Static crowd density

WebFeb 28, 2024 · Unlike static crowd events where a crowd is formed in a specific location, or when a crowd is moving from a location to another (i.e., unidirectional), it requires more space (i.e., less density). If crowd mobility exhibits multiple non-unidirectional patterns, it would require even more space to be safe and is much harder to manage or control ...
