Purpose-The chapter provides a general review of the policy debate around the provision of formal Park-and-Ride (P&R) facilities and the empirical research evidence about travellers’ responses to the opportunities they present, drawing on evidence from the United Kingdom and the Netherlands. The effects of the schemes on road traffic and car dependence are considered. Design/methodology/approach-The different ways in which private vehicles and public transport are combined during journeys are reviewed. The position of P&R is considered as a modal variant within a ‘sociotechnical system’ competing with the more established journey options of fully private and fully public transport. Scenarios which can maximise the traffic reduction and sustainable development potential of P&R are examined. Findings-The review of the policy context establishes that a range of policy objectives are conceived for P&R depending on different professional and citizen perspectives. There is partial understanding amongst local authorities about the effectiveness with which P&R addresses the range of objectives in practice. The key travel behavioural findings are that only a portion of P&R users’ car trips are shortened. Hence, overall increases in car use occur, combined with overall reductions in public transport use, and in some cases less active travel. Where dedicated public transport services are operated, these are also a further source of additional traffic. Practical implications-P&R implementations are generally successful where they are explicitly for providing more parking for economic growth or traffic management reasons, rather than to enhance sustainable mobility. The essential conditions for traffic reduction to occur in future are a strategic subregional integrated parking and public transport strategy which achieves interception of car trips early and ensures public transport services remain attractive for a range of access modes. Originality/value-The chapter provides a synthesis of work by a number of leading authors on the topic and includes elements of originality in the combination of the established knowledge, the addition of novel insights, and in overall interpretation.
