Optimized ST-Moran’s I Model for Characterizing the Dynamic Evolution of Terminal Airspace Congestion

Table 3

The range of values for Local ST-Moran Index and the corresponding meanings.

Variable name	Value range	Interval	Meaning of state
	(−∞, +∞)	(0, +∞)	At a certain moment, the operating state of the segment has abnormal fluctuations and tends to be consistent with the operating state of its adjacent segment. The larger the value, the more obvious the consistency
		0	At a certain moment, the operating state of the flight segment fluctuates within the normal range and does not correlate with the state of its adjacent flight segment
		(−∞, 0)	At a certain time, the operating state of the segment has abnormal fluctuations and is opposite to the running state of its adjacent segment. The larger the value, the more obvious the reverse difference
