Available in PDF, EPUB and Kindle. Book excerpt: This research study consisted of the development and testing of a short-radius guardrail system for protection of hazards near intersecting roadways and capable of meeting the Test Level 3 (TL-3) impact conditions of the NCHRP Report No. 350 criteria. A short-radius system was designed and consisted of a curved and slotted thrie beam nose section with two adjacent slotted thrie beam sections supported by breakaway posts. One side of the system was attached to a TL-3 steel post transition while the other was attached to a TL-2 end terminal. A series of four full-scale crash tests were conducted on the short-radius guardrail system.

Book Synopsis Phase II Development of a Bullnose Guardrail System for Median Applications by : Bob W. Bielenberg
Download or read book Phase II Development of a Bullnose Guardrail System for Median Applications written by Bob W. Bielenberg and published by . 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 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 2016-01-26 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.
Book Synopsis A Guide for Achieving Flexibility in Highway Design by :
Download or read book A Guide for Achieving Flexibility in Highway Design written by and published by AASHTO. This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

Book Synopsis Guardrail Performance and Design by : Jarvis Dale Michie
Download or read book Guardrail Performance and Design written by Jarvis Dale Michie and published by . This book was released on 1971 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barrier installations are warranted (or justified) only at highway locations where the consequence of an errant vehicle leaving the roadway is judged to be more hazardous than the impact with the barrier installation. A six degree-of-freedom mathematical model was found to be useful in describing dynamic behavior of a vehicle during impact. Predictions of vehicle and barrier behavior correlated with results obtained from full-scale crash tests. Crash conditions simulated with a computer were used to identify and evaluate vehicle static and dynamic as well as barrier parameters. Vehicle weight, yaw mass moment of inertia, and deformation constant were found to be significant.
