This book argues that the issues surrounding sustainable transport constitute a new – post-modern – phase in transport policy and management. Achieving sustainable transport requires more than »optimal » management of congestion and the effects on public health and the environment. Assessments of external effects, and their optimal levels, tend to be piecemeal, localized, and focused on a specific type of effect. Sustainability, on the other hand, is a comprehensive, forward-looking concept that encompasses the achievement of a state of society that is better overall; it requires a widened concept of welfare that includes environmental quality and social justice in both the short and long term. This book is organized into three sections, each discussing a major set of challenges to the transition to a sustainable transport system.
