How to solve the problem of speed of ticket sales during peak hours?

Peak scheduling differs greatly from the usual passenger flow. If more gates are purchased, it will be wasted. If the purchase is less, peak scheduling is not enough. Therefore, the following methods are used to solve the speed of peak scheduling ticket sales.
1.Adopt wireless handheld ticket checking machine for ticket checking.
2.Put the brake lever down or put the swing arm and wing arm in the normally open position, you only need to check the ticket.
3.Print out the ticket from the ticket machine in advance, that is, sell the pre-sale ticket. During peak hours, manual ticketing seats can be added to increase the speed of ticket sales. Unsold tickets can be "refunded".
