Filter by Keyword41 report(s) found with simulation in the keywords field 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... In several states, bridge deck delamination of reinforced concrete bridge decks built with partial depth precast concrete panels and cast-in-place concrete has been observed. The partial depth precast concrete panels are typically prestressed. Recently, one such failure was observed in Utah. There is... The research project produces a statewide airspace network, delivery schedule, and truck/drone fleet mix. Such an airspace network is optimized to ensure that drones are strategically deconflicted as required by NASA and the total energy over that day is minimized. Such an airspace network is realized... In an ever-evolving world characterized by environmental challenges and technological advancements, the confluence of natural disasters, particularly increasing wildfire threats, and the role of connected and autonomous vehicles (CAVs) stands as a critical focal point for research and innovation. This... During the past few decades, ramp metering control has been widely implemented in many U.S. states, including Utah. Numerous studies and applications have demonstrated that ramp metering control is an effective strategy to reduce overall freeway congestion by managing the amount of traffic entering the... Connected and automated vehicle (CAV) driving features can impact traffic safety in many aspects owing to their improved driving behavior. On the other hand, road geometric design elements are mainly based on human reactions and behavior, which might affect safety depending on road layout and the parties... This study evaluates two versions of the new super diverging diamond interchange (Super DDI) design as a possible alternative to improve the performance of failing service interchanges in the Denver, Colorado, metro. Three interchanges, Interstate 225 and Mississippi Ave, Interstate 25 and 120th Ave... Urban traffic networks consisting of partially blocked roads often need to remain open to traffic before, during, and after disasters because of their vital roles to hazard preparation, emergency response, and recovery of urban communities. Conducting effective traffic planning of disrupted transportation... Green stormwater infrastructure (GSI) is increasingly used to reduce stormwater input to the subsurface stormwater network. This work investigated how GSI interacts with surface runoff and stormwater structures to affect the spatial extent and distribution of roadway flooding and subsequent effects on... Hydrologic analyses are used for dam safety evaluations to determine the flow a dam must pass without failing. They are also used to evaluate bridge and culvert designs. Many current guidelines model flood runoff solely by an infiltration-excess mechanism. Saturation-excess runoff and subsurface stormflow... |
