The invention discloses a transaction method of eliminating adjacent lane interference, applied to an equidirectional multiple lane system. Each lane is correspondingly provided with a road-side unit (RSU) used for wireless communication with an on board unit (OBU); the coverage areas of a plurality of RSUs share overlapped parts. The method comprises: synchronizing the time sequence of the plurality of RSUs, and configuring the emission parameters of the plurality of RSUs to be same; according to the time sequence, the plurality of RSUs simultaneously issuing transaction commands, the contents of transaction commands being set according to the current transaction step of each RSU; and the RSU receiving the feedback signal of the OBU completing the current transaction step with the OBU. According to the invention, the OBU can not transact in the overlapped parts of the RSUs, so that the RSU of a lane can not transact with the OBU of a nearby lane, thereby completely eliminating lane interference.
