The present research analyses the impact of individual time and money budgets to mobility growth. The total activity pattern is analysed and a theory on activity behaviour is constructed. From this theory, a strategic mathematical model is formulated for the allocation of time and money to activities, including travel, and goods. Due to the lack of combined data on time and money expenditures, the model is estimated on Dutch Time use data of 1980, 1985, and 1990. Scenario analyses explore extreme developments in travel time expenditure in order to examine whether limits to mobility growth exist. The results are compared with other forecasts. This dissertation shows that if travel speeds can be managed in the future, mobility growth will reach limits.
