MPC Research Reports
View AllFor the purpose of this paper, the definition of traffic incident is "any non-recurring event that causes a reduction of roadway capacity or an abnormal increase in demand." This definition will provide the necessary broadness for types of traffic incidents that are going to be addressed here and for... This report is a summary of work performed by the Utah Traffic Lab (UTL) to develop training programs for Utah Department of Transportation (UDOT) Traffic Operations Center (TOC) operators. The report includes training materials that are already in service and those additionally developed, at both basic... This study was initiated to provide assistance to counties that were experiencing considerable impacts to their road systems from oil and gas drilling but were not receiving sufficient revenue to keep up with these impacts. As drilling expanded from Campbell County into Sheridan and Johnson counties... In a previous related study conducted by the University of Wyoming (Phase I), fatigue cracking of traffic signal poles was determined to be related to the average wind speed (Price 2009). However, high-mast data did not indicate the same direct average wind speed fatigue cracking relationship behavior.... The built environment consists of everything humanly made, arranged, or maintained (Bartuska and Young 1994). In relation to travel behavior, there has been a focus on improving our understanding of how the built environment influences one's travel mode choice. Planners need evidence showing how land... There are 16 small to medium simple span bridges in Larimer County that are currently load rated solely based on visual inspections. Most of these bridges are prestressed concrete bridges. The objective of this project is to load rate these bridges using structural analysis with very little to no information... The use of off-specification fly ashes to increase the shear strength and stiffness of an expansive soil-rubber (ESR) mixture is investigated systematically in this study. The off-specification fly ashes used include a high-sulfur content and a high-carbon content fly ash. A class C fly ash is used as... This research focuses on finding a method for creating cost effective and innovative steel bridges in Colorado. The design method that was discovered to create this cost efficiency was designing the beams as simply supported for non-composite dead loads, beam weight and wet concrete, and then making... Two-dimensional, depth-averaged flow models are used to study the distribution of flow around spill-through abutments situated on floodplains in compound channels and rectangular channels (flow on very wide floodplains may be treated as rectangular channels). The study leads to useful insights regarding... Current pavement design based on the AASHTO Design Guide uses an empirical approach from the results of the AASHO Road Test conducted in 1958. To address some of the limitations of the original design guide, AASHTO developed a new guide: Mechanistic Empirical Pavement Design Guide (MEPDG). This guide... |
