This study observed vehicle horn usage on three intersections in Seoul, Korea, to investigate the relationship between horn use and traffic situations, such as traffic flow, composition of vehicle lanes, recording by video camera and writings. Then, we picked up one of those cases, ‘cutting in’, and tried to make a model for it, considering some causes related to vehicle speed, headway, traffic flow and arrangement of intersection. From the investigation, we classified horn usage into some types, ‘Cutting in’, ‘attention’, ‘pressure’, etc., and inferred a couple of causes of the horn use. We resulted that one of the causes is due to the way of using lane for right turn vehicles, another one is due to no match for lanes on inflow and outflow. For modeling, we could gain a statistically significant model including the factors related to vehicle drive, ‘velocity’, ‘distance between vehicles’ etc.
