Abstract：The continuous growth of air traffic has caused route congestion and airspace capacity constraints.To minimizethe workloadof air traficcontrollersand enhance the eficiencyof airspaceutilization，aconflict-free trajectory planning approach specificallydesignedforthe backgroundof fre route airspace is proposed.A multiobjective mixed integer linear programming（MILP）model is established，with the core objective of generating flightaltitude profiles thatmeet the departure boundary altitudeagreementsand identifying the nearestand optimal intermediatewaypoints for conflicting aircraft.The airspace is discretized into diamonds to set the heading adjustment range and improve the computational speed of the model，whilea hierarchical sequence method is employed to solve the multi-objective problem.Scenarios with continuous traffc flow are generated using real airspace structures and traffcflow higher than thecurrent operational situation.Experimental results show that 94.625% of the samples can achieve conflict-free trajectories within 12O seconds.The proposed conflict-free trajectory planning approach has significant implications for future development of free-route airspace.
