了质疑。
方法
我们将FHWA报告的年轻持证驾驶员数量（2006 - 2012年）与直接从新泽西州（NJ）行政许可数据生成的数量进行了比较。人口普查数据用于估计NJ获得驾照的青少年比例。
结果
FHWA数据显示，在这7年期间，17至20岁持证者的比例有所下降（从77%降至63%），而对NJ许可数据的分析显示出更稳定的趋势（75% - 74%）。
结论
我们建议不要将FHWA许可数据用于研究目的，并鼓励FHWA与各州许可机构合作，审查并加强数据收集和质量控制程序，以确保许可数据的准确性。
