The invention relates to an intelligentized traffic isolation system. The structure of the system comprises a remote control center and a self-driven movable isolation fence with a central processor and a wireless communication module, the structure of the self-driven movable isolation fence also comprises a group of movable bases with wheels and wheel-driving mechanisms and a group of movable stakes, and the movable stakes are connected by means of connecting rods and arranged on the bases. The intelligentized traffic isolation system is characterized in that: the structure of the system also comprises an accurate positioning mechanism, the accurate positioning mechanism comprises a group of spikes with magnets as references, the spikes are arranged on a road traffic marking, a pair of Hall elements are symmetrically arranged on the left and the right ends in each base, and based on the structure, the intelligentized traffic isolation system can be accurately positioned after a roadway is adjusted according to need. An intelligent median strip for easy-to-jam intersections is provided, the isolation fence can be automatically adjusted and moved, and not only is the tidal functional adjustment of urban roads realized to solve the problem of urban road jams in rush hours, but also the heavy work of the road administration department can be reduced.
