Book Description
Adverse weather has a direct effect on traffic congestion and the time delay on roads. Weather conditions today are changing rapidly and are more likely to have a severe effect on traffic in the future. Although different measures have been taken to mitigate these conditions, it is important to study the impact of these events on road conditions and traffic flow. For example, the surface of a road is affected by snow, compacted snow and ice. The objective of this thesis is to characterize the effect of road surface conditions on traffic flow. To date, traffic flow under adverse weather conditions has not been characterized. A macroscopic traffic flow model based on the transition velocity distribution is proposed which characterizes traffic behavior during traffic alignment under adverse weather conditions. The model proposed realistically characterizes the traffic flow based on snow, compacted snow, and ice. Results are presented which show that this model provides a more accurate characterization of traffic flow behavior than the well known Payne-Whitham model.

Book Description
Weather has broad and significant effects on the roadway environment. Snow, rain, fog, ice, freezing rain, and other weather conditions can impair the ability of drivers to operate their vehicles safely, significantly reduce roadway capacity, and dramatically increase travel times. Multiple roadway activities, from roadway maintenance and construction to shipping, transit, and police operations, are directly affected by inclement weather. Some road weather information is available to users currently, however a disconnect remains between current research and operations, and additional research could yield important safety and economic improvements for roadway users. Meteorology, roadway technology, and vehicle systems have evolved to the point where users could be provided with better road weather information through modern information technologies. The combination of these technologies has the potential to significantly increase the efficiency of roadway operations, road capacity, and road safety. Where the Weather Meets the Road provides a roadmap for moving these concepts to reality.

Book Description
This book is focused on the analysis and modelling of resilience, robustness, and vulnerability of transport systems and their complement: reliability. It provides an elaboration on their generic concepts, analysing disruptive events and nature of their impacts. It also offers an analysis and modelling of the system performances and their indicators relevant for the main actors involved. Applications of the models of performances and their resilience, robustness, and vulnerability to the selected cases of road, rail, air, and maritime transport mode affected by different internal and external disruptive events are also presented. By offering readers a systematic and comprehensive way of dealing with the topic of resilience, robustness, and vulnerability of transport systems and their complement, reliability, this book will be of interest to researchers and professionals alike within the transport industry.

Book Description
Weather and Society: Toward Integrated Approaches provides the first interdisciplinary approach to the subject of weather and society. This guide to the evolving set of problem-solving approaches to weather’s societal issues successfully integrates social science’s techniques, concepts and methodologies into meteorological research and practice. Drawing especially on the work of the WAS*IS workshops (Weather and Society * Integrated Studies), this important reference offers a framework for starting to understand how the consideration of societal impacts can enhance the scientific disciplines that address the scope and impacts of weather, particularly meteorology. Filled with tools, concepts, case studies and helpful exercises, this resource: Lays the groundwork for conducting interdisciplinary work by learning new strategies and addressing typical challenges Identifies leaders of the movement to integrate social science and meteorology and highlights their contributions Includes discussion of such tools as Geographic Information Systems, survey design, focus groups, participatory research and interviewing techniques and concepts Reveals effective integrated research and applications though real-world examples in a global context Helps to identify ways to pursue research, application, and educational opportunities for integrated weather-society work Weather and Society is a hands-on guide for academics, students and professionals that offers a new approach to the successful integration of social science concepts and methodologies into the fabric of meteorological research and practice.

Book Description
Travel is an essential part of everyday life and today most journeys are multimodal. It is the total travel experience that counts and integrated transport must reduce the inconvenience of transfers between modes. Most research and many publications on transport policy advocate sustainable transport, but the priority given to integration has been negligible. Yet integration is one of the most important means to advance sustainable transport and sustainability more generally. While integrated transport systems are seen to be an ideal, there is a failure to make the transition from policy to practice. The authors argue that the achievement of sustainable transport is still a dream, as an integrated transport policy is a prerequisite for a sustainable transport system. It is only when the two concepts of sustainability and integration operate in the same direction and in a positive way that real progress can be made. In this book, transportation experts from across the world have addressed the questions about what is integration, why is it so important and why is it so hard to achieve? The book provides an in-depth analysis of these issues and it aims to provide a better understanding of the subject, about what should be strived for, about what is realistic to expect, and about how to move forward towards a more integrated provision of transport infrastructure, services and management.
