This paper describes a theoretical framework for the analysis of the reliability of a transportation system, to minimise the socio-economic impactsof system degradation. The framework is based upon reliability engineering concepts and techniques in widespread use in the design and management of telecommunication and computer networks. It is argued that with the increasing importance of reliability in transport, these concepts and techniques should, after appropriate modification, be applied to the design and management of transportation systems. The paper describes a mathematical model, which allows for varying levels of system degradation and enables assessment of a wide range of management options, both preventive and remedial. The model, which is based on both traffic and market equilibrium principles, has a unique solution. Also described is a reliability model andalgorithm for obtaining an interval estimate of the reliability of a transportation system. The data requirement for application of the model is slightly more than for strategic transportation planning. A sensitivity analysis technique for identifying the critical components in a transportation system, to guide data collection and the design of measures to improve transportation system reliability, is also described.
