The invention discloses a purifying-type traffic cone based on automatic cruising and a working method thereof. The purifying-type traffic cone comprises a cone body, a purifying mechanism, moving mechanisms, a control mechanism and camera shooting mechanisms. The control mechanism comprises a processor, a driving device, a positioning device and a navigation device; the positioning device obtainsposition information of the cone body; and the navigation device generates the moving route of the cone body. The cone body comprises a camera shooting device for shooting a first image in front of the cone body, and further comprises a first through hole and a second through hole. The purifying mechanism is arranged in the cone body, and the first through hole and the second through hole are formed in the front face and the rear face of the cone body correspondingly. The purifying mechanism comprises an air blower, a first gas delivering guide pipe, an air purifying device and a second gas delivering guide pipe; the air blower is arranged in the first through hole; the first gas delivering guide pipe communicates with the air blower and the air purifying device; and the second gas delivering guide pipe communicates with the air purifying device and the second through hole. The moving mechanisms are used for driving the cone body to move, and the camera shooting mechanisms are arranged in all traffic road sections and used for shooting road condition information of the traffic road sections.
