Life course changes in travel mode use with partner interactions

Abstract

The paper links two strands of research on travel behaviour, i.e. the mobility biographies literature and the literature on intra-household interactions in travel. It studies changes in car use from one year to the next as a function of life events (namely the birth of a first-order or higher-order child), changes in household worksharing with respect to paid and unpaid work, and trip patterns. In doing so, it does not only take into account changes in the respondents' variables, but also changes in partner variables. The analysis focuses on dual-licenced couple households sharing a car. This is based on the expectation that changes in mode use are most likely among those who share a car and, thus, may need to renegotiate car access when change occurs. The data used is the German Mobility Panel 2004 to 2016. At the time of submission this is work in progress. Hence, results are not yet available. Interim results suggest that multiple interactions between partners can be observed.
