Relative to passenger cars, two- and three-wheeled vehicles such as motorcycles, mopeds, and seated motor scooters (50cc or less) are associated with a higher risk for fatalities and serious injuries in the event of a traffic crash, as they do not offer the protection of an enclosed vehicle or include other safety enhancement features such as occupant restraints. BTSCRP Research Report 11: Improvi...

The National Highway Traffic Safety Administration defines high-visibility enforcement (HVE) as a universal traffic safety approach designed to create deterrence and change unlawful traffic behaviors. HVE combines highly visible and proactive law enforcement targeting a specific traffic safety issue. Law enforcement efforts are combined with visibility elements and a publicity strategy to educate ...

Since their introduction in the United States in 2017, the use of electric scooters (e-scooters) has expanded to the streets and sidewalks of many cities, and all indicators point to continued growth. BTSCRP Research Report 9: E-Scooter Safety Toolbox , from TRB's Behavioral Traffic Safety Cooperative Research Program, presents findings from a multiyear research effort that sought to build on exis...

Roadway fatalities and serious injuries are a significant public health concern in rural and tribal settings. Creating a coalition of interested individuals is part of the Safe System Approach that addresses the high rates of these fatalities and serious injuries. BTSCRP Research Report 8: Highway Safety Behavioral Strategies for Rural and Tribal Areas: A Guide , from TRB's Behavioral Transportati...

State highway safety offices (SHSOs) manage behavioral traffic safety programs at the state level. At the regional level, metropolitan planning organizations (MPOs) develop safety performance measures and targets. BTSCRP Research Report 7: Improving MPO and SHSO Coordination on Behavioral Traffic Safety: Guide and Toolkit , from TRB's Behavioral Traffic Safety Cooperative Research Program, present...

Child restraint systems (CRS) requirements for children in rideshare vehicles vary by state and city. In 43 states, child passengers in rideshare vehicles are required to be secured in appropriate CRS. However, 28 states exempt taxis from the CRS requirement.

The large number of baby boomers, who are likely to drive much longer than previous generations, points to an increased need for older-driver safety programs and policies. As state-level agencies charged with providing information and programs on behavioral traffic safety, state highway safety offices (SHSOs) are a logical place for either developing and managing a more extensive older-driver safe...

Changeable, electronic, or dynamic message signs are used to provide real-time traffic information to drivers while en route to their destination. Many agencies also use these signs to display safety messages when the signs are not being used to display other traffic information. These types of messages encourage safe driving behaviors such as wearing seat belts and not drinking and driving. The T...

Quickly advancing automated driving system (ADS) technologies are expected to positively affect transportation safety. ADS includes a plethora of applications that affect safety, mobility, human factors, and environmental aspects of driving. TRB's joint publication of the National Cooperative Highway Research Program and the Behavioral Transportation Safety Cooperative Research Program is titled&n...

Distracted driving is a complex and ever-increasing risk to public safety on roadways. Drivers’ use of electronic devices significantly diverts human attention resources away from the driving task. The enforcement community faces significant challenges as electronic device use has expanded beyond simply texting or talking. Legislation regulating electronic device use while driving is inconsistent ...
