View AllThis study developed a number of models to estimate the relationships between land use, transit ridership, household expenditures, and municipal spending, with a focus on small urban areas. First, a regression model was developed that estimated transit ridership in small urban areas as a function of... The existing online mapping systems process many user route queries simultaneously, yet solve each independently, using typical route guidance solutions. These route recommendations are presented as optimal, but often this is not truly the case, due to the effects of competition users experience over... Reinforced concrete bridge wall piers constructed using older codes perform inadequately during strong earthquakes; deficiencies include short reinforcement lap splices, insufficient steel reinforcement ratios in the longitudinal and transverse direction, and inadequate seismic detailing. Three half-scale... While the automobile industry is rapidly transitioning towards automation, the transit industry in the United States has recently begun investigating automation in transit operations. Multiple U.S. transit agencies have been experimenting with various automation technologies in transit vehicles. Examples... In Wyoming, most county paved roads were built decades ago without following minimum design standards. However, the recent increase in industrial/mineral activities in the state requires developing an efficient pavement management system (PMS) for local paved roads. The new PMS which is currently being... Fourteen Thin Lift Treatments (TLTs) in Utah's Department of Transportation (UDOT) Region 2 were evaluated over a five-year period in order to assess their performance. Surface distress data was quantified using Pavement Condition Indices (PCIs), and Remaining Service Life (RSL) were estimated following... 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 crashes resulting in death, injury, and property damage continue to take place due to preventable factors. Among states, North... This report presents a research program studying the grooved bonding schemes of composite sheets (carbon fiber reinforced polymer, CFRP) for rehabilitating concrete members. The first phase of the research presents the efficacy of functional periodicity on controlling the occurrence of interfacial failure... An evaluation of the ability of the BBR (Bending Beam Rheometer) as a test to determine changes in the low temperature properties of asphalt mixture parameters was conducted, along with the possible implications of adopting this test for low temperature pavement performance. It was found that the creep... Tribal communities recognize the need to improve roadway safety. A five-step methodology has been developed by the Wyoming Technology Transfer Center (WYT2/LTAP) to improve roadway safety on reservations. This methodology was initially implemented on the Wind River Indian Reservation (WRIR), which led... |
