Changeable message signs (CMSs) serve as safe, accessible sources of relevant travel information. Previous research has provided insight into the potential value of CMSs as sources of traveler information. However, a gap remains in efforts to document the information and the messaging that effectively promote desired changes in traveler behavior to improve safety and the […]
There was a small decline in motor vehicle crash fatalities in the United States in 2023 relative to 2022. However, each death represents an unacceptable human, societal, and economic cost. While causes of motor vehicle fatalities are complex, risky driving behaviors such as speeding, alcohol involvement, and non-seat belt use are linked to tens of […]
The evolving landscape of climate conditions leads to more frequent and intense natural hazard events, affecting low-volume roads on federal lands. Despite the existence of known maintenance solutions to reduce these impacts, the limited funding availability hinders the implementation of these solutions at scale. This funding limitation is compounded by the absence of necessary data […]

The safety of roadside responders is often placed in jeopardy by the potential dangers posed by passing vehicles. To develop and implement effective protection measures for roadside responders, comprehensive safety data is essential. Traditional methods relying on crash data to identify incidents involving roadside responders, such as struck-by or secondary crashes, provide some information about […]
Advanced vehicle technologies have the potential to improve safety and convenience for drivers; however, in order to realize these benefits, it is important that drivers use the systems appropriately. Past research has documented gaps in drivers’ understanding of how new technology works and when it should be used. It follows that the interplay between a […]
Decarbonisation of road transport was until recently considered the most challenging part of the climate agenda. Still the ascent of electric vehicles is making significant advances possible while, at the same time, opening several new complex conundrums: integration of power and transport systems, establishing supply chains of needed materials and conversion of existing industries to […]
An overarching goal of road corridor projects is to reduce traffic delays and improve safety for all users, including drivers, pedestrians, cyclists, and delivery vehicles. Doing so often involves changing the way road users access sites along the road, such as by removing or relocating driveways; adding medians, turning restrictions, service and frontage roads, and […]
Use of DOT-compliant motorcycle helmets was 73.8 percent in 2023, not statistically different at the 0.05 level from 66.5 percent in 2022. The 2023 estimate is the highest ever recorded. The 2023 data collection occurred during the usual timeframe of early June, immediately following the Click It or Ticket campaign. There were 945 motorcyclists observed […]
The emergence of various new forms of urban mobility services in recent years has led to new pressures on curbside space. Municipalities, the entities frequently responsible for managing the curbside, are in many instances handling these growing pressures by reallocating portions of the curbside away from traditional uses (such as metered and residential parking) in […]
