Abstract
A vehicle can include an on-board data processing system that receives velocity data captured by one or more sensors of the vehicle. As a vehicle travels along a route, the on-board data processing system can process the velocity data to identify potential vehicle stops. For example, the system can detect a trough in velocity values, and determine whether a velocity value at the trough is below a threshold velocity value. If the velocity value is below the threshold velocity value, the system can determine whether any vehicle stops were previously detected within a threshold time of the time corresponding to the trough. If a vehicle stop was previously detected, the system may detect that a stop occurred at the time of the trough if the velocity of the vehicle increased by at least a velocity ripple value between the time of the previously-detected stop and the time of the trough.
