This report describes research that seeks to understand why drivers do not always follow Slow Down, Move Over laws. It also seeks to identify promising approaches to increase safe driving behavior and compliance with these important laws, for the safety of all road users. This report should be of interest to federal, state, and local […]
TRB’s Transit Cooperative Research Program (TCRP) Report 164: Community Tools to Improve Transportation Options for Veterans, Military Service Members, and Their Families explores ways to enhance transportation options for veterans, military service members, and their families by building on the concepts of transportation coordination and mobility management. The report provides guidance and tools to assess […]
Road debris presents a significant threat to traffic safety. It can contribute to crashes directly when vehicles are struck by objects actively falling or strike debris lying on the road. It can also contribute to crashes indirectly, when drivers crash while performing sudden evasive maneuvers to attempt to avoid debris. However, research on the danger […]

NCHRP Research Report 1148: Human Factors Guidelines for Road Systems, Third Edition, from TRB’s National Cooperative Highway Research Program, presents updated guidelines for integrating human factors (HF) principles into the planning, design, construction, and operation of roadway systems. The guidelines build on previous editions of Human Factors Guidelines for Road Systems. Human Factors Guidelines for […]
While it is important for older adults to maintain their mobility, age-related functional declines can impact driving abilities, with important implications for road safety. To better understand factors influencing the safe mobility of older adults AAAFTS commissioned the Longitudinal Research on Aging Drivers (LongROAD) study, a multisite prospective cohort study designed to generate empirical data […]
This tool, from GHSA and State Farm®, helps State Highway Safety Offices (SHSO) more effectively partner with community leaders, Child Passenger Safety Technicians (CPSTs) and others working to protect kids in motor vehicles. With support from State Highway Safety Offices (SHSOs), 40,000 nationally certified Child Passenger Safety Technicians provide free education and car seat inspections […]
This study employed a comprehensive, phased, mixed-methods approach. First, the research team documented state Slow Down, Move Over laws and surveyed and interviewed traffic safety stakeholders from State Highway Safety Offices, Departments of Transportation, and law enforcement agencies to gather information about public information and education and enforcement efforts. Next, the research team conducted focus […]
Derailment loads in nearly all U.S. transit design criteria documents are similar across agencies. However, it is unclear whether horizontal and vertical derailment loads for the efficient and safe design of transit structures are reasonably accurate. Determination of Actual Derailment Loads on Transit Bridges
State departments of transportation (DOTs) have increased their focus on resilience initiatives to address impacts from short-term and long-term stressors such as extreme weather events, wildfires, and flooding. Economic shifts, changes in population, and other disruptions also cause transportation agencies to modify their practices to accommodate uncertainty. State DOTs need tools and approaches to justify […]
