Abstract

fetched live from OpenAlex

A crowd is a large number of people who gather at a specific location at the same time with or without shared agendas and/or emotions. A crowd is formed at sporting, holiday, religious, or political events. Proper management of a crowd is one of the major duties for the civic agencies such as police and fire departments to maintain public order and safety. When such management is ill-prepared and poorly executed, it can result in chaotic situations with human injuries and fatalities as well as damage to public properties. Good crowd management requires a good modelling of crowd dynamics and devising strategies accordingly. This paper presents the modelling and simulations of crowd dynamics that resembles the actual crowd behaviours using the social force model. With the realistic crowd dynamics, different scenarios and crowd management strategies were tested for optimal crowd flows. Our framework can be used to test various scenarios of an event that attracts a large crowd and devise suitable strategies for the crowd management.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
