THE DIFFERENCE BETWEEN AGE AND AGEING FOR PUBLIC TRANSPORT POLICY: AN APPLICATION OF LONGITUDINAL ANALYSIS

摘要: Consider the simple and surely unchallengeable proposition that people change their travel behaviour over a period of time. Whenever statistical photograph is taken this behaviour, there must therefore be some members sample who are caught, as it were, in middle process change. Any mathematical or intuitive model which seeks to explain observed by reference only conditions obtaining at time will introducing an error, may bias. Longitudinal, dynamic, analysis useful extent enables analyst discover features change, concealed static data sets. In paper authors outline general considerations longitudinal analysis, apply approach ageing its implications for public transport use. The choice specific example made theoretical practical reasons.
