A queuing system is a system that helps with queuing passengers, passengers or guests to control the flow of people and streamline the queuing experience. As a business, you often do not know when there will be many people that need help. You can allocate staff resources based on former experiences but you will never really know if the resources fit the number of passengers. For example in the air transport industry controlling passenger flows are a big challenge. In airports, it can be a very difficult task to forecast busy time periods. By implementing a queuing system in an airport, the airport will easily detect busy time periods and make sure that no passenger is stuck in a queue for a long time. Right now more and more airports are implementing a virtual queuing system to manage passenger flows to make check-in and security areas more efficient.
