Research Reports
View AllDespite the retirement of transit managers in small urban and rural communities, succession planning to prepare local transit agencies is lacking. Applied research must be developed to provide a smooth transition for the public transportation industry as it moves forward. Current specific workforce shortages... As a result of the considerable differences in mass between vehicles and trains, crashes at highway-rail grade crossings (HRGCs) often result in severe injuries and fatalities. Therefore, HRGC safety is considered a crucial transportation safety issue. Transportation decision makers and agencies need... This report describes the research efforts aimed at determining the repeatability of the IDEAL-CT test for use as part of the balanced asphalt mix design process. Three mixes in common production in northern Utah were investigated by three different labs experienced in performance testing. Within-lab... A community is considered walkable if it is easy as well as safe for pedestrians to walk for recreation, exercise, and to school, stores, parks, the post office, etc. Additionally, a walkable community encourages safe use of existing infrastructure while expanding transportation options for users with... Bridge scour evaluations are often performed using streamflow estimates from regional regression relationships. This approach relies on the accuracy of the relationships and does not consider the effects of flow variations. Alternatively, a complete hydrograph can be obtained from a watershed model and... Shared-use mobility services such as ridesourcing, bikesharing, and carsharing have been introduced in a few rural communities and a fair number of small-urban communities. Input about the interest and potential willingness to use these services, and adoption of various emerging vehicle technologies... This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This series began with the analysis of 1956-57 data and was published in Agricultural Economics Reports 15, 17, 44, 56, and 86 and Agricultural Experiment Station... The first part of the study presents the time-dependent interfacial behavior of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips bonded to a concrete substrate using inorganic resins. Four types of bonding agents (mortar, polyester-silica, ultra-high performance concrete (UHPC)... The Office of Highway Policy Information of Federal Highway Administration (FHWA) publishes statistical data about motor vehicle registrations reported by the 50 states and District of Columbia. According to its 2020 publication, the 97.94% of vehicles in the State of North Dakota are registered as either... This project presents a comprehensive study on enhancing snowplowing routes in 12 regions in northern Utah. The research employs both exact and approximate methods to identify snowplowing routes that lead to reductions in total travel time, turnaround time, and deadhead miles by an average of 4.87%... |
