The activity space concept is used to capture the structures of the observed locational choices of individual travellers. It represents the distribution of places visited over a period of time and measures the space which contains those places. Among other, the preferred continuous representation was the 95% confidence ellipse – a methodology originally applied to home range studies in habitat research.<br/>As this approach faces difficulties in terms of a realistic description of human space usage it is believed that activity spaces could be eventually better represented by other geometries. This paper deals with the further development of activity space concept and especially focussing on the minimisation of its area. Several geometries have been explored including ellipses, superellipses, bean curves and Cassini ovals Show more
