Vehicle Safety in DGIST: Roundabout Warning System

Drivers, who first visit DGIST, cannot easily notice the roundabout at night. It is difficult for the drivers to see the roundabout or a vehicle approaching to the roundabout from other direction. In order to prevent a car accident at night, we propose a warning system that represents the warning light on the roundabout when a vehicle is approaching. To be specific, green LED light is on when only single vehicle is approaching to the roundabout and yellow led light flickers when more than two vehicles are approaching to the roundabout.
