Filter by Keyword43 report(s) found with simulation in the keywords field In recent years, Bus Rapid Transit (BRT) systems have been gaining increasing popularity because of their effectiveness in improving urban mobility. The Utah Transit Authority (UTA) is the primary public transit provider in Salt Lake City and has implemented a 10.8-mile BRT route along 3500/3300 South... Ductile fracture has been identified as the predominant mode of failure for structural elements under extreme loads and the prediction of such represents considerable challenges. Until recently, ductile fracture of metals has been recognized to be dependent on both stress triaxiality and Lode angle parameter.... The American population continues to mature with an impending "aging tsunami" just a few years away. It is projected that by 2050, the number of Americans 65 years old or older will increase to more than 83 million, nearly double its current population of 43 million (U.S. Census 2014). Public transportation... Local transportation agencies in the Salt Lake City (SLC) Metropolitan Area spent more than a decade working toward building a sustainable regional transportation system. Light Rail Transit (LRT) is an integral part of that system. Currently, three LRT lines operate along the Wasatch Front area. A new... Traffic congestion mitigation is one of the key challenges that transportation planners and operations engineers face when planning for construction and maintenance activities. There is a wide variety of approaches and methods that address work zone impacts, starting with simple equations, over spreadsheets... The objective of this project is to find effective configurations for using buckling restrained braces (BRBs) in both skewed and curved bridges for reducing the effects of strong earthquakes. Verification is performed by numerical simulation using analytical models of existing bridges when BRBs are implemented... This report presents a two-phase research program studying i) the interfacial response of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips embedded along a concrete substrate at elevated temperatures and ii) the behavior of NSM CFRP strips for strengthening concrete members subjected... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... Bus Rapid Transit (BRT) is becoming one of the most popular transit services in the United States. BRT is a viable option for many cities and can offer commuters travel times comparable to those experienced in private cars. With about 100 miles of BRT service scheduled for deployment in future years... This report describes the University of Utah Traffic Lab (UTL) driving simulator, and a scenario development for Flex Lanes driving simulation. The first part describes the driving simulator in details. At the time of installation, the UTL driving simulator was unique and the first to join microsimulation... |
