Transportation Research Board (TRB):National Cooperative Highway Research Program (NCHRP)

TRB Reports

  • Assessment of Characteristics of State Data Linkage Systems. State systems that integrate data by linking police crash reports to medical records provide important information that can be used to better understand motor vehicle crash injuries. The objective of this study was to better understand the facilitators and barriers to successful data linkage systems. The report is available here.
  • CODES Program Transition and Promising Practices: The Crash Outcome Data Evaluation System (CODES) is a State-based program originally developed in 1992 by the National Highway Traffic Safety Administration under NHTSA’s National Center for Statistics and Analysis. CODES uses a statistical linkage process known as probabilistic linkage to combine information from motor vehicle crash reports and hospital records, sometimes also adding databases from sources such as emergency medical services (EMS), death certificate, and others. CODES originally operated through cooperative agreements between NHTSA and grantees in member States. In 2013, NHTSA transitioned the CODES programs to full State-level responsibility. This report summarizes the history of CODES, relates the transition plan, and describes CODES-related projects and output from 2009 to 2014, including a compilation of abstracted State-specific linked data applications.
  • Dynamic Mobility Application Policy Analysis: Policy and Institutional Issues for Response, Emergency Staging and Communications, Uniform Management, and Evacuation (R.E.S.C.U.M.E.). The U.S. Office of the Assistant Secretary for Research and Technology on Aug. 11, 2015, released a report that documents policy considerations for mobility applications that use connected vehicle data sets to provide first-responders, emergency management centers, and road crews enhanced information for responding to incidents and emergencies.


The NCHRP reports below are those related to Emergency Medical Services. A complete listing of NCHRP reports is available here.

  • NCHRP 17-57 [Active] Development of a Comprehensive Approach for Serious Traffic Crash Injury Measurement and Reporting Systems. Research is currently underway. The project's fourth interim report was submitted in August 2014, and panel comments were forwarded to the research team. A continuation ending December 2016 has been initiated. See interim information.
  • NCHRP 20-24(37)K Measuring Performance among State DOTs: Sharing Good Practices - Safety (Serious Injuries). The objectives of this project were to (a) review and assess states’ current practices for quantifying serious injuries from motor vehicle crashes, (b) describe issues to be addressed in adapting CODES or other available databases to provide a basis for comparative analysis of DOT performance regarding serious crash injuries and safety management, and (c) describe feasible options for addressing these issues and assess their relative merits. NASEMSO Executive Director Dia Gainor served on the panel overseeing the project. The report is available here.
  • The NCHRP 20-7 (321) report, "A Framework for Collecting Emergency Responder/Roadside Worker Struck-by/Near-Miss Data," reflects an effort to design a uniform system for collecting vital information on emergency responders and other roadway workers who become a casualty (or nearly so) while performing their duties. NASEMSO was represented by Mary Hedges and Stuart Castle (NM EMS Data Manager) on the panel overseeing the project. The report is available here.
  • The NCHRP 20-05 (43-15) Synthesis, "Emergency Medical Services Response to Motor Vehicle Crashes in Rural Areas" gathered and analyzed information from 14 rural states on successful practices leading to timely emergency medical response. NASEMSO members on the panel included James DeTienne (MT), Dean Cole (NE), and Dia Gainor (ID). The report is available here.
