Calculation of three behaviors.

Delay behaviors	Generation mechanism	Calculation	Range of application
Queuing delay	The facility service capability is less than passenger arrival rate		Ticket entrance, wicket, baggage check entrance, and so forth
Congesting delay	The facility cannot be used when the passengers arrive		Ticket entrances delay check caused by train late
Waiting delay	The facility capacity is insufficient, which leads to high density and low speed of passenger flow		The service capability of interface channel between service nodes is insufficient
