The invention discloses a path planning method based on aircraft conflict risk and taxiing cost. The method comprises a scene link diagram construction module, a conflict risk quantification module and a path planning module. The conflict risk quantification module predicts the taxiing distance of the aircrafts by using a Gaussian distribution probability model based on the taxiing speed of the aircrafts and the time of completing the milestone event, and further calculates the conflict probability between the aircrafts; the path planning module considers a conflict probability value and taxiing cost between aircrafts, searches an optimal taxiing path of the aircrafts within a safety threshold range through an improved ant colony algorithm, optimizes the taxiing path of the aircrafts in a pre-planning stage, and has the advantages of improving the airport scene operation efficiency and reserving sufficient scheduling time. The aircraft can slide on the premise of being as safe as possible, and cost consumption is reduced.
