Abstract
A lane change detecting system includes an emission unit for emitting a predetermined signal, the emission unit being provided in a boundary between lanes of a road so that the predetermined signal emitted by the emission unit is affected by a mobile body which crosses the boundary between the lanes, a receiving unit which is provided in the boundary between the lanes for receiving the predetermined signal emitted by the emission unit and outputting a receiving signal corresponding to the received signal, and a determination unit for determining, based on a state of the receiving signal from the receiving unit, whether a mobile body crossed across the boundary between the lanes.
