Evaluating personal travel planning: If it is prohibitively expensive to get a robust answer then what should we do?
AbstractA recurring problem relating to the robust measurement of the impacts of personal travel planning (PTP) is identified, in terms of unrealistic expectations on the part of sponsors and, more generally, a limited understanding of the complexity of statistical inference. A number of pragmatic responses is proposed: practitioners and academics should attempt to spread a better understanding of this complexity; this "community" should also engage those who commission PTP in a debate about the need for monitoring and its purpose; the community should openly accept that PTP is not yet a mature intervention; efforts should be made to convince those who commission PTP to appreciate the value of research conducted to understand PTP's impact as opposed to simply measuring it; and the PTP community should participate more actively in the drive to improve methods used to gauge behavioural change in travel resulting from the intervention.
