To reveal the internal relationship between short-and long-term changes in the number of traffic accidents, traffic safety education expenditures, related technology expenditures, passenger turnover, and the number of private vehicles for a period from 1990 to 2018, a vector autoregressive model (VAR) was elaborated based on the respective time-series data. After the augmented Dicky-Fuller and Johansen cointegration tests, a vector error correction model (VECM) was also adopted to analyze their impulse responses and variances. This study can help optimize the road traffic management strategy to reduce the number of traffic accidents and develop a safer and more efficient transportation system. The results show that: 1) In the long run, the increase in passenger turnover is the internal cause of the increase in traffic accidents; 2) In the short-term scale, the education and R & D technology expenditures have a negative impact on the occurrence of traffic accidents.

This synthesis will be of interest to transportation planners, environmental analysts, and government officials at the federal, state, regional, and local levels. It describes the state of the practice with respect to the procedures and methodologies used by planning agencies at all levels to plan and evaluate alternative multimodal passenger transportation and to integrate these plans with related land use and environmental issues. This report of the Transportation Research Board describes the federal studies and guidelines that are available and presents the findings of an extensive survey of state, regional, and local agencies to identify the evaluation methods that are being used in the practice. Selected case studies for five types of modal evaluation are presented: intercity corridor, regional study, regional screening, urban corridor, and regional programming.

Each track consisted of a plenary session followed by three concurrent breakout sessions. These proceedings follow the conference format, with the plenary sessions and the breakout sessions for each of the five tracks presented in chronological order. The breakout sessions and the closing session gave participants the opportunity to provide ideas and suggestions on further research, technology transfer, and training. Research topics identified for potential consideration are listed in the section on concluding remarks. The conference also featured an interactive poster session. Summaries provided by the poster authors are presented in Appendix A. The conference attracted 130 participants from Canada, Germany, Japan, the Netherlands, South Africa, and the United States, and featured transportation specialists who offered real-world expertise on the application of performance metrics and case studies.

In recent years, the application of intelligent transportation systems (ITS) has steadily expanded, and has become a hot spot of common interest to universities, scientific research institutes, enterprises and institutions in the transportation field. ITS is the product of the deep integration of modern high-tech in the transportation industry, and its development has accompanied that of modern high-tech. ITS is now also becoming part of the Internet of Things (IoT), and is expected to contribute significantly to making our cities smarter and connecting with other infrastructure. Although there are many monographs and textbooks on intelligent transportation, with the advancement of technology and changes in demand, the key technologies of ITS are also rapidly changing. This book chiefly focuses on the main technologies of ITS, examining them from four perspectives: “sense” (perception and management of traffic information, chapters 2 & 3), “transmission” (interaction of traffic information, chapter 4), “prediction” (prediction of traffic states, chapter 6) and “application” (intelligent transportation applications, chapters 6 through 10). Given its scope, the book can be used as a textbook for undergraduates or graduates, as well as a reference book for research institutes and enterprises. This book emphasizes the use of basis traffic engineering principles and state-of-art methodologies to develop functional designs. It largely reflects the authors’ own experience in adapting these methodologies to ITS design. For example, the book addresses various forms of data collection, models used to predict and evaluate traffic states, comprehensive description in connected vehicles, applications for users and traffic managers, etc. The knowledge gained here will allow designers to estimate the performance differences among alternatives and gauge their potential benefits for functional design purposes. To gain the most from the book, readers should be somewhat familiar with the field of traffic engineering and interested in ITS.

"This report provides a comprehensive analytical framework and related tools that private-sector freight transportation modes and public-sector transportation interests can use to estimate private and public benefits to evaluate potential freight infrastructure investments. Using interviews with transportation planners and an extensive review of prior research and a review of current methods used to assess freight benefits or prioritize improvement projects, the research developed a freight evaluation framework with three main functions: (1) to enhance public planning and decision-making processes regarding freight; (2) to supplement benefit/cost assessment with distributional impact measures; and (3) to advance public-private cooperation. The framework is capable of handling projects that span all of the different modes and able to assess benefits from a variety of project types, including those that improve freight operations, as well as generate more capacity through infrastructure expansion. The research, by developing a practical set of formats for information collection, will support public-private agency discussions by helping all parties understand the wide range of perspectives and interests in potential freight investments."--Pub. desc.

The book consists of papers on selected topics of dependability analysis in computer systems and networks which were discussed during the 17th DepCoS-RELCOMEX conference held in Wrocław, Poland, from June 27th to July 1st, 2022. Their collection will be an interesting source material for scientists, researchers, practitioners and students who are dealing with design, analysis and engineering of computer systems and networks and must ensure their dependable operation. Being probably the most complex technical systems ever engineered by man (and also, the most dynamically evolving ones), organization of contemporary computer systems and networks cannot be interpreted only as a structure built on the base of unreliable technical resources. Their evaluation must take into account a unique blend of interacting people, networks (together with mobile properties, cloud organization, Internet of Everything, etc.) and a large number of users dispersed geographically and constantly producing an unconceivable number of applications. Research methods being continuously developed for dependability analyses apply newest results of artificial and computational intelligence. Selection of papers in this book illustrates broad range of topics, often multi-disciplinary, which is considered in present-day dependability explorations; it also reveals an increasing role of the latest methods based on machine/deep learning and neural networks in these studies.
