Research Reports Filter by Keyword16 report(s) found with land in the keywords field A theoretical framework is developed for applying the material point method (MPM) to problems of modeling natural hazard effects on several representative geometries. Following an outline of the general methodology, in which the structural system is replaced by a combination of integrated Lagrangian... Precipitation-induced landslides pose risks to humans through property damage, disruption of infrastructure, injury, and loss of life. These risks may be altered by climate change, as changes in vegetation cover and associated root cohesion might lead to a change in areas susceptible to landslides. We... Longitudinal joints in Portland Cement Concrete (PCC) pavement slabs require tie (dowel) bars to control joint opening resulting from thermal stresses. Inspections of PCC pavements by the South Dakota Department of Transportation using ground penetrating radar revealed that it is common for tie bars... This study developed a number of models to estimate the relationships between land use, transit ridership, household expenditures, and municipal spending, with a focus on small urban areas. First, a regression model was developed that estimated transit ridership in small urban areas as a function of... Transportation systems generate certain health-promoting benefits such as access to social, economic, and cultural resources, but they also are a source of air pollution, noise, safety hazards, and barriers that diminish social cohesion in neighborhoods. Streets, in particular, are among the most important... Not long after the advent of cars arose a conflict between moving traffic and residential livability. The typical response pushed traffic off residential streets and onto nearby arterial roads. With many researchers identifying traffic on residential streets as an underlying issue behind poor livability... 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... Small urban sprawl has resulted in new housing developments and business centers that have never been served by transit. Unfortunately, transit agencies are often not included in the land development process within small urban communities. The objectives of this study were to determine what steps small... The low mobility of seniors may be due in part to a history of auto-oriented transportation and land use policy decisions. More recently, land use policies that make it possible to drive less show promise of effectiveness for the population as a whole. However, little attention has been paid to the implications... In this paper, elevator trip generation equations are estimated from detailed facility, land-use, and highway traffic data in North Dakota. A trip attraction equation is used to explain the effects of elevator storage capacity and side track capacity on elevator throughput. Elevators are classified on...
