Performance Comparison Of A Roundabout Versus Two-Way Stop Controlled (Twsc) Intersections, Deogratias Eustace
Performance Comparison Of A Roundabout Versus Two-Way Stop Controlled (Twsc) Intersections, Deogratias Eustace
Civil and Environmental Engineering and Engineering Mechanics Faculty Publications
The superior safety record of modern roundabouts is well known in Western Europe, Australia and in most British-influenced countries around the world. The experience from a single modern roundabout installed in the City of Manhattan, Kansas, some three years ago, also shares the same experience. A major study of the performance of Manhattan, Kansas, modern roundabout was conducted at Kansas State University (KSU) and was co-sponsored by Mac-Blackwell National Rural Transportation Study Center, Kansas State University, and the City of Manhattan. The study examined three intersections, one modern roundabout and two Two-Way Stop Controlled (TWSC) intersections with similar traffic conditions. …

Automatic generation of contours for graphical display and map plotting has been studied extensively since the early days of computing. The individual segments making up a contour line are often determined by subdividing the object of interest into small triangles and computing the contours assuming a linear variation on each triangle. However, efficient storage of contour data and the need to place labels (automatically) or to smooth the contours require that the contours be generated in continuous strings of segments. A simple approach to generate such strings is to sort the randomly generated contour segments. Since sorting can be time-consuming, …

In late June 1998, a major storm event occurred in the Adirondack Mountains in the vicinity of Keeseville, New York about 150 miles north of Albany. This storm resulted in unprecedented damage to the Canadian Pacific Railway (CPR) Canadian Mainline along the shores of Lake Champlain. The storm caused 14 major embankment failures and washouts, numerous minor failures, severe bridge foundation scour and a major mainline derailment.
Experimental And Theoretical Modeling Of Dynamically Loaded Surface Foundations On Granular Soils, Jeramy C. Ashlock
Experimental And Theoretical Modeling Of Dynamically Loaded Surface Foundations On Granular Soils, Jeramy C. Ashlock

The mechanical properties of a cohesionless granular medium are strongly dependent on the confining stress, which varies three-dimensionally under a surface foundation due to gravitational and surface loading effects. Success in predicting a foundation’s response to dynamic loading is therefore highly dependent on the appropriate choice of material properties for a given theoretical model. Presented in this thesis are critical results from an investigation of dynamically loaded square foundations on granular soil using a geotechnical centrifuge. From the results, it is shown that the characterization of the vertical mode of vibration of the square foundations via the homogeneous half-space theory …
