This book was released on 2020 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combination bridge rail was designed and crash tested for Iowa Department of Transportation (Iowa DOT) for use alongside a pedestrian/bicycle bridge pathway that would satisfy Manual for Assessing Safety Hardware (MASH) 2016 Test Level 2 (TL-2) criteria. Currently, Iowa DOT employs a combination bridge rail that utilizes a concrete parapet that had previously been successfully evaluated according to National Cooperative Highway Research Program (NCHRP) Report No. 350 TL-4 criteria. While the parapet had been successfully evaluated, the combination bridge rail system as a whole had not been evaluated to any crash test standards. Thus, Iowa DOT desired that researchers at Midwest Roadside Safety Facility (MwRSF) test the new combination bridge separation barrier to current MASH 2016 TL-2 standards to use in place of their current, untested system. The new combination bridge rail system consisted of a pedestrian/bicycle railing mounted atop a vertical concrete parapet. The pedestrian/bicycle railing featured spliced longitudinal rails welded atop structural steel tube posts with welded steel base plates for attachment atop the parapet. In full-scale crash test no. IBBR-1, the 2270P vehicle was successfully redirected, resulting in minimal damage to the rail from plastic deformation and minimal damage to the parapet. This combination bridge rail design minimized the concrete parapet height that could be used in order to safely redirect the impacting vehicle, thus providing many advantages such as reduced dead weight on bridges, decreased construction costs, and improved sight lines.

Book excerpt: Iowa Department of Transportation (Iowa DOT) typically builds separation barriers between vehicle and pedestrian/bicycle facilities when sidewalks or trails are present on vehicular bridges. Currently, Iowa DOT employs a combination bridge rail that utilizes a concrete parapet that had previously been successfully evaluated to National Cooperative Highway Research Program (NCHRP) Report No. 350 Test Level 4 (TL-4) criteria for these situations. While the parapet had been successfully evaluated, the combination bridge rail system as a whole had not been evaluated to any crash test standards. Iowa DOT desired that researchers at Midwest Roadside Safety Facility (MwRSF) design and test a combination bridge separation barrier to current Manual for Assessing Safety Hardware, Second Edition (MASH 2016) TL-2 standards to use in place of their current, untested system. During this effort, previous combination rails, low-height vertical parapets, and zone of intrusion (ZOI) studies were reviewed to provide guidance on system design. A simulation effort was also performed to aid in height selection of the parapet, as well as placement of the attached bicycle rail to reduce the amount of negative vehicle-to-rail interaction with the system. Using the gathered data, a full system design was produced. It was then recommended that the proposed system be evaluated to MASH 2016 test designation no. 2-11 in order to assess the system's performance during a vehicle impact scenario.

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

This book was released on 2016-08-01 with total page 1204 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-disciplinary approach to transportation planning fundamentals The Transportation Planning Handbook is a comprehensive, practice-oriented reference that presents the fundamental concepts of transportation planning alongside proven techniques. This new fourth edition is more strongly focused on serving the needs of all users, the role of safety in the planning process, and transportation planning in the context of societal concerns, including the development of more sustainable transportation solutions. The content structure has been redesigned with a new format that promotes a more functionally driven multimodal approach to planning, design, and implementation, including guidance toward the latest tools and technology. The material has been updated to reflect the latest changes to major transportation resources such as the HCM, MUTCD, HSM, and more, including the most current ADA accessibility regulations. Transportation planning has historically followed the rational planning model of defining objectives, identifying problems, generating and evaluating alternatives, and developing plans. Planners are increasingly expected to adopt a more multi-disciplinary approach, especially in light of the rising importance of sustainability and environmental concerns. This book presents the fundamentals of transportation planning in a multidisciplinary context, giving readers a practical reference for day-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning software packages Get up to date on the latest standards, recommendations, and codes Developed by The Institute of Transportation Engineers, this book is the culmination of over seventy years of transportation planning solutions, fully updated to reflect the needs of a changing society. For a comprehensive guide with practical answers, The Transportation Planning Handbook is an essential reference.

Book excerpt: The purpose of this document is to identify and provide design guidelines for bridge scour and stream instability countermeasures that have been implemented by various State departments of transportation (DOTs) in the United States. Countermeasure experience, selection, and design guidance are consolidated from other FHWA publications in this document to support a comprehensive analysis of scour and stream instability problems and provide a range of solutions to those problems. The results of recently completed National Cooperative Highway Research Program (NCHRP) projects are incorporated in the design guidance, including: countermeasures to protect bridge piers and abutments from scour; riprap design criteria, specifications, and quality control, and environmentally sensitive channel and bank protection measures. Selected innovative countermeasure concepts and guidance derived from practice outside the United States are introduced. In addition, guidance for the preparation of Plans of Action ...
