Monitoring car use over extended period with GPS devices – retaining response rates and understanding reactions

A study in Melbourne, Australia tested different ways drivers could pay for road usage. A random sample of 1500 drivers carried GPS devices in a selected household vehicle for a nine-month period.The paper investigates response rates over time to a multi-stage survey and shows that although initial response was low, careful design saw high levels of retention. It also discusses the role of focus groups in understanding response and participation. It concludes that robust results can be obtained by analysing people’s understanding of the new regime and demonstrates the advantages and pitfalls of using focus groups in this context.
