Filter by University60 report(s) found for Utah State University During area-wide episodes of poor air quality, people may reduce their transportation-related emissions by driving less, reducing their exposure to emissions by walking/bicycling less, or going about their lives as usual. These three reactions have different consequences for transportation, health, and... Ultra-high-performance concrete (UHPC) is distinguished by its superior mechanical and durability properties. These characteristics are attained through a precise mixture design that includes a low water-to-cement ratio, high fineness supplementary cementitious materials (SCMs), and steel fibers. This... 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.... With the development of accelerated bridge construction (ABC), the seismic performance of typical ABC column-footing connections has been evaluated in high earthquake-prone states, like Utah, California, Nevada, and Idaho. But to date, the current literature has yet to fully examine the impact behavior... This research project’s objective was to investigate the impacts of transit stop location (near-side versus far-side) on pedestrian safety and traffic operations at intersections. Three different video-based behavioral observation data collections at signals in Utah were utilized and studied: (1) transit... With the popularization of accelerated bridge construction (ABC), the utilization of splice sleeve connections has been researched to determine their performance using a variety of connection details and under several loading scenarios. However, fundamental research on the load distribution and load... Polymer concrete (PC) has found increasing use in construction over the last few decades. One common use of this material is as an overlay material on bridges and highways. This use can be attributed to some advantages of this material such as its high bond strength with substrate concrete, short curing... U.S. residents across many regions continue to face episodes of poor air quality due in part to pollution and emissions from the transportation sector. Strategies to encourage travel behavior changes and reduced driving during such events may or may not be effective. To illuminate how area-wide air pollution... Transportation planning, traffic monitoring, and traffic safety analysis require detailed information about pedestrian volumes, but such data are usually lacking. Fortunately, recent research has demonstrated the accuracy of pedestrian volumes estimated from push-button data contained within high-resolution... This study evaluated connected and autonomous vehicle (CAV) crash reporting practices across the United States, emphasizing the importance of standardized reporting and legislation for the safe deployment of CAVs on public roads. Through a survey of state transportation officials and a review of current... |
