Book Description
This book addresses the reader interested in vehicular traffic phenomena, who have not learned about them before. It presents traffic phenomena like traffic breakdown and the emergence of moving traffic jams by showcasing empirical traffic data measured in real-world traffic. The author explains how these empirical traffic studies have led to the three-phase traffic theory and why this new theory is in conflict with standard traffic theories developed before. Moreover, he presents the reason for the failure of applications of standard traffic theories in real-world traffic and discusses why understanding real traffic has caused a paradigm shift in traffic and transportation science. The book examines why understanding real traffic breakdown is the basis for an explanation for the autonomous driving effects on traffic flow. It shows that understanding real traffic is possible from real-world traffic data without the need of mathematical traffic models. This makes the book intuitive for non-specialists, who can qualitatively understand all the basic features of traffic dynamics. In turn, experienced traffic researchers can grasp concepts and ideas made here easily accessible by the author, one of the leading pioneers in the field of vehicular traffic.

Book Description
Traffic Planning and Engineering, Second Edition takes into account underlying trends in traffic planning and engineering. In this edition, Chapter 3 has been remodeled, focusing on the techniques on conducting surveys and their subsequent analysis. Further emphasis has also been provided on environmental management and the central role of computers in all aspects of traffic planning and engineering. The topics discussed in this book include administration and planning in traffic engineering; traffic studies; traffic surveys and analysis; parking; traffic and environmental management; and road user, the vehicle and the road. The traffic stream and capacity; traffic control systems; street lighting, traffic signs, and carriageway markings; and accidents and road safety are also deliberated in this text. This publication is valuable to traffic engineering students, as well as individuals researching on techniques to achieve the safe and efficient movement of people and goods on roadways.

Book Description
This textbook provides a comprehensive and instructive coverage of vehicular traffic flow dynamics and modeling. It makes this fascinating interdisciplinary topic, which to date was only documented in parts by specialized monographs, accessible to a broad readership. Numerous figures and problems with solutions help the reader to quickly understand and practice the presented concepts. This book is targeted at students of physics and traffic engineering and, more generally, also at students and professionals in computer science, mathematics, and interdisciplinary topics. It also offers material for project work in programming and simulation at college and university level. The main part, after presenting different categories of traffic data, is devoted to a mathematical description of the dynamics of traffic flow, covering macroscopic models which describe traffic in terms of density, as well as microscopic many-particle models in which each particle corresponds to a vehicle and its driver. Focus chapters on traffic instabilities and model calibration/validation present these topics in a novel and systematic way. Finally, the theoretical framework is shown at work in selected applications such as traffic-state and travel-time estimation, intelligent transportation systems, traffic operations management, and a detailed physics-based model for fuel consumption and emissions.

Book Description
Road space is shared by multiple vehicles (i.e. cars, taxis, buses, trucks, motorcycles, and mopeds), pedestrians, animals and many other categories of travellers. Easy availability of motor vehicles and advancements in their technology has made road travel easy; on the other hand, this has also resulted in a significant increase in the number of motor vehicle related injuries. Road traffic related injuries remain an important public health problem globally. It has been estimated that approximately 1.25 million people succumb to road traffic injuries annually worldwide, and between 20 and 50 million people sustain non-fatal injuries. It is a cause of great concern that 59% of the severely injured population is young adults aged between the age of 15 and 44 years. At present, globally road traffic injuries are ranked as the eighth leading cause of mortality, and if the current trends continues, it is expected to be the seventh leading cause of mortality at the global level by 2030. Road traffic safety is one of the most significant concerns of the United Nations and a 5-tiered approach has been proposed to combat traffic accidents and fatalities. This includes improvements in health care services focusing on injury care, road safety management, road network safety, vehicular safety, and implementation of road safety legislation. Changes in practices like speed control, use of seatbelts and helmets, respecting traffic signals and signs, avoiding drunken driving (or use of drugs), following traffic rules (lane driving) and avoiding mobile phones while driving are some of the behavioural changes that can bring about a significant reduction in the number of road traffic related injuries. The present book consists of fifteen chapters related to various aspects concerning road traffic and safety, including epidemiology of road traffic injuries, occupant protection and safety devices, risk factors, a manual of safety measures, road safety in hilly terrain and conflict zones, prevention of head injuries, the role of alcohol and bicycle related injuries. The authors hope that the book shall help the readers to get an overview of various aspects related to global road traffic and safety.

Book Description
Measuring Road Safety Using Surrogate Events provides researchers and practitioners with the tools they need to quickly and effectively measure traffic safety. As traditional crash-based safety analyses are being undermined by today’s growing use of intelligent vehicular and road safety technologies, crash surrogates--or near misses--can be more effectively used to measure the future risk of crashes. This book advances the idea of using these near-crash techniques to deliver quicker and more adequate measurements of safety. It explores the relationships between traffic conflicts and crashes using an extrapolation of observed events rather than post-crash data, which is significantly slower to obtain. Readers will find sound estimation methods based on rigorous scientific principles, offering compelling new tools to better equip researchers to understand road safety and its factors. Consolidates the latest updates/ideas from disparate places into a single resource Establishes a consistent use of key terms, definitions and concepts to help codify this emerging field Contains numerous application-oriented case studies throughout Includes learning aids, such as chapter objectives, a glossary, and links to data used in examples
