The main objectives are: to identify the factors which affect travel time budgets amongst the individuals and groups comprising a population, to assess whether any secular trend may be expected and to assess the implications of future demographic changes.
An outline will be prepared on how the travel time budget concept and data might be incorporated into transport scheme appraisal, modelling and planning in order to address the implications of constant travel time budgets for the main elements of transport and land use planning policy and the relationship between the two.
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. However, there is increasing evidence that such policy aspirations cannot cope with the desire for ever-increasing mobility, a deep and powerful force in modern society. In densely popoulated countries, there seems 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 congestion equilibrium is re-established. What limits mobility in practice is the time individuals have available for travel. Transport plans need to acknowledge this time constraint as fundamental.
The project will review the relevant literature and gather and analyse the appropriate data. The findings will be synthesised into a coherent report.
