  • Patent number: 11217054
    Abstract: Managing passenger flows is an important issue in modern buildings. Particularly in high buildings there will be a lot of people arriving and leaving typically through one access floor. When passenger flows are not managed and passengers are not instructed facilities of buildings are not in optimal use. People may be queuing for one elevator group when another elevator group is not used in full capacity. This can be improved by using an access gate arrangement where the controller of the access gate arrangement receives information from external systems in the building.
