A Study on Traffic Incident Detection Using Sensing Information from Roadside Infrastructure

In order to help to reduce traffic accidents, it is important to identify, analyze, and find the hidden causes of traffic accidents. In this study, attention is paid to the traffic incidents at intersections. In Japan, about 55 percent of the traffic accidents have happened at intersections. The sensors on the roadside infrastructure have an ability to detect the position, shape, and the speed of each vehicle accurately from the bird’s eye view. The overcrowded intersection, however, adds unpredictable errors onto sensing information. This paper proposes the traffic incident detection method based on the speed estimation with the unpredictable error tolerance against disturbance. Moreover, the effectiveness of the proposed method is verified through the simulation study. The potential variations of the observed speed data are generated by adding the observational errors, which are simulated by randomly sampling the error distributions using the normal distribution, to the actual speed data of the real accidents.
