The present study was intended for investigating some factors of the traffic accident. The major part of the accident arose from the driver's carelessness. On the factor of the traffic accident, following two factors were in the top level : against the safety speed and the driving under the influence of wine. The speed control in the driving is operated by the speed indicator. Therefore, it is impossible to watch the speed indicator carefully and repeatedly. During the driving, the driver should watch on the road, at the signals, pedesstrains and other motor vehicles. Then, the speed-feeling which obtained by the past experience was examined. The speed-feeling would be depended on the compound sensation including the visual, the acoustic sensation, the sense of the equilibrum, the sense of the movement and the autneus sensation. The three points were examined : (1) Dial operation, (2) Oral estimation and (3) with eye bandage estimation. Following results were obtained : 1. The error extent in the speed-estimation was + or - 10km/h. 2. The over and under-estimate was depended on the initial speed. 3. The velocity appreciation was influenced by the visual factor. 4. The speed-feeling was influenced by some sensations besides the visual sensation. And it was seemed that the sense of the acceleration in the labyrinth would not be disregared.
