NEW USES FOR OLD TRAVEL DATA

The basic requirement for good planning is reliable information. As planning emphasizes change, previous information is often discarded. In the case of travel data this abandonment is premature. This paper demonstrates that existing travel data are still extremely valuable for at least three distinguishable, and increasingly important, planning tasks. First, for the prediction of how individuals will react to specific policies, such as rising fuel prices or lower public transport fares, i.e. For travel demand modelling using individual choice models. It is shown that these models can be satisfactorily estimated using home interview survey data. The technique can be improved by market segmentation based on socio-economic characteristics or on the data itself, by using the travel section to partition the travellers into sets who really have a travel choice. Second, for the analysis of the existing urban public transport systems' performance, i.e. Who is using public transport, when and for what purposes. Third, for the analysis of individual's activity patterns and how these vary with the socio-economic and demographic characteristics of the individual (A). (TRRL)
