Download or read book MASH TL-4 Evauation of the TxDOT Type C2P Bridge Rail written by William F. Williams (Transportation engineer) and published by . This book was released on 2017 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to evaluate the impact performance of the Texas Department of Transportation (TxDOT) Type C2P Bridge Rail according to the safety-performance evaluation guidelines included in the American Association of State Highway and Transportation Officials Manual for Assessing Safety Hardware (MASH) for Test Level Four (TL-4). This report describes the TxDOT Type C2P Bridge Rail , documents the impact performance of the bridge rail system according to MASH TL-4 evaluation criteria for longitudinal barriers, and presents recommendations regarding implementation. MASH Tests 4-10 and 4-11 evaluate a barrier's ability to successfully contain and redirect passenger vehicles and evaluate occupant risk. MASH Test 4-12 evaluates the structural adequacy of the bridge rail. All three tests were performed on the TxDOT Type C2P Bridge Rail. For Test 4-12, the post welds were not properly fabricated according to the project design drawings. As a result, some post welds in the immediate impact area did rupture from the MASH Test 4-12 truck impact. These ruptured post welds did aggravate the stability of the single unit truck during the test. For subsequent tests, the posts were welded correctly as per the project drawings. The bridge rail posts, with the correct post welds, should only improve the performance of the single unit truck. The TxDOT Type C2P Bridge Rail performed acceptably for MASH TL-4.

Book Synopsis TL-4 Crash Testing of the F411 Bridge Rail by : Dean C. Alberson
Download or read book TL-4 Crash Testing of the F411 Bridge Rail written by Dean C. Alberson and published by . This book was released on 2004 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Texas Department of Transportation (TXDOT) and Florida Department of Transportation (FDOT) frequently receive requests to provide aesthetically pleasing traffic rails for use on select bridges and roadways. TxDOT, in response to providing context sensitive design alternatives, initiated a project to develop additional aesthetically pleasing rail alternatives. Under a previous TxDOT project, the F411 bridge rail was constructed and crash tested to Test Level 3 (TL-3). The TL-3 test is a 4405-lb (2000 kg) pickup impacting the railing at 25 degrees and 62.2 mi/h (100 krn/h). This test requires both containment and stability, and non-overturning. Since some breakage of the parapet is possible, potential for vehicle snagging is likely. Vehicle snagging can contribute to vehicle instabilities in the redirection sequence and potential rollover. The TxDOT F411 bridge rail contained and redirected the vehicle, which remained upright during and after the collision period. The bridge rail met the required specifications for NCHRP Report 350 test 3-11. The objective of this research is the full-scale crash test and evaluation of the F411 to Test Level 4 (TL-4). The most direct approach for accomplishing the objectives of this task is to perform a full-scale TL-4 crash test of this railing design. The TL-4 vehicle is a single-unit box-van truck impacting the railing at 15 degrees and 49.7 mi/h (80 krn/h). While containment is required, overturning of the vehicle 90 degrees is an acceptable test outcome. The TxDOT F411 bridge rail performed acceptably for NCHRP Report 350 test 4-12. Based on the performance of the F411 bridge rail in the full-scale crash test to TL-4 test conditions, the F411 may be used where containment of 18,000 lb single-unit trucks is desired.

Book Synopsis MASH TL-3 Evaluation of 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition by : William F. Williams (Transportation engineer)
Download or read book MASH TL-3 Evaluation of 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition written by William F. Williams (Transportation engineer) and published by . This book was released on 2020 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the tests reported herein was to assess the performance of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition according to the safety-performance evaluation guidelines included in AASHTO MASH. The crash tests were performed in accordance with MASH TL-3, which involves two full-scale crash tests (MASH Tests 3-20 and 3-21). However, MASH states that when there are transitions between two barrier types with different stiffness, one from a more flexible barrier and the other to a more rigid barrier, a full-scale crash test is recommended for both types. Therefore, MASH Test 3-21 was performed at the transition from the thrie beam rail to bridge rail, and at the transition from the W-beam rail to thrie beam rail. This report provides details of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition, detailed documentation of the crash tests and results, and an assessment of the performance of the 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition for MASH TL-3 transition evaluation criteria. The 2019 MASH 2-Tube Bridge Rail Thrie Beam Transition performed acceptably for MASH TL-3 transitions.

Book Synopsis MASH Test 3-21 on TL-3 Thrie Beam Transition Without Curb by : Dusty R. Arrington
Download or read book MASH Test 3-21 on TL-3 Thrie Beam Transition Without Curb written by Dusty R. Arrington and published by . This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project evaluated the impact performance of a modified Texas Department of Transportation (TxDOT) thrie beam transition to rigid concrete barrier without a curb element below the transition rail. In a previous test described in TxDOT Research Report 0-4564, a thrie beam transition without curb failed to meet National Cooperative Highway Research Program (NCHRP) Report 350 performance criteria. However, it could not be discerned whether the vehicle instability observed in that test was attributable to the missing curb or the rotation of the thrie beam transition rail into the sloped face of the concrete safety shape rail at the bridge end connection point.

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.

Book Synopsis Enhancing the Resilience of the Nation's Electricity System by : National Academies of Sciences, Engineering, and Medicine
Download or read book Enhancing the Resilience of the Nation's Electricity System written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-10-25 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
