1. An adaptive motion sensor system on a transport vehicle, comprising: a vibration sensor; an adaptive threshold component that receives input values based on readings of said vibration sensor, said adaptive threshold component identifying a threshold value such that an input value above said threshold value is indicative of a first active operating state of the transport vehicle and an input value below said threshold value is indicative of a second active operating state of the transport vehicle; and a motion detection component that receives input based on readings of said vibration sensor, said motion detection component determining an operating state of the transport vehicle through an analysis of said received input relative to said identified threshold value.
