common.Furthermore, the integration of these displays with emergency alarm systems was a prevalent feature, as seen in more than 70% of the public display installations assessed.This integration exemplifies a favorable trend toward enabling seamless communication during emergencies, with high-resolution displays increasing the visibility of emergency messages for a wide range of audiences.GIS analysis was used to examine the geographic distribution and placement of public displays, which revealed that around 82% of displays were deliberately placed in high-traffic regions, transit hubs, and commercial locations.The choice to base these placements on population density and vulnerability assessments is consistent with best practices, ensuring that public displays are ideally positioned to benefit individuals who are most likely to be impacted by catastrophic situations.The message design and content study revealed a favorable trend, with 90% of emergency alerts following plain language standards and 85% including visual aids and standardized symbols.This commitment to best standards in message design improves message clarity and understanding, which is crucial for providing information to various audiences quickly and comprehensibly during crises.During the investigation, psychological testing demonstrated that messages placed on LED panels were interpreted 15% more precisely than those displayed on LCD screens.Furthermore, audience reactions to communications under simulated emergency events revealed that messages including jargon increased anxiety levels by 20%.These results illustrate the relevance of display technology and message design in influencing audience reactions, emphasizing the efficacy of LED panels and the need of avoiding jargon in emergency warnings.According to resilience studies, 95% of public display systems had backup power sources and 80% had remote monitoring capabilities.Physical weaknesses, such as sensitivity to harsh weather, were discovered in 25% , 01105 (2024) BIO Web of Conferences https://doi.org/10.1051/bioconf/2024860110586 RTBS-2023 of installations.While the presence of backup power sources and remote monitoring suggested a proactive approach to system resilience, the presence of physical vulnerabilities highlights the need for improvements in the physical durability of public displays, especially in areas prone to extreme weather events.An examination of the technological landscape and integration found a significant movement toward high-resolution screens.According to the research, 4K resolution screens are now present in 80% of public display installations, a huge rise over the previous year when they accounted for just 60% of the displays.This reflects a 33% increase in the use of high-resolution displays.Integration with emergency alert systems has also increased, with 75% of displays now linked, a 7% increase over the previous year.According to the geographic distribution and placement research, public displays are still carefully placed in high-traffic regions.Notably, 85% of displays were found in these regions, a 5% increase over the prior evaluation.These placements were influenced by population density and vulnerability evaluations, which resulted in a 10% increase in ideal placements in high-risk locations.This rise reflects an increasing focus on taking these considerations into account when deciding display location.The examination of message design and content revealed a favorable trend in best practices adherence.Specifically, 95% of emergency communications now employ plain language principles, a 5% improvement over the prior review.The usage of visual aids and standardized symbols has also increased, with 90% of communications now using these features, a 5% increase.These advancements in message design and content alignment with best practices reflect a continuing commitment to improve communication clarity and understanding.Audience reactions varied significantly depending on display technology and message content, according to the psychological research.Messages exhibited on LED panels were grasped with 85% accuracy, a 15% improvement over messages displayed on LCD screens.Furthermore, communications containing jargon caused a 25% rise in anxiety among the audience.These results underscore the need of employing clear language and high-resolution displays to enable successful communication during crises, as well as the major influence of display technology and message design on audience reactions.Challenges and Resilience: According to the resilience evaluations, public display systems have made significant progress in addressing possible weaknesses.In particular, 90% of systems now have backup power sources, a 15% increase from the prior evaluation.Furthermore, 80% of installations now have remote monitoring capabilities, a 10% increase.Physical weaknesses, such as vulnerability to harsh weather conditions, were discovered in 20% of installations, showing that there is still opportunity for development.These findings show the progress achieved in improving system resilience, but they also highlight the continuous need to address physical weaknesses in order to build a stronger emergency communication infrastructure.
