Download or read book Motorcoach Override of Elevated Exit Ramp Interstate 75 Atlanta Georgia March 2 2007 written by National Transportation Safety Board and published by Createspace Independent Publishing Platform. This book was released on 2008 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motorcoach then overrode the bridge rail, rotated clockwise, and fell 19 feet onto the southbound lanes of the interstate. The motorcoach came to rest on its left side (driver's side), perpendicular to the southbound lanes of Interstate 75. Two southbound passenger vehicles received minor damage from debris as the motorcoach fell onto Interstate 75; none of the passenger vehicle occupants were injured. Seven motorcoach occupants were killed: the driver, the driver's wife, and five passengers. Seven other passengers received serious injuries, and 21 passengers received minor injuries. Major safety issues identified in this accident include inadequate HOV traffic control devices, inadequate motor carrier driver oversight, lack of event data recorders on motorcoaches, and lack of motorcoach occupant protection.

Download or read book Jet Grouting written by Paolo Croce and published by CRC Press. This book was released on 2014-02-26 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike similar titles providing general information on ground improvement, Jet Grouting: Technology, Design and Control is entirely devoted to the role of jet grouting – its methods and equipment, as well as its applications. It discusses the possible effects of jet grouting on different soils and examines common drawbacks, failures and disadvantages, recent advances, critical reviews, and the range of applications, illustrated with relevant case studies. The book addresses several topics involving this popular worldwide practice including technology issues, the interpretation of the mechanisms taking place during the grouting, the quantitative prediction of their effects, the design of jet-grouted structures, and procedures for controlling jet grouting results. Discusses the design criteria for jet grouting projects and reviews existing design rules and codes of practice of different countries Provides practical methods for design calculations of the most important jet-grouted structures such as foundations, earth retaining walls, water cut-offs, bottom plugs, and provisional tunnel supports Includes the current standard control methods and most innovative techniques reported for the implementation of quality control and quality assurance procedures Jet Grouting: Technology, Design and Control analyzes the typical jet-grouted structures, such as foundations, earth retaining walls, water cut-offs, bottom plugs and tunnel supports, and serves as a practical manual for the correct use of jet grouting technology.

Download or read book Image Encryption written by Fathi E. Abd El-Samie and published by CRC Press. This book was released on 2013-12-14 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB® codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.

This book was released on 1998 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research study consisted of Phase II of the development and full-scale vehicle crash testing of a bullnose barrier concept for the treatment of median hazards. The bullnose guardrail consisted of a 12-gauge thrie beam rail supported by twenty-two wood posts, eleven posts on each side of the system. Horizontal slots were cut in the valleys of selected thrie beam sections to aid in vehicle capture as well as to reduce the buckling and bending capacities of the rail. Two full-scale crash tests were performed, both using a 2000-kg pickup truck. The first crash test, impacting at a speed of 100.2 km/h and an angle of 0 degrees, was unsuccessful following the rupture of the thrie beam and subsequent uncontrolled penetration of the vehicle behind the barrier. Computer simulation of the failed test was performed using LS-DYNA. Analysis of the simulation and full-scale test results led to the addition of two steel cables placed behind the top and middle humps of the thrie beam nose section to aid in truck containment without stiffening the barrier. Computer simulation of the modified design demonstrated successful containment of the pickup truck. The second test, impacting at a speed of 103.5 km/h and an angle of 0 degrees was determined to be successful according to the safety standards set forth by the Test Level 3 (TL-3) evaluation criteria described in the NCHRP Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features" (1993). The next phase of the bullnose barrier system design will be to complete the remaining crash tests needed for compliance with the NCHRP Report No. 350 safety standards for median barriers.

Download or read book Evaluation of the MGS Placed 6 In Behind a 6 in Tall AASHTO Type B Curb to MASH TL 3 written by Kellon Ronspies and published by . This book was released on 2020 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of curbs along roads is often required for certain functions such as drainage control, right-of-way reduction and sidewalk separation. However, curbs along roadways can adversely affect the interaction of errant vehicles with roadside barriers. Curbs placed near guardrail systems increase the propensity for vehicle override, vehicle underride, vehicle instability, and excessive rail loading during impact events. The Midwest Guardrail System (MGS) installed behind curbs was evaluated under National Cooperative Highway Research Program (NCHRP) Report 350 Test Level 3 (TL-3) criteria but has not been evaluated to American Association of State Highway Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) TL-3. Test nos. MGSC-7 and MGSC-8 were conducted on the MGS offset by 6 in. behind a 6-in. tall AASHTO Type B curb in accordance with MASH 2016 test designation nos. 3-10 and 3-11, respectively. During test no. MGSC-7, the 1100C vehicle impacted the system at 63.6 mph at an angle of 25.0 degrees and was successfully contained and redirected by the system. The system was rebuilt and tested again according to MASH test designation no. 3-11. In test MGSC-8, the 2270P vehicle impacted the system at 63.4 mph at an angle of 25.7 degrees and was successfully contained and redirected by the system. Upon the successful completion of the two full-scale crash tests, the MGS was deemed crashworthy to MASH 2016 TL-3 when placed within 6 in. behind a curb. Installation guidelines were presented to address implementation of the MGS with curb in various barrier configurations as well as in conjunction with a number of roadside features and special applications.
