Recently, AACN (Advanced Automatic Collision Notification) that presupposed cooperation with emergency life-saving organizations is expected. Therefore, emergency life-saving organizations must recognize injury speciation of patients, as quickly as possible. So, the author tried the traffic accident analyzing method by statistical data analysis from combing analysis items analysis items for main site of injury and analysis items for injury contents (indicated in the traffic accident statistics vote by Japanese National Police Agency). And furthermore it is necessary to improve the safety of vehicles not only for same class collisions but also for collisions between vehicles of different types (e.g., between SUVs and sedans). In this study, the author applied the method of analysis as described above for frontal collision between SUVs and middle sedans, and analyzed using statistical data stored in ITARDA (Institute for Traffic Accident Research and Data Analysis). In the case of fatal or severe injuries, it is shown that the component rate of chest fracture of middle sedan drivers is higher than that of SUVs. It is supposed that the difference in these rates is caused by the vertical offset configuration between the frames of the two different types of vehicles when they crash into each other.

Traffic accidents caused by the pedal operation error by the elderly drivers have become social problem, for example the collision with structure, vehicle or pedestrian. It is generally known that due to the weakening of the flexibility of the elderly's body, the angle at which the knees are placed inside decreases. As the result, in the sitting posture of elderly drivers, there is a difference in the posture of the legs with non-elderly drivers. This may be the hypothesis that it is one of the major causes of the increase in pedal operation errors by them. In this study, we focused attention on the posture of the leg when parking the vehicle with backward movement, and visually checked the sitting posture of the driver's leg and the behavior of the right foot, the driving in simulating the rearward turning motion experimentally verified by twisting the waist of a person. As this check, it is clarified the relationship between the posture of driver's leg or right foot and the foot location area on the brake pedal, which are assumed making effects of pedal operation error.
