Travel surveys are fundamental for travel research and policy development: the results are used to monitor trends and explain (changes in) travel behavior. Data are traditionally collected using questionnaires and travel diaries that can be completed online, on paper, via telephone or via face-to-face interviews. During the last decades other data collection methods have been developed, mainly in order to reduce costs of the data collection process and to improve quality of the resulting data.
In The Netherlands, an innovation program is set up to explore innovations of the existing National travel survey called OViN (Smit et al, 2016). Part of this program is the exploration of new data collection methods. Several methods have been explored in the innovation program and the current focus is on the use of GPS loggers and smartphones. There has been a lot of research on these data collection methods, see for example the comprehensive overview given by Lee et al. (2016). The research varies from theoretical improvements of, for example, imputation algorithms to practical tests of the feasibility of the data collection methods.
Despite all the research in this area it is still not easy to assess the usefulness of GPS loggers and smartphones for the Dutch national travel survey. Therefore, as part of the innovation program, we will look for lessons learned from practical applications of GPS loggers and smartphones in other travel studies. On top of that, we will also carry out a practical test using GPS loggers specifically for the Dutch survey.
The paper will summarize these practical experiences from large-scale practical tests. This includes both tests that are already performed in and outside Europe and the practical test for the Dutch survey. We will look for information that could help assessing the usefulness of GPS loggers and smartphones for the Dutch national travel survey. Therefore, we will mainly look for reasons (not) to use GPS loggers and smartphones in other travel surveys and discuss impacts on costs and quality. Furthermore, we will look at the practical aspects like response rates, sampling size, contact with respondents, incentive structures, and distribution of necessary materials if applicable.
