The dynamics of modal shifts in (sub)urban commuting: An empirical analysis based on practice theories

A modal shift away from the private car onto low-carbon transport modes is an essential part of decarbonising the transport sector. The dynamics of modal shifts are, however, not yet well understood. In particular the interrelations between structural and individual dynamics require further investigation. Furthermore, a better understanding is needed of how new transport modes become integrated into existing mobility practices. In this article, we address these questions in a qualitative study of modal shifts in (sub)urban commuting in three major Swiss cities. We analysed the interview data by means of a qualitative content analysis informed by practice theories. We found that modal shifts can arise i) from dynamics related to the conditions of use of different transport modes, ii) the coordination of everyday mobility with other people, iii) the coordination of resources between different daily practices, and iv) from dynamics related to the intrinsic motivation of everyday mobility. We found that these different dynamics are intertwined and that to understand how modal shifts arise, they must be analysed conjointly, rather than in isolation. And we identified three patterns in how modal shifts play out, and which describe different ways in which the new transport mode becomes integrated into everyday mobility practices. The first pattern describes modal shifts which require no adaptation of existing commuting practices. The second pattern describes modal shifts after which a new everyday mobility routine must be built. And the third pattern describes modal shifts that coincide with a lifestyle change. We conclude by discussing the implications of our findings for decarbonising everyday mobility. •Proposes to study modal shifts in commuting in multi-modal urban environments.•Identifies the dynamics which give rise to modal shifts in everyday mobility.•Identifies patterns in how new transport modes are integrated into everyday mobility.•Illustrates the entanglement of individual and structural dynamics in modal shifts.•Shows that modal shifts can, but do not have to, disrupt commuting practices.
