## Abstract

An electronic device includes memory circuitry, a wireless interface, and processor circuitry. The processor circuitry is configured to obtain positioning data and movement data from a wireless device. The processor circuitry is configured to determine, based on the positioning data, one or more stops including a first stop of a transportation journey of the wireless device. The processor circuitry is configured to determine, based on movement data associated with the first stop, a transition parameter associated with the first stop. The processor circuitry is configured to determine whether the transition parameter satisfies a first criterion indicative of a change of transportation mode at the first stop. The processor circuitry is configured to output, based on the transition parameter, a transportation parameter.
