The invention discloses an automatic tidal lane provided with electromagnetic isolation piers. The automatic tidal lane provided with the electromagnetic isolation piers comprises a tidal lane body, a movable isolation belt and a driving device. The driving device is used for driving the movable isolation belt to move on the tidal lane body, so that the vehicle flow direction of the tidal lane body is changed. The movable isolation belt is formed by connecting the electromagnetic isolation piers in sequence. The driving device is provided with a guide rail. Guide rail holes matched with the guide rail are formed in the electromagnetic isolation piers. Electromagnetic driving devices are arranged in the electromagnetic isolation piers. According to the automatic tidal lane provided with the electromagnetic isolation piers, through the electronic and mechanical self-movement of the movable isolation belt, the traveling direction of the tidal lane body can be adjusted through the isolation belt, vehicle flows in different directions are separated, and unnecessary labor is reduced. In addition, the tidal lane body is distinguished from other lanes through the isolation belt so that a driver can know the traveling direction of the tidal lane body more clearly, and the danger accidents such as going in the wrong direction are avoided; and the road traveling safety is improved, and the traffic burden is relieved at the same time.
