In order to improve the safety management level of airport surface operation,the problem of identifying hot"node-segment"in surface taxiway network of complex airport was investigated with overall consideration of road network structure and trajectory data.Firstly,the characteristic elements of surface physical structure were extracted and integrated,and the original model and dual model of surface taxiway network were constructed.Secondly,a characteristic index system and its specific measurement method of surface taxiway network were established aiming at two perspectives of static structure and dy-namic traffic flow,and the index screening mechanism based on the accumulative information contribution rate was designed.Finally,the CRITIC-VIKOR method was used to classify and identify the hot"node-segment"in the surface taxiway net-work,and the example verification was carried out.The results show that the identification results of hot"node-segment"based on 5%evaluation benchmark are consistent with the actual operation of the airport,mainly located in the primary taxi-ways S/W,parallel taxiways C/E,the entrance of runway 15/33,and partial regions of APN02.The research results can pro-vide decision-making reference and methodological guidance for the safe and effective management of airport surface opera-tion.
