Upper Great Plains Transportation Institute’s Advanced Traffic Analysis Center (ATAC), with support from the North Dakota Department of Transportation (NDDOT) had previously completed a pilot traffic data collection project for two of the state highway intersections located within the City of Minot...
Regular inspection of transportation assets is essential to ensure pavement markings and pavements remain in good, clean, and safe condition. Our previous MPC-funded project (Report No. MPC-668) demonstrated the strong potential of using artificial intelligence (AI) and mobile phone imagery to identify...
Existing bridge deterioration models rely on subjective national bridge inventory (NBI) condition ratings from visual inspections, which lack the objective assessments needed for informed repair and maintenance decisions. Non-destructive evaluation (NDE) tests, such as impact echo (IE), provide quantitative...
In recent years, transportation agencies have increasingly turned to machine learning (ML) to enhance the effectiveness of infrastructure asset management. However, limited local inventory data often hinders building accurate and reliable ML models. Additionally, data privacy and ownership concerns discourage...
The Central Dakota Metropolitan Planning Organization (MPO), which includes the cities of Minot, Surrey, and Burlington, has been developing a Travel Demand Model (TDM) to incorporate new data, reflect current travel patterns, and integrate advancements in transportation modeling techniques. The updated...
Maintaining sufficient charge during the duration of travel along with the time required to recharge the vehicle are major concerns for electric vehicle (EV) owners. This project focuses on in-motion, inductive power transfer (IPT) embedded in roadways to ensure charge duration and replace stationary...
Zero-group velocity (ZGV) modes in rails are studied through simulation and experiments. Local resonances associated with ZGV modes appear as distinct, sharp peaks in the frequency amplitude spectrum, whose resonant frequencies can serve as indicators of the local structural integrity condition of the...
This report describes methods that allow for assessing structural integrity using a direct porting of imaging methods captured by both hand-held and uncrewed aircraft system (UAS)-assisted photography into computational analysis tools to monitor structural degradation of transportation structures. Of...
A theoretical framework is developed for applying the material point method (MPM) to problems of modeling natural hazard effects on several representative geometries. Following an outline of the general methodology, in which the structural system is replaced by a combination of integrated Lagrangian...
The preservation of road safety in snowy regions during the winter season is of paramount significance due to the presence of perilous meteorological circumstances, such as snowstorms, which can result in escalated vehicular collisions and subsequent roadway closure. In the present investigation, our...
