Freight transportation places substantial and growing stress on roads and bridges, particularly in rural and regional areas where heavy trucks travel long distances to serve dispersed communities. At the same time, progress in advanced air mobility (AAM) to use new aircraft technologies for cargo transport...
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...
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...
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...
This report is the response to the North Dakota Legislature's request for a study of the transportation infrastructure needs of all counties, townships and tribes in the state. In 2019, the North Dakota Legislature advanced HB 1066 which had a provision for funding distributions to non-oil producing...
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...
This report summarizes Phase II of an ongoing regional effort to expand traffic data collection by leveraging existing transportation infrastructure rather than requiring new data collection equipment. Building on a 2019 pilot project, Phase II, initiated in early 2023, continued the collaboration among...
Despite the ADA’s passage in 1990, non-compliant pedestrian infrastructure remains widespread, often due to the lack of comprehensive pedestrian infrastructure data. Traditional methods of measuring compliance are time consuming, prompting the need for more efficient approaches. This research explores...
A community is considered walkable if it is easy and safe for pedestrians to walk for recreation and exercise and to destinations such as schools, stores, parks, and post offices. A walkable community encourages the safe use of existing infrastructure while expanding transportation options for users...
The transportation experiences of people with disabilities have improved since the passing of the Americans with Disabilities Act (ADA) in 1990. Despite progress, many aspects of the current transportation system still limit people with disabilities from traveling safely and efficiently. Moreover, transportation...
