Abstract:Concerningtheprominentproblemsofrunwayincursionsandaircrafttaxiconflicts

thedesignworkofconflictdetectionandalarmingsystemforairportsurfacewasanalyzedbasedonthefiveprospects of taxiwayconflictalarming

passingpathabilitydetectionanddeviationplanningalarming.Basedontheanalysisoftheoperationrulesofaircraftonthegroundandexclusiveprincipleofaccessingtocriticalresources

thresholdtraitsmodelforconflictdetectionalarmwasestablished.Definedrulesaboutfourkindsofairportcomponentsweregiven.Andwiththedefinitionofprofessionaldatastructureandtype

planconflictdetectionwasimplemented.Topreventfalsealarmandmissingalarm

threeconflictalertregionsweredesignatedforeachaircraft.Theconflictintheshorttermwaspredictedbasedonpolygonoverlapdetection.Simulationresultsshowedthatplanroutinginformationcanmatchwithroadnetworkmodelquickly.Throughtraversingcomponents

thetype

timeandlocationoftheconflictcanbetested

andalarmcanbedisplayedinthecorrespondingwindow.Thesimulationresultscoincidedwithconclusionsoftheoreticalanalysis.
