This book focuses on clean transport and mobility essential to the modern world. It discusses internal combustion engines (ICEs) and alternatives like battery electric vehicles (BEVs) which are growing fast. Alternatives to ICEs start from a very low base and face formidable environmental, material availability, and economic challenges to unlimited and rapid growth. Hence ICEs will continue to be the main power source for transport for decades to come and have to be continuously improved to improve transport sustainability. The book highlights the need to assess proposed changes in the existing transport system on a life cycle basis. The volume includes chapters discussing the challenges faced by ICEs as well as chapters on novel fuels and fuel/ engine interactions which help in this quest to improve the efficiency of ICE and reduce exhaust pollutants. This book will be of interest to those in academia and industry alike.

This book discusses the role of mobile network data in urban informatics, particularly how mobile network data is utilized in the mobility context, where approaches, models, and systems are developed for understanding travel behavior. The objectives of this book are thus to evaluate the extent to which mobile network data reflects travel behavior and to develop guidelines on how to best use such data to understand and model travel behavior. To achieve these objectives, the book attempts to evaluate the strengths and weaknesses of this data source for urban informatics and its applicability to the development and implementation of travel behavior models through a series of the authors' research studies. Traditionally, survey-based information is used as an input for travel demand models that predict future travel behavior and transportation needs. A survey-based approach is however costly and time-consuming, and hence its information can be dated and limited to a particular region. Mobile network data thus emerges as a promising alternative data source that is massive in both cross-sectional and longitudinal perspectives, and one that provides both broader geographic coverage of travelers and longer-term travel behavior observation. The two most common types of travel demand model that have played an essential role in managing and planning for transportation systems are four-step models and activity-based models. The book's chapters are structured on the basis of these travel demand models in order to provide researchers and practitioners with an understanding of urban informatics and the important role that mobile network data plays in advancing the state of the art from the perspectives of travel behavior research.

This book investigates Unmanned Aircraft Systems (UAS) with a payload capacity of one metric ton for transportation. The authors provide a large variety of perspectives-from economics to technical realization. With the focus on such heavy-lift cargo UAS, the authors consider recently established methods for approval and certification, which they expect to be disruptive for unmanned aviation. In particular, the Specific Operations Risk Assessment (SORA) and its impact on the presented technological solutions and operational concepts are studied. Starting with the assumption of an operation over sparsely populated areas and below common air traffic, diverse measures to further reduce operational risks are proposed. Operational concepts derived from logistics use-cases set the context for an in-depth analysis including aircraft and system design, safe autonomy as well as airspace integration and datalinks. Results from simulations and technology demonstrations are presented as a proof of concept for solutions proposed in this book.

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.

Over the past two decades, society has been witnessing how technological, political, and societal changes have been transforming individual and collective urban mobility. Driven both by newcomers and traditional players, by disruptive as well as incremental innovations, the main objective now is to enhance mobility and accessibility while, reducing vehicle ownership, congestion, road accidents, and pollution in cities. This transformation has been mainly enabled by the widespread adoption of internet-connected devices (e.g.: smartphones and tablets) and by the innovative business models, technologies, and use-cases that arose from this rapid digitalization, such as peer-to-peer, and two-sided markets providing several mobility schemes: car-sharing, car-pooling, bike sharing, free-floating (cars, bikes, electric scooter), ridesharing and ride hailing either for long distances as well as for urban and micro-mobility. The book presents - in a holistic perspective - how this revolution is happening and what are the major cornerstones for the implementation of robomobility. It aims at answering several substantial issues, such as: What is robomobility and what does it imply for the different stakeholders of the public transport ecosystem? How do policy makers integrate this innovation and how ready the regulations are? How do citizens take part in this transformation? What is the level of user acceptance for this new type of mobility? What are its environmental impacts? What is the economic impact of deploying these shuttles in a local ecosystem?

This book supports companies in the transport sector, political decision-makers, transport engineers, planners and scientists doing fundamental research who are confronted by growing challenges in transport. These challenges arise from a number of powerful socio-technical trends, including: digitalisation, globalisation, urbanisation, and the requirements of individual users and the increased need to reduce environmental impact of transport. Providing the innovations required to cope with these challenges is not a simple matter. Towards Innovative Transport Systems structures and compiles theoretical foundations from evolutionary economics, the sociology of technology and innovation research in a way that provides a broad understanding of innovation processes without demanding prior knowledge. Using the Concept of Transport System Evolution (CTSE), it explains in depth the economics of innovation in the transport sector, thus contextualising processes, drivers and obstacles at work in current practice; among such processes are the changeover to electric mobility, the realization of autonomous cars, the revival of railway by innovations and dealing with disruptive innovations in transport. The CTSE is an approach to making concrete the multi-level perspective for the transport sector introduced by Frank Geels. On the basis of the CTSE, the author proposes principles for a novel innovation policy in transport that can serve the reader as a guide when making strategic decisions.
