Thank you to those who attended, presented, and assisted in the planning of the 2024 Southeast CMV Safety Research Summit. The Summit brought together government, industry, universities, law enforcement, and non-profits to form meaningful partnerships. Visit the recap page here.
A past research effort initiated by the Federal Highway Administration (FHWA) found that the combined workload of guidance (i.e., selection of the vehicle path) and control (i.e., physical operation of the vehicle) in the vicinity of interchanges creates a particularly challenging environment for motorists (Katz et al. 2018). At interchange ramp locations, drivers use cues […]

It follows that these features can change drivers’ roles, including adopting passive […]
This report is an introduction to behavioral traffic safety countermeasures for rural stakeholders who want to build capacity, form partnerships, and address problems in their communities, based on NHTSA’s 11th edition of Countermeasures That Work. This new report features select speed, alcohol-impaired driving, and occupant protection countermeasures relevant to rural communities. It is not intended […]
After a brief reduction during the initial months of the COVID-19 pandemic, traffic fatalities in the United States surged to the highest levels in many years. Initially experts hypothesized that the increase was due in large part to reduced traffic volumes facilitating speeding. However, traffic fatality rates remained elevated throughout 2021 and 2022, despite traffic […]
Passenger vehicles are defined as motor vehicles with gross vehicle weight ratings of 10,000 pounds or less and include passenger cars and light trucks (SUVs, pickups, vans, and other light trucks). In 2022 there were 25,420 passenger vehicle occupants who died in motor vehicle traffic crashes, a 4-percent decrease from 26,465 in 2021. An estimated […]
Speeding has contributed to thousands of fatalities in the Unites States annually for decades, despite long-standing awareness of its risks. Intelligence speed assistance (ISA) is a technology designed for speed limit compliance that has been shown to reduce speeding, and European law has mandated ISA for all new vehicles sold from July 2024. The United […]
