abstract="This paper uses a unique multi-day multi-wave panel data set of households, and their travel to analyse the influence of life events and travel behaviour. We focus on the travel time stability of individuals participating in five or more waves of data collection. This reflects the broader use of GPS devices. The popularity of mobile devices offers greater low-cost opportunities for collecting detailed travel data records, and may lead to opportunities to analyse how life events impact upon travel behaviour. This paper also focuses on a range of issues that we expect will be important for research that uses longitudinal data sets.<p />",
