VEHICLE TEST SPEEDS FROM VIDEO RECORDINGS

This article describes the method whereby a video camcorder may be used to determine the speed of vehicles when performing testing related to accident reconstruction. Equipment is also readily available to view each individual frame such as to show the location of the vehicle with reference to a fixed vertical rod reference. Thus, with a dimensionally marked banner that is attached to the vehicle, its location with regard to the fixed reference rod can be determined. The distance the vehicle moves between frames can be determined and, knowing the time, the average speed for the very short interval of 1/30 second between frames can be calculated. This system allows the speed to easily be determined to within 0.41 MPH when the recording equipment and tape is calibrated such as to provide frame speeds to within 1/8 frame per second.
