1. A system for preventing a secondary accident, comprising:

  • a terminal configured to;

    have a global positioning system (GPS) navigation capability;

    monitor and display a driving state and an accident state of a vehicle;

    transmit information on the driving state and the accident state via a communication network; and

    display information received on a screen; and

    a server platform configured to;

    exchange information with the terminal;

    include an algorithm for determining an occurrence of an accident based on the information of the driving state and the accident state received from the terminal; and

    inform other terminals of the occurrence of the accident;

    wherein the information on the driving state comprises a speed of the vehicle, a location of the vehicle, and acceleration in three different directions of the vehicle; and

    wherein the algorithm includes instructions for;

    filtering each acceleration measured on X (rostrocaudal direction), Y (lateral direction), and Z (longitudinal direction) axes;

    summing the filtered accelerations;

    detecting an occurrence of an impact based on the summed acceleration; and

    determining whether the occurrence of the impact is caused by the occurrence of the accident.
