For more than 20 years speeding has been involved in about one-third of all motor vehicle fatalities (NCSA, 2014, 2023). Even as new vehicle technologies improve driver and passenger safety, a driver’s propensity to drive too fast for the road conditions or more than the speed limit often has tragic consequences. The 2022-2023 National Survey […]

The use of NDE and structural monitoring (SM) technologies for assessing bridge deck condition is becoming increasingly popular due to cost savings and extended service life from timely interventions. Traditional assessment relies on visual and sounding surveys, but NDE methods, such as those based on physical principles of stress-wave propagation, electromagnetic properties, and electrochemical and […]

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 […]

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 […]
