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.

Urbanization is a global phenomenon that hugely constrains existing transportation infrastructure in cities. Urban transportation (UT) challenges are more significant in developing countries with rapid development as the land occupation is dense.Limited urban space and infrastructure fail to meet the increasing traffic demands and to provide reasonable service quality. Therefore betterment of UT systems is more required than ever. Infrastructural development and transportation operations are mainly directed at citizen welfare and it requires huge capital investments. States initiate urban development by inviting private participation so that operational and commercial risks are minimized and quality of execution is better. Several aspects in planning and management of global UT projects are common. But the approach and solutions are typically developed for a local context and relevance. Specific UT challenges are land use planning, socioeconomic distribution, project designing, implementation, financial analysis and governmental policies. A comprehensive background of UT systems, challenges involved and various approaches adopted by different countries are presented along with five real-life Asian cases. The book is aimed as a one-point reference on modern day developments on urban transportation for a readership of consultants, practitioners, developers, policy makers, and academicians

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.
