Book Description
The Indiana Department of Transportation (INDOT) has installed guardrail systems on interstate highways and other highways in accordance with a variety of standards throughout the years. Traffic volume has increased and the posted speeds have been raised on most INDOT's interstate highways. Consequently, the characteristics of run-off-the-road (ROR) crashes may have changed. In the meantime, material prices have increased considerably and the guardrail maintenance and crash repair costs have increased accordingly. There is no doubt all these changes will not only greatly affect the ROR crash prediction, but also greatly affect the guardrail benefit/cost analysis. This study examined the current use of roadside guardrails on INDOT intestates, State highways, and US highways, roadways, including types and lengths of guardrails, types and numbers of guardrail end treatments, and field guardrail positions. Based on the records of total 4657 ROR crashes occurred in 2004 and 2006, this study investigated the characteristics of ROR crashes, such as frequencies and locations of ROR crashes, crash consequences (number of vehicles involved, injuries and fatalities), and the effects of main factors, in particular roadway geometrics, seasons and traffic volume, on the highways of different classes. Furthermore, this study investigated the features of vehicle-guardrail crashes, including impact positions and corresponding frequencies and consequences. ROR crash predictions were examined in all aspects in this study, including encroachment rates, crash probabilities, and severity probabilities. It was found that the encroachment rates obtained by this study are less than those in the AASHTO Roadside Design Guide. This study evaluated the issues associated with the guardrail crash repair costs, such as parts costs, labor costs, and equipment costs.

Book Description
Maintenance, Safety, Risk, Management and Life-Cycle Performance of Bridges contains lectures and papers presented at the Ninth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2018), held in Melbourne, Australia, 9-13 July 2018. This volume consists of a book of extended abstracts and a USB card containing the full papers of 393 contributions presented at IABMAS 2018, including the T.Y. Lin Lecture, 10 Keynote Lectures, and 382 technical papers from 40 countries. The contributions presented at IABMAS 2018 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of bridge maintenance, safety, risk, management and life-cycle performance. Major topics include: new design methods, bridge codes, heavy vehicle and load models, bridge management systems, prediction of future traffic models, service life prediction, residual service life, sustainability and life-cycle assessments, maintenance strategies, bridge diagnostics, health monitoring, non-destructive testing, field testing, safety and serviceability, assessment and evaluation, damage identification, deterioration modelling, repair and retrofitting strategies, bridge reliability, fatigue and corrosion, extreme loads, advanced experimental simulations, and advanced computer simulations, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of more rational decision-making on bridge maintenance, safety, risk, management and life-cycle performance of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers and engineers from all areas of bridge engineering.

Book Description
The technological revolution linked to high speed rail (HSR) has been accompanied by myths and claims about its contribution to society and the economy. Although HSR is unquestionably a technological advance that has become a symbol of modernity, this review and analysis of the international experiences shows that the conditions necessary to have a positive impact, economically, socially and environmentally, are enormously restrictive. The Economics and Politics of High Speed Rail: Lessons from Experiences Abroad, by Daniel Albalate and Germà Bel, introduces the main questions policy makers and scholars should examine when considering and studying HSR implementation, with particular emphasis on the US’s recent interest in this technology and possible application in California. Albalate and Bel then review the experiences of the most significant implementations of HSR around the globe. This in-depth international perspective includes chapters on the pioneers of HSR (Japan and France), the European followers (Germany, Spain and Italy), as well as Asian experiences in China, Taiwan, and Korea. Albalate and Bel’s study provides a clear distinction between the myths and realities associated with this transportation innovation. Among the most relevant findings, this study highlights how HSR projects that do not satisfy highly restrictive conditions—on mobility patterns, measured costs, and economically rational designs—that make it desirable have been the source of huge financial debacles and the economic failure of HSR in most cases, which result in unfortunate consequences for taxpayers. The Economics and Politics of High Speed Rail is a rigorous investigation of the economic and political challenges and ramifications of implementing new public transportation technology.

Book Description
This roadside safety design package has been developed to satisfy a need for training in this area. It is hoped that all persons involved in the design, construction, operation, and maintenance of highways will become familiar with the concepts contained in the program. The concepts and practices discussed come from those contained in the AASHTO publication, "Highway Design and Operational Practices Related to Highway Safety". They are discussed in considerable depth in this program and should provide a good working knowledge of roadside safety design. Much of the program is oriented around freeways; however, the principles apply equally toward the lower order highway.
