The invention discloses a subway passenger conducting management control system and a method thereof. The subway passenger diversion management control system comprises a passenger flow statistical unit, a density grading unit, an information transmitting unit, an information receiving unit and a central control unit, wherein the passenger flow statistical unit comprises an external door detector and an internal door detector; when a subway train departs, the central control unit starts the passenger flow statistical unit; and every time the subway train arrives at one station, the external door detector detects the number of passengers who walk into the door, the internal door detector detects the number of passengers who walk out of the door, the density grading unit grades the density of the current number of passengers in each carriage and sets the density factor, the information transmitting unit transmits the density factor of each carriage to the information receiving unit of the next station, and a subway working personnel reminds the passengers to go to the carriages with fewer passengers to wait for the train according to the density factor of each carriage received by the information receiving unit. Thus, the invention scientifically and effectively diverts the passengers, helps the subway stations to conveniently and quickly conduct the passengers, and facilitates traveling of people.
