This publication contains criteria, test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations, as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). It also supplements national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS.

The Manual of Tests and Criteria contains criteria, test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations, as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). As a consequence, it supplements also national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS. At its ninth session (7 December 2018), the Committee adopted a set of amendments to the sixth revised edition of the Manual as amended by Amendment 1. This seventh revised edition takes account of these amendments. In addition, noting that the work to facilitate the use of the Manual in the context of the GHS had been completed, the Committee considered that the reference to the “Recommendations on the Transport of Dangerous Goods” in the title of the Manual was no longer appropriate, and decided that from now on, the Manual should be entitled “Manual of Tests and Criteria"".

For thousands of years, the underground has provided humans refuge, useful resources, physical support for surface structures, and a place for spiritual or artistic expression. More recently, many urban services have been placed underground. Over this time, humans have rarely considered how underground space can contribute to or be engineered to maximize its contribution to the sustainability of society. As human activities begin to change the planet and population struggle to maintain satisfactory standards of living, placing new infrastructure and related facilities underground may be the most successful way to encourage or support the redirection of urban development into sustainable patterns. Well maintained, resilient, and adequately performing underground infrastructure, therefore, becomes an essential part of sustainability, but much remains to be learned about improving the sustainability of underground infrastructure itself. At the request of the National Science Foundation (NSF), the National Research Council (NRC) conducted a study to consider sustainable underground development in the urban environment, to identify research needed to maximize opportunities for using underground space, and to enhance understanding among the public and technical communities of the role of underground engineering in urban sustainability. Underground Engineering for Sustainable Urban Development explains the findings of researchers and practitioners with expertise in geotechnical engineering, underground design and construction, trenchless technologies, risk assessment, visualization techniques for geotechnical applications, sustainable infrastructure development, life cycle assessment, infrastructure policy and planning, and fire prevention, safety and ventilation in the underground. This report is intended to inform a future research track and will be of interest to a broad audience including those in the private and public sectors engaged in urban and facility planning and design, underground construction, and safety and security.

Long-term economic growth and increasing vehicle congestion is creating a greater demand for efficient and safe transportation. The high cost of maintaining and fixing pre-existing infrastructure is leading the industry to realize that sustainable long-term transportation planning is needed to keep pace with the growing economy. Building a Sustainable Transportation Infrastructure for Long-Term Economic Growth examines contemporary transportation issues through the lens of various modes of transportation while also focusing on the importance of sustainability, urban planning, and funding. The book covers the topics of sustainability and climate change, public management and planning, financing of transportation infrastructure, and revenue and spending issues facing modern transportation infrastructure. It is ideally designed for engineers, planners, government officials, transportation specialists, legislators, researchers, academicians, students, and industry professionals seeking current research on sustainable transport systems.

This book analyzes Liberia's transport connectivity and identifies existing bottlenecks and possible growth potentials, using spatial techniques and data, including the first-ever georeferenced detailed road network data in Liberia.

This book is about the design of vehicles with wheels that are powered by human muscles alone. These can provide affordable, sustainable, and healthy transportation to people around the globe. The term Human-Powered Vehicle, or HPV, is sometimes used to denote a sub-class of vehicles including only high-performance bicycles or tricycles equipped with aerodynamic fairings. More generally, the term refers to any semi-recumbent bicycle. But the term should properly refer to any means of carriage, conveyance, or transport that is powered solely by human muscles. This book is limited to design of human-powered vehicles for land use. There are many reasons why the design and use of such vehicles is beneficial. In developed countries, using an HPV in lieu of an automobile (or in lieu of a second automobile for a family) can save $5,000 to $10,000 each year, while improving health and reducing emissions of greenhouse gases and pollutants. Greenhouse gas emission will be reduced by more than 4,000 kg per year due to the corresponding reduction in energy consumption of more than 17,000 kWh. In addition, infrastructure for cycling is far less costly than highways designed for automotive traffic. Human-powered vehicles were originally designed for transportation, and that is still their most important use. HPVs today provide clean, quiet, and efficient transportation. Perhaps the most compelling reason to use HPVs is sustainability: the environmental footprint of HPVs is typically much, much smaller than that of other modes of transportation. Despite these commonalities, HPVs are used by a variety of different people for a wide range of diverse reasons, including recreation, competition, cost, health, transportation, and concern for the environment. The contents include manufacturing processes and materials, performance modeling, handling, drivetrains, structures, components, human performance, and design strategies.

In "Forensic Media," Greg Siegel considers how photographic, electronic, and digital media have been used to record and reconstruct accidents, particularly high-speed crashes and catastrophes. Focusing in turn on the birth of the field of forensic engineering, Charles Babbage's invention of a "self-registering apparatus" for railroad trains, flight-data and cockpit voice recorders ("black boxes"), the science of automobile crash-testing, and various accident-reconstruction techniques and technologies, Siegel shows how "forensic media" work to transmute disruptive chance occurrences into reassuring narratives of causal succession. Through historical and philosophical analyses, he demonstrates that forensic media are as much technologies of cultural imagination as they are instruments of scientific inscription, as imbued with ideological fantasies as they are compelled by institutional rationales. By rethinking the historical links and cultural relays between accidents and forensics, Siegel sheds new light on the corresponding connections between media, technology, and modernity.

A small federal agency, NMB facilitates labour relations in two key transportation sectors -- railroads and airlines -- through mediation and arbitration of labour disputes and overseeing union elections. Established under the Railway Labor Act, NMB's primary responsibility is to prevent work stoppages in these critical industries. This book discusses the national mediation board's strengthening plan and control to better facilitate rail and air labour relations.
