There is an implication in the notion of 'transport policy' that substantial improvements could be made to the transport system given sufficient ingenuity, investment and good will. This paper argues that such policy aspirations cannot cope with the desire for ever-increasing mobility, a deep and powerful force in modern society. In densely populated countries there is no possibility of meeting the demand for unconstrained movement through construction of additional transport infrastructure, since new and longer journeys would quickly fill the extra capacity until the congestion equilibrium is re-established. What limits liability in practice is the time individuals have available for travel, time which is equitably distributed. Transport plans need to acknowledge this time constraint as fundamental, and accordingly be realistically modest about what is achievable. It is an illusion that the transport system could be substantially more efficient whilst remaining equitable. (Author/publisher).
