Method, device and system of controlling passing vehicle according to traffic signal

The embodiment of the invention discloses a method, a device and a system of controlling passing vehicles according to traffic signals. The method includes the following steps: receiving electromagnetic wave signals according to traffic signals, the electromagnetic wave signals being generated according to traffic signals; analyzing the electromagnetic wave signals to be corresponding passing vehicle prompting instructions; and prompting running states of vehicles according to the passing vehicle prompting instructions. Through application of the embodiment, the corresponding electromagnetic wave signals are generated according to the traffic signals, are sent out and are analyzed to be the corresponding passing vehicle prompting instructions for prompting the running states of the vehicles, and the running states of the vehicles are prompted through the electromagnetic wave signals, thereby reminding users to carry out corresponding operations, avoiding traffic violation and traffic accidents and meeting dem
