Research Reports
View AllThis 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... The United States lags behind other developed countries in several transportation safety metrics. Progress has been made in reducing the number of traffic-related fatalities, but preventable crashes resulting in death, injury, and property damage continue to occur. The statewide driver survey provides... This study proposes a new remote sensing technique to measure three-component (3C) dynamic displacement of three-dimensional (3D) structures. A sensing system with an unmanned aerial vehicle (UAV) platform and contact-free sensors (e.g., optical and infrared (IR) cameras) was employed to provide a portable... Public education and outreach activities increase the effectiveness of work law enforcement does to prevent large truck-involved crashes. This demonstration project was conducted through two components including a primary education program and a complimentary education program designed to be executed... Escherichia coli (E. coli) is often used as an indicator organism to quantify the microbial safety of natural water resources. E. coli in stormwater runoff can cause serious health risks in natural water bodies. Conventional stormwater best management practices are generally not effective at removing... 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... In recent years, major initiatives have been taken to replace non-renewable materials with environmentally friendly and sustainable ones. The present study was undertaken to apply a scalable process for laboratory production of cellulose nanofibers (CNF) and to evaluate the feasibility of using the produced... Pavements in cold regions of the United States undergo significant accumulation of snow and ice on their surfaces during the extended winter season, leading to reduced skid resistance and increased traffic crashes. Deicers, such as sodium chloride, calcium chloride, and magnesium chloride, have been... 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.... This study examines rural transit needs for Jaunt. The objective is to quantify the need for transit services in each of Jaunt's partner jurisdictions. Jaunt provides transit in the city of Charlottesville, Virginia, and the counties of Albemarle, Buckingham, Fluvanna, Greene, Louisa, and Nelson. Neighboring... |
