Abstract
The purpose of this paper is to offer comment and reflections based upon experience gained in the development and application of two very different panel studies in the field of travel demand analysis. These experiences are now being applied in the design of a third (as yet unreported) panel research project which is currently under development. All three panels are within the field of transportation but reflect widely differing policy and research objectives. The comments offered are based on personal experience and are hopefully useful but anecdotal in nature. They do not pretend to be in-depth considerations of the subjects treated. However, wherever possible reference has been made to literature which offers greater depth and guidance.
