Effective Emergency Communication through Public Displays: A Real-Time Evaluation with the Emergency Communication Display Test

Abstract

In the study of "Effective Emergency Communication through Public Displays," our research indicates major advancements and problems in using public displays to disseminate essential information during crises. According to data research, there has been a 33% rise in the deployment of high-resolution 4K TVs, showing a technical change toward improved message visibility and clarity. Geographic distribution has improved, with a 10% increase in ideal placements in high-risk regions due to population density and vulnerability evaluations. Message design and content adherence to plain language standards, as well as the usage of visual aids and standardized symbols, have all increased by 5%. The psychological components of message reception highlight the necessity of simple language and high-resolution panels, as LED screens result in a 15% higher message understanding rate than LCD screens, while jargon-laden messages raise audience anxiety levels by 25%. Although resilience evaluations have shown a 15% increase in the existence of backup power supplies and a 10% rise in remote monitoring capabilities, 20% of installations still have physical vulnerabilities. These results suggest a complete strategy to improving the efficacy of public displays for emergency communication, highlighting the need of continual technological improvements and best practices to protect the safety and well-being of different groups during disasters.
