| Summary: | In this paper, the results of safety analysis in roundabouts, unsignalized intersections, which are widely spread, and practical methods to avoid collision accidents or conflicts are presented. First, possible collision types (scenarios) were distinguished in roundabout with recent accident data and safety characteristics for three roundabouts of different structures were analyzed using video image processing methods. Through the analysis process, conflict events were identified one by one to classify criteria, and a method for evaluating the safety of the target roundabout was proposed. In addition, a self-driving method based on a car-mounted (black box) camera was proposed. This may be applicable to the implementation of Intersection-Advanced Driver Assistance System (I-ADAS) by providing the driver with safety-related information regarding entry into the roundabout.
