The invention discloses a traffic flow distribution method for an urban logistics unmanned aerial vehicle. The method comprises the following specific steps: calculating the safety impedance of each flight segment of an air route network according to the safety influence on ground personnel when the logistics unmanned aerial vehicle flies; considering the maximum traffic capacity and flight energy consumption of the air route, and calculating the efficiency impedance of each leg of the air route network; calculating the comprehensive impedance of the leg of the urban low-altitude public route network according to the safety impedance and the efficiency impedance; establishing an urban low-altitude airway network traffic flow dynamic distribution model, and determining constraint conditions of traffic flow distribution; and finally, completing public route network traffic flow distribution by using a stage distribution method. According to the traffic flow distribution method for the urban logistics unmanned aerial vehicle, efficient and safe flight of a low-altitude aircraft can be ensured, and the traffic flow operation efficiency of a low-altitude airspace is improved.
