The method which analyze the pedestrian movement quantitatively by using the digital image processing techniques is discussed in this paper. The results are summarized as follows : 1) The method was developed to measure the position of pedestrians 30 times in every second automatically. The main system of this method, using the fact that the hair is normally darker than the other parts, is to trace the position of hair automatically in the binary image which are made from the videotape recorded the movement of pedestrians. 2) Two experiments on walking in straight path and in L-shaped corner were performed. By using the new method the data of both experiments were processed into the position, the velocity and accelerated velocity of pedestrian. It was found to be effective to get the variation of the accelerated velocity of pedestrian for analyzing the movement.
