Filter by Keyword23 report(s) found with environment in the keywords field The First Mile Last Mile (FMLM) challenge garners significant attention as a means to assess the accessibility of the first leg to transit and the last leg from public transit. As a critical barrier to public transit accessibility, the challenge provides many opportunities to closely analyze conditions... 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... 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... Numerous studies have found that suburban residents drive more and walk less than residents in traditional neighborhoods. What is less well understood is the extent to which the observed patterns of travel behavior can be attributed to the residential built environment itself, as opposed to the prior... 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... Transportation is a vital national need and one of the areas of increased employment opportunities. Fostering student interest in transportation and transportation related areas of study is vital to our nation's future work force, and these arenas are rapidly becoming a popular career choice for undergraduate... 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... The study examined organizational issues that affected employee motivation and retention. To obtain information about these issues that could be qualitatively analyzed and compared from state to state, face-to-face interviews were conducted with two or three individuals at the Minnesota, Iowa, North... 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... This paper reports the results of a survey designed to determine the issues affecting North Dakota's rural aviation community. The survey elicited responses from airport managers on the broader concerns of aviation in the state. |
