摘要

For last several years, the number of pedestrian fatalities due to traffic accident is over 2,000 in Korea. The portion of pedestrian fatalities in total traffic fatalities reached about 40%. In this reason, it is important to introduce effective and aggressive policies which can reduce pedestrian traffic accidents. To do this, it is necessary to understand of actual situation and characteristics of pedestrian accidents. In this study, it is assessed that potential of in-vehicle real accident videos which can be used to analysis of pedestrian accidents. In-vehicle real accident videos used in this study contain real situation about collision. In this study, we used the in-vehicle real accident videos recorded by car black-box in taxis. In-vehicle blackboxes (dashboard cameras) which recorded accident situation were installed in taxis in Incheon city. Therefore, analyzed accident videos are about car-pedestrian traffic accidents between taxis and pedestrians. Total 252 car-pedestrian accidents or car-bicycle accidents videos in 2010 were used. All videos contain the situation of accidents about between taxis and pedestrian or bicycle. 25 accidents videos are about children, 202 videos are about adults, and 25 videos are about elderly people. In-vehicle real accident videos have a potential to explain several characteristics of accident such as violations of driver or pedestrian, car speed, causes of poor visibility of a car driver, and so on. Furthermore, the eye direction of pedestrians could be checked using accident videos. As a result of analysis, the ratio of pedestrians who looked taxi before collision is only 29%. It has decreased with higher car speed, bad weather conditions, car violation speed limit. Average duration between sudden appearance of pedestrian and collision is only 2.6 seconds. We thought that this duration is not enough time to dodge collision when considering drivers PIEV time. Duration has been decreased when taxi have darkness, high car speed, poor visibility. Car-pedestrian accidents are very dangerous because collided pedestrian could be serious injury or fatality. However, it is not easy to understand the exact situation when car-pedestrian collision was occurred. In this study, in-vehicle real accident videos which recorded situation of collision are used. Accident videos have important information about collision time of accident. Through this study, we can find that In-vehicle real accident videos have potential to analyze of pedestrian accidents. Using accident videos, many characteristics of traffic accident can be explained. Nevertheless, it should be pointed that accident videos are not enough to analysis various cases of accident. Since in-vehicle dashboard cameras installed in vehicles are increasing, more accident videos will be archived in the future.
