Filter by Keyword217 report(s) found with analysis in the keywords field 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... 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... Winter storms significantly increase crash risk and disrupt travel, especially under extreme conditions. Gusty winds, heavy moisture, and low temperatures can quickly make travel dangerous in the Northern Plains. This study was aimed at understanding winter truck crashes, given the prominence of commercial... The Americans with Disabilities Act (1990) mandates that paratransit services should be comparable to fixed-route systems. However, with only 5% of the population utilizing public transit, this comparison does not adequately highlight the disparities between persons with disabilities and those without.... Potholes are a significant pavement distress compromising safety and causing costly damage. They result from pavement deterioration due to aging, weather, and traffic overloads, with the Mountain Plains region particularly affected due to freeze/thaw cycles. Timely identification and repair of potholes... This report discusses the benefits of full-scale pavement testing and the use of accelerated pavement testing (APT) to collect pavement performance data under actual experimental conditions. The report highlights the development and operation of road test tracks, such as the Minnesota Road Research Project... This report presents the behavior of reinforced concrete beams retrofitted with carbon fiber reinforced polymer (CFRP) sheets and ultra-high performance concrete (UHPC) jackets in a multi-hazard environment. Following the procedural protocol of a published standard, the beams are cyclically loaded under... Recently, significant advances have been made in the development of rapid setting cementitious materials for partial-depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed.... An efficient and safe transportation system is essential to communities during the long-term recovery period after earthquakes. A disrupted transportation network due to infrastructure damage or failure affects the functionality of the traffic system and poses increased traffic safety risks. A rational... |
