MPC Research Reports
Filter by Keyword25 report(s) found with impacts in the keywords field 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 is Phase II of a previous MPC research project (MPC 02-136) that developed a computer model using a transient, two-dimensional finite volume approach to mathematically describe the thermal response of asphalt pavements due to thermal environmental conditions on an hourly basis. The main objective... This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly... Partial deregulation of the railroad industry substantially eased regulatory impediments to consolidation. Since partial deregulation, there has been a massive consolidation of firms in the railroad industry, which has been premised on efficiency gains, network rationalization, and service quality. In... North Dakota's grain producers rely on an efficient rail system to move their products to export and domestic markets. A recent shift to larger grain hopper cars may threaten the viability of the state's light-density branch line network. This study simulates the impacts of handling larger rail cars... This report contains a brief description of Intelligent Transportation Systems (ITS) and ITS technologies for Commercial Vehicle Operations (ITS/CVO). Second, it discusses previous literature regarding benefits of ITS/CVO for motor carriers, as well as managing the change due to technology. In addition... This research considers the influence of different construction materials on the dynamic impact factor of bridges. The general concept of the dynamic impact factor and typical evaluation methods are reviewed. This study examines the impacts that railroad and trucking deregulation had on rail labor earnings and employment. Soils are an important component of any transportation structure. To improve the engineering properties of these soils, compaction requirements are included in virtually all transportation construction specifications. Field observations indicate however, that soils at near-freezing temperatures may require... This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures... |
