The invention relates to the technical field of route network optimization design, and discloses an eVTOL-oriented urban air traffic route network planning method, which comprises the following steps of: for route network construction of eVTOL in urban air traffic, dividing an urban low-altitude airspace structure by analyzing multiple influence factors, and defining an operation height layer of eVTOL; then rasterizing and modeling the height layer of the low-altitude airspace, performing risk analysis on the urban low-altitude airspace by combining air and ground risk factors, constructing an urban low-altitude risk assessment model, calculating the risk cost of each grid unit according to the risk assessment model, delimiting the risk level, and further constructing a visual risk grid map; through a K-means clustering algorithm, obtaining a rising and landing point position of eVTOL-oriented urban air traffic route network planning; and finally, planning an eVTOL operation path network based on an A * algorithm improved by risk cost and penalty factors. According to the method, the flight area of the eVTOL can be divided in combination with the actual operation environment of the eVTOL, the flight route network is constructed according to the flight area, and safe and orderly flight of the eVTOL is guaranteed.
