Optimization of High-Speed Railway Line Planning Considering Extra-Long Distance Transportation

Table 2

Classification of HSR transportation distance.

Items	Range of distance/km	Major competitors	Features
Short distance	[100, 300)	Highway	There is fierce market competition with highway transportation
Middle distance	[300, 500)	Conventional railway	Obvious annexation effect on conventional railways
Medium and long distance	[500, 1000)	Airline	Airline passenger volume has been reduced to a certain extent
Long distance	[1000, 1500)	Airline	The shortest travel time is guaranteed
Extra-long distance	1500 or more	Airline	Strong competitiveness in Large-scale HSR network
