Abstract
In a road stud system, a road stud includes a terminal storage unit, a light emission unit, and a radio communication unit. The light emission unit emits a light having a first color tone or a second color tone in a first or second direction. The radio communication unit receives an instruction signal for an operation of the light emission unit. A control system that controls a plurality of road studs includes a determination unit and an instruction unit. The determination unit determines whether an overlapping area is in a first state in which passage of a pedestrian is prioritized or a second state in which passage of an automobile is prioritized. The instruction unit sends an instruction signal, in accordance with the result of the determination, regarding the direction of the light emission and the color tone to each of the road studs.
