Waiting outside in a long line in front of a music building is not always pleasant. Sometimes concert visitors stand in line for hours and even in the rain. This waiting time and experience are related to the overall experience of the concert night. Therefore, the waiting time should be reduced and the waiting should become more pleasant. To achieve this, research has been done into the entrances of music buildings and the public outdoor space, that function as waiting and reception area, around music buildings.

In addition, attention is given to crowd control and fire safety. At large events, order and security around crowds are extremely important. Therefore, it is essential to have a clear understanding of how people can leave the building in a structured way, especially in case of an emergency. With crowd control, it can be ensured that the number of people never becomes too large. And fire safety requirements, such as certain dimensions that doors, corridors, and staircases must meet, ensure that the flow is optimal and that no congestion occurs.
