BEHAVIORAL TRAFFIC SAFETY COOPERATIVE RESEARCH PROGRAM Since the widespread introduction of motor vehicles more than a century ago, crashes involving their operation remain a significant public health concern. While there have been enormous improvements in highway design and construction, as well as motor vehicle safety, which have been instrumental in lowering the rate of crashes per mil- lion miles in the United States, more than 35,000 people die every year in motor vehicle crashes. In far too many cases, the root causes of the crashes are the unsafe behaviors of motor vehicle operators, cyclists, and pedestrians. Understanding human behaviors and developing effective countermeasures to unsafe ones is difficult and remains a major weakness in our traffic safety efforts. The Behavioral Traffic Safety Cooperative Research Program (BTSCRP) develops practical solutions to save lives, prevent injuries, and reduce costs of road traffic crashes associated with unsafe behav- iors. BTSCRP is a forum for coordinated and collaborative research efforts. It is managed by the Transportation Research Board (TRB) under the direction and oversight of the Governors Highway Safety Association (GHSA) with funding provided by the National Highway Traffic Safety Administration (NHTSA). Funding for the program was originally established in Moving Ahead for Progress in the 21st Century (MAP-21), Subsection 402(c), which created the National Cooperative Research and Evaluation Program (NCREP). Fixing Americaâs Surface Transportation (FAST) Act continued the program. In 2017, GHSA entered into an agreement with TRB to manage the research activities, with the program name changed to Behavioral Traf- fic Safety Cooperative Research Program. The GHSA Executive Board serves as the governing board for the BTSCRP. The Board consists of officers, representatives of the 10 NHTSA regions, and committee and task force chairs. The Research Committee Chair appoints committee members who recommend projects for funding and provide oversight for the activities of BTSCRP. Its ultimate goal is to oversee a quality research program that is committed to addressing research issues fac- ing State Highway Safety Offices. The Executive Board meets annu- ally to approve research projects. Each selected project is assigned to a panel, appointed by TRB, which provides technical guidance and counsel throughout the life of the project. The majority of panel mem- bers represent the intended users of the research projects and have an important role in helping to implement the results. BTSCRP produces a series of research reports and other products such as guidebooks for practitioners. Primary emphasis is placed on disseminating BTSCRP results to the intended users of the research: State Highway Safety Offices and their constituents.

e National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, non- governmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president. e National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. John L. Anderson is president. e National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president. e three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. e National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

BTSCRP Research Report 4: Promoting Older Driver Safety: Guide for State Practices provides guidance for state highway safety offices (SHSOs) to enhance older driver safety. The research team conducted a survey of SHSOs to determine the degree to which states have implemented NHTSA Highway Safety Program Guideline No. 13, Older Driver Safety; conducted a literature search to identify challenges and effective approaches in the areas of program management, roadway design, driver licensing, communications and outreach, and problem/countermeasure identification; and developed a guide for SHSOs to enhance older driver safety based on Highway Safety Program Guideline No. 13. The guide will be of interest to SHSOs and other stakeholders concerned with improving older driver safety. By 2060, the number of people age 65 and older in the United States is projected to more than double, which will represent nearly one in four people. While older adults tend to practice safe driving behaviors, the effects of aging may impact their driving ability. What makes it difficult for highway safety countermeasures is that there is no specific age when any of these effects occur and to what degree someone can be affected. Aging impacts people differently, but the fact remains that older adults accounted for 18 percent of all fatalities in 2017. In 2014, NHTSA recognized the issue and released Highway Safety Program Guideline No. 13, Older Driver Safety. It stated that states should have a program to reduce older driver crashes, fatalities, and injuries. Each state older driver safety program should address driver licensing and medical review of at-risk drivers, medical and law enforcement education, roadway design, and collaboration with social services and transportation services providers. It is unclear to what extent state highway safety offices are addressing this guideline or preparing to meet the increased challenges of the older driver population in the future. In BTSCRP Project BTS-12, Cambridge Systematics was asked to (1) conduct a survey of SHSOs to determine the degree to which states have implemented Highway Safety Pro- gram Guideline No. 13, Older Driver Safety; (2) conduct a literature search to identify challenges and effective approaches in the areas of program management, roadway design, driver licensing, communications and outreach, and problem/countermeasure identifica- tion; and (3) develop a Guide for SHSOs to enhance older driver safety based on Highway Safety Program Guideline No. 13.
