MPC Research Reports
View AllThis research compares safety, measured by expected crash frequency and severity, on road segments where design exceptions were approved and constructed to similar road segments where no design exceptions were approved or constructed. Data were collected for design exceptions in Utah in the years 2001... 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... The main objective of rural roadway pricing is revenue generation, rather than elimination of congestion externalities. This report presents a model that provides optimum tolls accounting for pavement deterioration and economic impacts. This model contains multiple components, because imposing tolls... This report details the outcomes of shear spiking two open-deck, timber trestle railroad bridges and examining the effectiveness under applied loading. The bridges were made available to the researchers by the Union Pacific Railroad and were located in their Southern Region. The first site was located... SAFETEA-LU contains language indicating that State Department of Transportation (DOTs) will be required to address safety on local and rural roads. It is important for state, county, and city officials to cooperate in producing a comprehensive safety plan to improve statewide safety. This legislation... This report presents an analysis of freeway incidents on the Salt Lake Valley freeway network. Different types of incidents at the most common/difficult locations are analyzed through traffic microsimulation using VISSIM simulation software. The analysis focuses on incident induced freeway delays, but... This study analyzes economies of scale and density as a rationale for subsidizing transit agencies in small urban areas. A long-run cost model is estimated using data from 2006 to 2009 for 168 transit agencies that directly operated fixed-route bus service in small urban areas. Using vehicle revenue... PTV Traffic Platform (Sep 2011, MPC-10-229E) This report presents an overview of the PTV TrafficPlatform software, which is designed as a tool to help in the training process of traffic operations center (TOC) operators. TrafficPlatform is based on an integration of VISSIM microsimulation, VISUM macrosimulation, SQL database, and a user-friendly... An attempt is made to integrally evaluate the safety of large trucks on mountainous highways. The I-70 corridor in Colorado is chosen to demonstrate the methodology because of its typical mountainous terrain and adverse weather conditions. First, the ten-year historical accident records are analyzed... The objective of this research is to investigate the injury severity of truck drivers by studying MV and SV accidents involving trucks on rural highways separately. By using multinomial logit models, the complex interactions between roadway characteristics, driver characteristics, accident characteristics... |
