Op zoek naar grenzen aan de mobiliteitsgroei

The steady ongoing growth of mobility raises the question whether this growth will continue unaltered or whether there exists a limit to this growth. One may theoretically assume the last, under the assumption of limited time and money budgets, because mobility requires time and money expenditure. Presuming this is correct, it is interesting to predict when this limit will be reached and whether this can be foreseen. This paper formulates a theory describing the allocation of time and money to activities and travel. This theory, based partly on literature survey and empirical findings, assumes the theory of utility maximisation under flexible budget constraints. In this theory undertaking an activity leads to a positive contribution to utility, which depends on type, duration, and location of the activity. The paper concludes with a first development of a model that can carry out long term future explorations at a strategic level.
