Guides boost evacuation speed: placing them far from exits cuts time. Dynamic guides work best in low visibility with higher distance‑ratio; static guides hit optimal performance at 40‑60% of platform length. #EmergencyPlanning#CrowdSafety
Cognition shapes evacuation in heritage districts: high‑cognitive people pick clear, fast routes; medium‑cognitive rely on visual cues, making local, redundant choices; low‑cognitive follow simple paths or others. Guides can be tiered for resilience.

Using MARL with PPO, a navigation agent learns escape routes while a design agent shifts doors based on movement. Implicit coordination cuts evacuation time, showing dynamic floor‑plan adaptation can boost emergency egress.

Experiments show that well‑placed obstacles near exits boost evacuation efficiency by up to 29.6%, cut lateral rushes 49.9%, raise crowd alignment 26% and lower wall pressure—key for high‑density crowd safety.

1. Identify the core findings
- Groups (especially 2‑person sub‑groups) tend to split during fire evacuations.
- Exit choices are influenced by the usual individual factors (distance, familiarity, smoke).
- Social influence (what other group members d...

An integrated water‑transport optimization model boosts flood evacuations in smart cities: it syncs reservoir releases with dynamic traffic routing, extending warning time, cutting congestion, and lowering exposed people—offering a scalable decision‑support tool.
Dynamic Dijkstra‑A routing using GPS data cuts congestion and boosts safety in wildfire evacuations. Region‑based, staggered departures with realistic response times beat simultaneous exits. #wildfire
