Abstract: Systems and methods herein enable a mobile device to detect that a user is traveling in association with a vehicle based at least on motion data. In some embodiments accelerometer data is used. Motion data is leveraged in combination with various observations regarding vehicular movement to determine whether or not a mobile device is located in or on the vehicle. For instance before entering the state of vehicular movement it can be determined that the user is first in a walking state (e.g. walking to the car bus etc. and entering it). Likewise after exiting the state of vehicular movement the user re enters the walking state (e.g. after stepping out of the car bus etc. the user again begins walking). Further it can be determined that when the user is in the walking state the accelerometer signals appear different to any accelerometer signals seen in the vehicular movement state.
