Operation Planning Method for Airport Support Vehicle Collision Avoidance Based on Dynamic Priority
[Purpose]To enable conflict avoidance operation planning for support vehicles in complex environ-ments,a dynamic priority classification method is proposed.[Method]This method prioritizes conflict avoid-ance based on levels of operation efficiency and risk.Additionally,a conflict avoidance operation planning mod-el were established,along with a two-stage algorithm for global path optimization.A low time complexity con-flict detection method was also proposed to ensure accuracy in solving large-scale complex problems quickly.[Result]Compared to the fixed-priority-based two-stage algorithm,the proposed approach improves conflict point reduction by 7.6%and reduces the vehicle-aircraft conflict ratio by 7.5%.[Conclusion]The proposed method meets the requirements of ensuring differentiated vehicle operation,and realizes the function of conflict avoidance path planning in a mixed operation environment of vehicles and aircraft.
