Web6 de dez. de 2024 · Abstract: It is significant to discovery the impact of panic on crowd movement and study the panic propagation mechanism which can help real crowd control. This paper focuses on panic propagation dynamics in a high-density crowd based on information entropy theory and Aw-Rascle model. A novel concept of panic entropy is … WebInformation is associated with the entropy of data sets. Data sets with low entropy can be compressed and contain less information than data sets with maximal entropy, which cannot be compressed and contain exactly themselves as information. There are various ways to explain these relations mathematically.
