TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 523: Integration of Roadway Safety Data from State and Local Sources documents the ways in which transportation agencies are collaborating with local agencies to integrate and maintain data. This information can help inform how transportation agencies approach the challenge of facilitating access to and integrating data from a multitude of information systems from external sources. Accompanying the report are the following appendices:

  • Appendix A: Summary of Published State DOT Case Studies. Appendix A summarizes the literature review findings related to existing or planned state DOT efforts to integrate roadway safety data.
  • Appendix B: Survey Questions and Results. Appendix B includes the survey questions and the results for each question.
  • Appendix C: List of Interviewees. Appendix C lists the agency or organization representatives who contributed to the development of this synthesis.
  • Appendix D: Sample Documents That Illustrate Practices Related to State and Local Roadway Data Integration. Appendix D presents sample documents that were offered by agencies and are relevant to the study.
  • Appendix E: Links to Resources Identified. Appendix E includes links to resources identified through the literature review or shared by the agencies interviewed.
