Abstract:

A methodology is presented for analysing panel data for the purpose of measuring changes over time in travel mobility and identifying probable causes for such changes. Mobility is assumed to be a nebulous concept, referring to the general opportunity and ability to move about in satisfying activity needs and desires. The mobility experienced by an individual might be affected by changes in income, the location of residence or workplace, family structure, or the time and money costs of travel. Mobility analyses are central to an understanding of the role of transport in everyday life and should contribute to establishment of improved guidelines for forecasting the consequences of governmental policies.
