This book deals with the estimation of travel time in a very comprehensive and exhaustive way. Travel time information is and will continue to be one key indicator of the quality of service of a road network and a highly valued knowledge for drivers. Moreover, travel times are key inputs for comprehensive traffic management systems. All the above-mentioned aspects are covered in this book. The first chapters expound on the different types of travel time information that traffic management centers work with, their estimation, their utility and their dissemination. They also remark those aspects in which this information should be improved, especially considering future cooperative driving environments.Next, the book introduces and validates two new methodologies designed to improve current travel time information systems, which additionally have a high degree of applicability: since they use data from widely disseminated sources, they could be immediately implemented by many administrations without the need for large investments. Finally, travel times are addressed in the context of dynamic traffic management systems. The evolution of these systems in parallel with technological and communication advancements is thoroughly discussed. Special attention is paid to data analytics and models, including data-driven approaches, aimed at understanding and predicting travel patterns in urban scenarios. Additionally, the role of dynamic origin-to-destination matrices in these schemes is analyzed in detail.

This book describes the development of an innovative solution for electrified roadway pavements based on engineered cementitious composites, which are exhibiting an extreme tensile strain capacity that is much higher than conventional concrete. This enables the pavement to work without steel reinforcement and to embed a dynamic wireless power transfer technology for charging electric vehicles. At first, the book presents a modified performance-driven design approach to improve the composites to achieve the optimum pavement design in terms of functional and structural performance. It shows that the modified composites can be used to fulfil the safety and comfort factors without neglecting the characteristics of conventional ones. Further, 3D finite element and fluid dynamics models are used to analyse the pavement properties. The validated models can predict the functional performance, including skid resistance, surface water drainage, and noise. In the remaining part of the thesis, an environmentally-friendly photocatalytic function for pavement made of engineered cementitious composites is investigated. In turn, a multi-criteria design analysis is proposed to identify the optimum functional performance of the pavements. All in all, this book reports on a comprehensive approach to design, analyse and optimize engineered cementitious composites for electrified road pavement application. A special emphasis is given on applications in Singapore and other tropical megacities.

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.

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.

This book presents commuting as a new paradigm in mobility studies in the context of global south. It delves into suburban train commuting in Eastern India. The book interprets commuting not only as a means to attend work but also as a process producing kinetic event-space infused with different mobile practices, which is not determined by their locational fixity, rather can be cognized. It analyses the role of suburban train commuting in the metropolitan expansion of Kolkata, and the transformation of rural space into urban. The significant contribution of the book lies in explaining commuters' experiencescape and the production of spatial fluidity in time capsule through commuting. It also explores the subjective reality of gendered commuting. The book uses a trans-disciplinary research design, blending quantitative and ethnographic research methods. The area selected for the empirical research is the Howrah-Bardhaman Main Railway Line (108 km), the first suburban railway line in Eastern India. Commuters originating from three adjacent districts of Purba Bardhaman, Hooghly and Howrah took part in this research. Besides the commuters, non-commuting passengers and hawkers in the train were also interviewed to understand the diverse perceptions of the process of commuting. This book may be considered as a reference book for mobility studies, transport studies, urban geography and regional planning.

In this book, a novel agent-based, realistic, and general motion model of pedestrians and (human-driven) vehicles is proposed. It can capture a large variety of interactions and be utilized to assess the applicability of different shared space schemes and in the advent of autonomous vehicles. Sustainable urban traffic and transport is a key to successful future development of our society. Urban traffic is predicted to increase further, and the lack of traffic space makes it undesirable to maintain today's strict separation of different modalities. Shared space design principles promote a flexible use of traffic infrastructure by enabling different traffic modalities to share the same space with few or no explicit regulations. Simulation technologies are becoming an essential tool for traffic planners and managers to analyze future urban areas before new concepts and technologies are applied on the road. The proposed simulation model can suitably replicate the motion behaviors of pedestrians and vehicles from new environments with incremental integration of new behaviors and calibrating model parameters.
