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.

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.

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.

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.
