Conflict-Avoidance-Oriented Airport Surface-Taxiing Guidance Light System Model

As the global air transportation industry has developed and the number of aircraft in hub airports has increased rapidly, airport surface traffic control by airfield lights and voice communication has caused increases in workload and human error for both controllers and pilots, especially in hub airports with high-density traffic flows and complex taxiway configurations. Therefore, the International Civil Aviation Organization (ICAO) has issued Doc. 9830 [1], which proposes guidelines for Advanced Surface Movement Guidance and Control Systems (A-SMGCS), including four basic functions: monitoring, controlling, routing, and guidance. Such systems aim to ensure that aircraft on the ground operate safely, rapidly, and in an orderly manner, even under conditions of high density, low visibility, and complex configurations [2,3]. ICAO Doc. 9830 [1] specifically points out that a high-level A-SMGCS should deploy guidance functions when the visibility is less than aerodrome visibility operational level [1].
