Abstract
A method for determining a transportation mode acquires motion data and speed data from a mobile device, correlates the motion data to the speed data in groupings, and performs spectral analysis on the groups of motion data. Energy calculated for each of a set of frequency components obtained from the spectral analysis is compared to a baseline value to generate a difference, and a transportation mode type is assigned to the vehicle based on the difference.
