The present invention relates to a traffic accident occurrence notification system using LED display lamps, comprising: an emergency message generating unit provided in a mobile means so as to generate a wireless signal in an emergency situation; a plurality of LED display lamps provided together with street lamps provided on a road so as to receive the wireless signal from the emergency message generating unit and display a turned-on or flickering state from a position at which the wireless signal is received to a position at which a distance is set at a rear; and a street lamp control server for controlling the street lamps and the LED display lamps and determining the position at which the wireless signal is received so as to transmit information thereof to a rescue server. The present invention provides the emergency message generating unit in a vehicle so as to detect an accident or enable a driver to recognize an emergency situation and select propagation of the emergency situation, and enables a nearby street lamp to receive the wireless signal when the emergency message generating unit transmits the wireless signal so as to turn on or flicker the LED display lamps such that the LED display lamps located at the rear of a distance set at a corresponding position are turned on or flicker so as to make a driver in a rearward vehicle recognize the occurrence of the emergency situation ahead, thereby preventing the occurrence of a secondary collision accident.
