This report responds to a Congressional request for an assessment of the 5.9 Gigahertz (GHz) Dedicated Short Range Communications (DSRC) in accordance with the requirements provided by Congress in the Moving Ahead for Progress in the 21st Century Act ("MAP-21"; P. L. 112-141), Section 53006, codified at 23 U. S. C. 518. The report: provides an assessment of the status of DSRC technology and applications, including known and potential gaps; describes a recommended implementation path; and discusses opportunities to use commercially available communications for Connected Vehicle applications under specific circumstances. The assessment is predominantly derived from U. S Department of Transportation research, analysis, and deployment planning that has been performed in partnership with stakeholders and industry experts over the last decade. The assessment is validated by an independent evaluation provided by the National Research Council (NRC) of the National Academies of Sciences, Engineering, and Medicine, who engaged with third party experts in reaching their conclusions. The NRC Letter Report was delivered to Congress in April 2015 and is included in this report as Appendix J. This report has been revised as needed to respond to each comment in the NRC Letter Report.
