The invention provides a traffic indicator with an interlocking function and a traffic indicating system of the traffic indicator. The traffic indicator with the interlocking function comprises a communication module, a control module, a detection module and a display module, wherein the communication module, the detection module and the display module are connected with the control module respectively; the traffic indicator is communicated with an upper computer through the communication module; the traffic indicator is connected with an adjacent traffic indicator through the detection module of the traffic indicator; the traffic indicator is used for detecting the display state of the adjacent traffic indicator through the detection module, comparing the detected display state of the adjacent traffic indicator with a command issued by the upper computer and judging, and executing the command transmitted by the upper computer if the display content between the adjacent traffic indicators does not conflict; if the display content between the adjacent traffic indicators conflicts, the command of the upper computer is not executed, and relevant information is returned to the upper computer. By adopting the traffic indicator and the traffic indicating system of the traffic indicator, the contradiction of various traffic indication can be effectively prevented.
