Airport surface operations involve multiple operational entities and complex operating environments. Given its relatively fixed structure， the airport surface has gradually become a bottleneck area for improving the efficiency of air traffic network operations. This paper proposes an airport surface operations model （ASOM） based on the Nagel-Schreckenberg （NS） cellular automaton. ASOM considers four aircraft operational characteristics and the cooperative operational mechanism between vehicles and aircraft. It accurately characterizes the aircraft taxiways and vehicle operation path structures while providing high-precision “aircraft-vehicle-surface” coordination simulation. Case studies are conducted using real airport structural data and surface monitoring data from Shenzhen Bao’an International Airport， and the average magnitude of error（AME） between the simulation results and the real operational data is less than 6%， demonstrating the accuracy and applicability of ASOM in depicting airport surface operations.
