From the notice

The National Highway Traffic Safety Administration (NHTSA) maintains Countermeasures That Work, an evidence-based reference guide used by State Highway Safety Offices (SHSOs) and other stakeholders to identify effective behavioral traffic safety countermeasures. NHTSA is seeking contractor support to update the guide based on the latest available research, emerging countermeasures, and developments in highway safety. The purpose of this requirement is to update the current 12th edition of Countermeasures That Work and its electronic version (E-CMTW), resulting in the 13th edition. The contractor will conduct comprehensive literature searches, review and evaluate relevant research, and incorporate significant new findings, resources, and implementation considerations into approximately three to four program-area chapters annually. The final deliverable will include a consolidated Word document incorporating all updates made during the period of performance.
