The present paper evaluates the pre-collision travel speed of a road vehicle, in the event of a frontal collision with a fixed object such as a pole. In this regard, the method of video recordings and image processing using Tracker software program is used. In order to validate the proposed method, the obtained results are compared to the ones acquired with the use of accelerometers mounted on the inferior surface of the vehicle’s body. These accelerometers provide a series of real data during the time of the crash, which are then processed in order to reduce the anomalies that appear as a consequence of external factors such as vibrations or signal interferences.
