Filter by Keyword68 report(s) found with roads in the keywords field The purpose of the initial project was to establish a baseline for the evaluation of proposed fatigue mitigation efforts, to demonstrate the utilization of measures of sleep and fatigue, and to gather initial data for comparison to other previous studies. Results demonstrated that there was enough data... Over the last two decades, the use of advanced scientific and data-driven statistical methods has been continuously evolving to reduce the frequency and severity of crashes on our roadways. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) was... Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with... Due to the recent oil boom, the Fort Berthold Reservation has experienced a dramatic increase in highway and local traffic. To support energy transportation and provide safe roads, the reservation needs cost-efficient and effective transportation planning for present and future needs. A quality road... Converse, Goshen, Laramie, and Platte counties were selected in accordance with a legislative directive as part of a project to determine the impact of the oil and gas industry on county infrastructure. This thesis takes into account the impact of county gravel roads and strategies used to help develop... The purpose of this study is to provide information about railroad fuel efficiency that may be useful in evaluating transportation energy policies and assessing the sustainability of potential projects. The specific objectives are to (1) develop railroad energy efficiency models that describe differences... This study addresses both structural and surfacing issues associated with unpaved roads subjected to heavier traffic applications. Different gravel types with various dust suppressants including recycled asphalt pavement (RAP) and soil stabilizers were evaluated in an attempt to provide the best road... 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... 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... As more Recycled Asphalt Pavement (RAP) becomes available to use in roadways, The Wyoming T2/LTAP Center and two Wyoming Counties investigated the use of RAP in gravel roads. The Wyoming DOT and the Mountain-Plains Consortium funded this study. The investigation explored the use RAP as a means of dust... |
