The invention provides a method and system for extracting OD locations of a vehicle on an expressway. The method includes: acquiring mobile phone signaling data and license plate recognition data; preprocessing the signaling data and recognition data; segmenting mobile phone signaling data trajectories to obtain signaling data with a travel order; matching the mobile phone signaling data trajectories against license plate recognition data trajectories, to obtain a vehicle and a mobile phone signaling user corresponding to the vehicle; and extracting a passing time of the vehicle passing through a road section in the license plate recognition data, calculating time differences between the passing time and travel trajectory points of the mobile phone signaling user corresponding to the vehicle, and taking start and end locations of a travel order of mobile phone signaling data in which a minimum time difference is located as OD of a current travel of the vehicle.
