Download or read book Transportation Librarian's Toolkit written by Maggie Sacco and published by . This book was released on 2007 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Transportation Librarian's Toolkit is a product of the Transportation Library Connectivity pooled fund study, TPF- 5(105), a collaborative, grass-roots effort by transportation libraries to enhance information accessibility and professional expertise to serve the transportation community. At the time of publication study members included state DOT libraries in Washington, Oregon, Montana, Kansas, Minnesota, Ohio, Pennsylvania, Tennessee and Louisiana; and the University Transportation Center at the University of Wisconsin-Madison. In addition to the Toolkit, the study has also published an Interim Report of the formation, major activities and accomplishments of the study from its launch in October 2004 through its third annual meeting in September 2007. The Technical Advisory Committee members of the pooled fund study were instrumental in creating this toolkit, which is a product of the collective work of the study. The purposes of this toolkit are to ease the learning curve of those new to librarianship and/or transportation; to pull together the collective wisdom of pooled fund members on topics that the pooled fund has addressed through its work of connecting and networking transportation libraries; to serve as a living document, updated frequently in print and online; to capture some of the institutional memory that is leaving the DOTs as waves of retirements loom; and to give transportation librarians of varying experience levels and work situations some tools to inspire, enhance and streamline librarians' work as well as library operations to make the transportation library an indispensable resource within the parent organization.

This book was released on 2013-06-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research project, "Dynamic Bridge Substructure Evaluation and Monitoring," was sponsored by the Federal Highway Administration (FHWA) under contract number DTFH61-96- C-00030. The research was funded to investigate the possibility that by measuring and modeling the dynamic response characteristics of a bridge substructure, one could determine the condition and safety of the substructure and identify its foundation type (shallow or deep). Determination of bridge foundation conditions with this approach may be applied to quantify losses in foundation stiffness caused by earthquake, scour, and impact events. Identification of bridge foundation type may be employed to estimate bridge stability and vulnerability under dead and live load ratings, particularly for unknown bridge foundations. Chapter 2 introduces the research project scope and presents the results of a literature review of related topics. Chapter 3 describes the bridges in Texas that were selected for modal vibration tests during the research.

Book Synopsis Practice of Rumble Strips and Rumble Stripes by : Omar Smadi
Download or read book Practice of Rumble Strips and Rumble Stripes written by Omar Smadi and published by . This book was released on 2016 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis documents current practices used by states installing rumble strips and explores variations in practice in terms of design, criteria, and locations for installation, maintenance, perceived benefits, communication of benefits, and important issues. Information was acquired through a literature review, survey on current practice, and case examples. The survey also included questions specific to the state of practice for rumble stripes, which is the term used when the pavement marking lines are painted on the rumble strip in an effort to increase visibility during inclement weather conditions. The findings indicate that two-thirds of the state agencies rely on traditional methods to address the noise issue: skipping rumbles in residential areas, adjusting their depth, or not installing rumbles at all. The overwhelming majority of responding states, 83%, have developed policies or guidance to modify their rumble design practices to be sensitive to cyclists. Fewer than half the respondents have developed policies/guidance to address pavement deterioration; several agencies indicated that pavement condition is a factor on whether to install a rumble or not. The survey also showed that very few state DOTs have created public campaigns to explain that the use of rumbles improves safety so that complaints regarding noise, bicycle issues, and other are minimized.

Download or read book Low-cost Treatments for Horizontal Curve Safety written by and published by . This book was released on 2006 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 25 percent of fatal crashes occur at or near a horizontal curve. Hence, addressing the safety problem at horizontal curves is one of the 22 emphasis areas of the Strategic Highway Safety Plan prepared by AASHTO. Also, crashes at horizontal curves are a big component of the road departure crash problem, which is one of FHWA's three focus areas. This publication was prepared to provide practical information on low-cost treatments that can be applied at horizontal curves to address identified or potential safety problems. The publication concisely describes the treatment; shows examples; suggests when the treatment might be applicable; provides design features; and where available, provides information on the potential safety effectiveness and costs. The treatments include: Basic traffic signs and markings found in the MUTCD; Enhanced traffic control devices; Additional traffic control devices not found in the MUTCD; Rumble strips; Minor roadway improvements; Innovative and experimental treatments. The publication concludes with a description of maintenance activities that should be conducted to keep the treatments effective.
