The invention discloses an intelligent isolating method for adjacent lanes and an intelligent moveable isolating pile system applied to it. The method orderly includes steps (1), a control client receives a signal, and judges if traffic jam happens according to the received signal; if it is, a step (2) is carried out; if not, the step (1) is repeated; (2), the control client sends the signal to amain intelligent module according to the received signal; (3), a main intelligent module outputs the signal to a slave intelligent module, and the slave intelligent module judges if the received signal is correct; if it is, the main intelligent module and the slave intelligent module output signals to control the work of every motor; if not, the main intelligent module outputs signal to control the work of the corresponding motor. According to the method and the system, the intelligentializing degree is high, and the automatic changing lane is automatically processed according to a real-time road vehicle information system; thus the intelligent traffic concept is satisfied; the method and the system can be continuously upgraded along with the technology development and combined with the existing traffic system to commonly develop.
