FAMILY CHANGES AND PUBLIC TRANSPORT USE. A DYNAMIC ANALYSIS USING PANEL DATA ---ANALYSES OF PANEL DATA, PROCEEDINGS OF THE ROUND TABLE CONFERENCE ON THE LONGITUDINAL TRAVEL STUDY, THE HAGUE, MAY 14-15, 1987
Panel data are used to investigate what happens when people have some important transitions or change in their life-cycle, employment status, income, or car ownership. Only two years data are available, and the pace of transitions is slow: as a result relevant sample sizes are rather small. It is found that in many cases the effects on mobility are different from what would be expected from cross-section data. In particular: (a) car ownership changes are substantially less than expected; and (b) public transport does not benefit as much as expected when people become members of specific dependent or 'captive' groups. These results indicate that the effects of income growth on car ownership and therefore on public transport may not be as drastic as feared. But on the other hand it may be more difficult for public transport to secure a captive base market than hoped. Both results suggest that policy and marketing strategies may be decisive. The public transport market in two weeks over two years consists of approximately equal proportions of loyal, lost, and new people. There is a slight tendency for the loyal passengers to be those who have not had major transitions in their families, but it is easier to attract new passengers from those who have had such transitions.(a) for the covering abstract of the conference see IRRD 818179.
