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. …

Techniques For Improving Energy Efficiency At Water Supply Pumping Stations, Lindell Ormsbee, Thomas M. Walski, Donald V. Chase, Wayne W. Sharp

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This report describes the application of methods presented in Engineer Technical Letter (ETL) "Energy Efficiency at Water Supply Pumping Stations'' to the Washington, DC, and vicinity water system.

Both the ETL and this report were prepared under the Water System Operation, Maintenance and Rehabilitation Work Unit (CWIS 31794) of the Water Supply and Conservation Research Program. The technical monitors for this program in the Office, Chief of Engineers, were Mr. James Ballif (DAEN-ECE-B) and Mr. Robert Daniel (DAEN-CWP-D). The work was conducted at the US Army Engineer (USAE) Waterways Experiment Station (WES), Vicksburg, Miss., and the University of Kentucky (UK) …

Technical Report El-88-18: Reliability Of The Federally Owned Water Main System, Donald V. Chase, Lindell Ormsbee, Thomas M. Walski

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

The reliability of the Federally Owned Water Main (FOWM) system was examined, and recommendations to improve system reliability are made. The existing FOWM system is very dependent upon three different pipe links.

The first and most important link is the Francis Scott Key Bridge river crossing. This link carries the entire FOWM supply, and if taken out of service, an alternate means of supply must be used. At present, the only alternate source of supply is through interconnections with the adjacent Arlington County, Virginia, system.

The second vital link is the 30-in. steel main which extends from the Key Bridge …
