Shared micro-mobility services are rapidly expanding yet little is known about travel behaviour. Understanding mode choice, in particular, is quintessential for incorporating micro-mobility into transport simulations in order to enable effective transport planning. We contribute by collecting a large dataset with matching GPS tracks, booking data and survey data for more than 500 travellers, and by estimating a first choice model between eight transport modes, including shared e-scooters, shared e-bikes, personal e-scooters and personal e-bikes.

Key findings



Trip distance, precipitation and access distance are fundamental to micro-mobility mode choice. Users are willing to walk between ~ 60 m and ~ 200 m to access shared e-scooters and shared e-bikes, respectively.

‍



Substitution patterns reveal that personal e-scooters and e-bikes emit less CO2 than the transport modes they replace, while shared e-scooters and e-bikes emit more CO2 than the transport modes they replace.

While shared e-bikes and e-scooters might increase CO2 emissions in the short-term,they could help spark sustainablemobility transitions in the long-termif usage leads to ownership.
