The Netherlands Mobility Panel: An innovative design approach for web-based longitudinal travel data collection

This paper introduces a new household panel – ‘The Netherlands Mobility Panel’ (in Dutch: MobiliteitsPanel Nederland MPN). To collect trip and trip stage data for the MPN, we developed a state-of-the-art travel diary, the design philosophy of which will be explained in this paper. Further, the initial assessment results based on the first data collected autumn 2013 is presented, providing insights into the benefits of the travel diary design. We explain how differences in data quality relate to differences in diary design, diary layout, and diary content.
