Dynamic message signs provide key information for drivers. Researchers at South Dakota State University tested new signs that are constructed using adhesives rather than welding to assure that the signs will stand up the rigors of roadside use.
Researchers at the University of Wyoming are developing tools that local road agencies can use to assess the condition of rural gravel roads. Those user-friendly tools implement smartphones, machine learning, and optimization techniques to help local road managers identify the most appropriate treatment type for each road based on service level, estimated project costs, predicted road conditions, and whether or not to fund a project.
With targeted education related to the accessibility, familiarity, and incentives related to ridesourcing, research at North Dakota State University indicates this mobility option could become a viable impaired driving prevention strategy in rural communities.
Colorado State University researchers have developed a process to streamline bridge inspections and make them more objective and quantitative. Their method could keep better tabs on deteriorating infrastructure and help bridge owners plan for maintenance.
