Book Synopsis Transportation Librarian's Toolkit by : Maggie Sacco
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 2016-04-07 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB Special Report 320: Interregional Travel: A New Perspective for Policy Making examines the demand for and supply of interregional transportation in the United States. Major additions to transportation infrastructure, including high-speed rail, are being considered for some of the country’s most heavily traveled 100- to 500-mile corridors. The availability and use of the automobile, airplane, and train for interregional travel are reviewed along with the rejuvenated intercity bus. U.S. interregional corridors and transportation options are contrasted with those in Japan and Europe, where substantial investments have been made in passenger rail. Public investments in new, long-lived transportation infrastructure can be risky because of uncertainty about future demand and the development of new technologies and competing transportation services. Decisionmakers in interregional corridors face the added challenge of having to coordinate investments across multiple jurisdictions. The report recommends actions to reduce this uncertainty and create stronger institutional means for developing the country’s interregional corridors. TR News 303 features an article on Interregional Travel: A New Perspective for Policy Making. A video about the research is now available: At the 2016 TRB Annual Meeting, January 10-14, 2016, a session entitled Interregional Travel: Policymaking from a New Perspective was webcast live. These videos provide an overview of various components of the project.

Book Synopsis The End of Automobile Dependence by : Peter Newman
Download or read book The End of Automobile Dependence written by Peter Newman and published by Island Press. This book was released on 2015-08-11 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities will continue to accommodate the automobile, but when cities are built around them, the quality of human and natural life declines. Current trends show great promise for future urban mobility systems that enable freedom and connection, but not dependence. We are experiencing the phenomenon of peak car use in many global cities at the same time that urban rail is thriving, central cities are revitalizing, and suburban sprawl is reversing. Walking and cycling are growing in many cities, along with ubiquitous bike sharing schemes, which have contributed to new investment and vitality in central cities including Melbourne, Seattle, Chicago, and New York. We are thus in a new era that has come much faster than global transportation experts Peter Newman and Jeffrey Kenworthy had predicted: the end of automobile dependence. In The End of Automobile Dependence, Newman and Kenworthy look at how we can accelerate a planning approach to designing urban environments that can function reliably and conveniently on alternative modes, with a refined and more civilized automobile playing a very much reduced and manageable role in urban transportation. The authors examine the rise and fall of automobile dependence using updated data on 44 global cities to better understand how to facilitate and guide cities to the most productive and sustainable outcomes. This is the final volume in a trilogy by Newman and Kenworthy on automobile dependence (Cities and Automobile Dependence in 1989 and Sustainability and Cities: Overcoming Automobile Dependence in 1999). Like all good trilogies this one shows the rise of an empire, in this case that of the automobile, the peak of its power, and the decline of that empire.

Book Synopsis Evaluation of Bridge Approach Rails by : Roger P. Bligh
Download or read book Evaluation of Bridge Approach Rails written by Roger P. Bligh and published by . This book was released on 1992 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent study on the performance of guardrail-to-bridge rail transitions revealed that many widely used designs do not meet current safety standards. As a result, the Federal Highway Administration (FHWA) requested that the Arizona Department of Transportation verify the safety performance of its standard transition designs. Three transition designs currently being used by ADOT were evaluated through a combined program of computer simulation and full-scale crash testing. The standard ADOT wood post transition, incorporating a channel rubrail and two different sizes of timber posts at a reduced post spacing near the bridge rail end, was found to be in compliance with National Cooperative Highway Research Program (NCHRP) Report 230 performance criteria. The standard ADOT steel post transition with channel rubrail was also found to be in compliance with NCHRP Report 230 requirements when impacted near the end of the bridge rail. However, the upstream end of the steel post transition required modification to eliminate deficiencies identified during testing. The modified design, which terminated the channel rubrail behind a W6x9 guardrail post, was successfully crash tested.

Book Synopsis Vehicular Crash Tests of the California ST-20 Bridge Rail by : John Russell Jewell
Download or read book Vehicular Crash Tests of the California ST-20 Bridge Rail written by John Russell Jewell and published by . This book was released on 2004 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the course of this project a see-through steel bridge rail (Type California ST-20) was developed and tested. The ST-20, as tested, is at the limits of meeting the NCHRP Report 3501 TL-4 test matrix. The bridge rail also met the requirements established in the AASHTO Bridge Design Specifications for use as a bicycle rail and is considered an aesthetically pleasing see-through bridge rail. The barrier, as tested, uses steel posts at 3-m spacing to support four boxbeam rails and one additional handrail to meet the height requirements for bicycles. Because the ST-20 is based on a TL-4 bridge rail from Wyoming DOT3,4, only Test 4-11 (NCHRP Report 350) was considered necessary.
Book Synopsis Design and Evaluation of the TL-4 Minnesota Combination Traffic/bicycle Bridge Rail by : Karla A. Polivka
Download or read book Design and Evaluation of the TL-4 Minnesota Combination Traffic/bicycle Bridge Rail written by Karla A. Polivka and published by . This book was released on 1998 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combination traffic and bicycle bridge rail was developed and crash tested. The combination bridge rail was constructed with a standard New Jersey safety shaped barrier and special steel panels formed from tubular steel posts and rails, and square vertical spindle bars. Two cables were installed inside the tubular rails to prevent detachment of large pieces of debris from causing hazardous conditions for vehicles and pedestrians below. Although the crash tested bridge rail was constructed using the New Jersey safety shape, it is believed that this combination traffic/bicycle bridge rail could be easily adapted to other safety shape barriers or rectangular parapets with no need for further crash testing. Due to the modular nature of the steel panel sections, the combination traffic/bicycle bridge rail can be repaired very easily following a vehicular impact. Two full-scale vehicle crash tests were performed on Minnesota's combination traffic/bicycle bridge railing. The tests were conducted and reported in accordance with the requirements specified in NCHRP Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features" (1993). The safety performance of the combination traffic/bicycle bridge rail was determined to be acceptable according to Test Level 4 of the NCHRP Report No. 350 criteria
