To provide visible light communication on the roadway.SOLUTION: A visible light communication emitter includes: a first light emitting device configured to emit a flash modulated at a first target frequency in an invisible spectrum; and a second light emitting device configured to emit a flash modulated at a second target frequency in a dedicated invisible spectrum. Difference between the first target frequency and the second target frequency is predetermined.SELECTED DRAWING: Figure 2
