Filter by Keyword204 report(s) found with analysis in the keywords field A numerical model simulating the seismic behavior of precast concrete columns confined with glass fiber reinforced polymer (GFRP) spirals and longitudinally reinforced with steel or a combination of steel and GFRP bars was developed using the Open System for Earthquake Engineering Simulation (OpenSees).... 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... 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 I-15 Downhole Array (I15DA) is located near the intersection of I-15 and I-80 in Salt Lake City, Utah. This downhole array is installed in soft soil deposited by Lake Bonneville, where depth to bedrock is expected to be at a considerable depth. The soil conditions at the I15DA are representative... Roadside safety is a critical aspect of transportation management, with elements like rigid obstacles, guardrails, clear zones, and side slopes significantly impacting accident outcomes. The Federal Highway Administration (FHWA) provides a valuable rating system for departments of transportation (DOTs)... The purpose of this research project was to investigate and determine the reasons for premature deterioration of the geogrid-reinforced pavement system on the section of SR-10 between Muddy Creek and Emery, Utah.
The statistical analyses and evaluations indicate that the structural design of the primary... The objective of this research is to compare the level of public transportation services provided in North Dakota to those of surrounding states. The study focuses on North Dakota, South Dakota, Montana, Wyoming, Nebraska (excluding the Omaha metro area), and Minnesota (excluding the Twin Cities metro... According to the 2017 ASCE Infrastructure Report Card (ASCE 2017), 9.1% of the U.S. bridges are structurally deficient. The majority of deficient bridges are in service on low-traffic volume roads, and these bridges should be replaced or repaired for public safety in a timely manner. As an alternative... 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 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%... |
