The reliability of transportation networks has become an increasingly important issue as sustained economic growth and improvements to the quality of life around the world lead to increases in the value of time. Consequently, schedules and routes need to be able to accommodate the unexpected, like accidents, disasters or traffic flow fluctuations, with as little loss in operational efficiency as possible. Sources of unreliability include variation of demand and supply. It is widely expected that network reliability analysis will play a more important role in the planning, design and management of transportation facilities and networks in the future. This book is an outcome of the First International Symposium on Transport Network Reliability (INSTR), held at Kyoto in 2001, and consists of 24 selected papers. It covers various aspects of transport network reliability, such as definitions and methodological developments for reliability indices, behavioural analysis under uncertainty, evaluation methods for the disaster resistance of transport networks, and simulation/observation of travel time reliability.

The fabric of all societies is held together by networks of various kinds, such as water supply, energy supply, sewage disposal, communication and, perhaps most importantly, transportation. "Transportation Network Analysis" is concerned primarily with the spatial, but also the temporal, nature of the movement of people and freight across land, where the movement is channelled onto roads or railways. The road and rail infrastructure constitute the transportation network while the movement of people and freight constitute the flows on the network. Providing a coherent theoretical framework, this book focuses on three interdependent aspects of transportation networks: state estimation the estimation of path flows, vehicle queues, stops and delays; route choice link cost functions and the equilibrium principle; and network design traffic signal control, link design and link insertion or deletion. While the treatment of transportation networks is general and not specific to one mode of transport, the emphasis is on private transport by road networks with extensions to public transport indicated where appropriate. Numerous examples illustrate both definitions and algorithms.
