“…It has been reported that an evacuation sign with a green arrow is the best for catching one’s eye [ 21 ]. Similar results are also confirmed in [ 22 ] that green evacuation signs are better than red evacuation signs in group evacuations. An interesting result was found in [ 23 ], which showed that most evacuees follow green evacuation signs even though they think evacuation signs should be red.…”

In contemporary evacuation systems, the evacuation sign typically points fixedly towards the nearest emergency exit, providing guidance to evacuees. However, this static approach may not effectively respond to the dynamic nature of a rapidly evolving fire situation, in particular if the closest emergency exit is compromised by fire. This paper introduces an intelligent evacuation sign control mechanism that leverages smoke and temperature sensors to dynamically adjust the direction of evacuation signs, ensuring evacuees are guided to the quickest and safest emergency exit. The proposed mechanism is outlined through a rigorous mathematical formulation, and an ESP heuristic is devised to determine temperature-safe, smoke-safe, and congestion-aware evacuation paths for each sign. This algorithm then adjusts the direction light on the evacuation sign to align with the identified evacuation path. To validate the effectiveness of this approach, fire simulations using FDS software 6.7.1 were conducted in the Taipei 101 shopping mall. Temperature and smoke data from sensor nodes were utilized by the ESP algorithm, demonstrating superior performance compared to that of the existing FEL algorithm. Specifically, the ESP algorithm exhibited a notable increase in the probability of evacuation success, surpassing the FEL algorithm by up to 34% in methane fire scenarios and 14% in PVC fire scenarios. The significance of this improvement is more pronounced in densely congested evacuation scenarios.

“…People's risk perception can be affected by many factors, including individual characteristics and environmental factors. However, the built environment's impact is not limited to the layout of the building [14], and scholars have proposed several suggestions regarding the appropriate design of evacuation signs [15][16][17].…”

“…Un ejemplo concreto de aplicación tecnológica en la señalización de seguridad es el uso de tecnología luminosa en la señalización de equipos y salidas de emergencia. En situaciones donde la iluminación ambiental no permite una alta luminiscencia eficiente, como en el caso de los túneles, la tecnología luminosa proporciona una solución efectiva para garantizar la visibilidad y comprensión de las señales (Shi et al, 2022;Olander et al, 2017;.…”

ya que la mayoría de los usuarios solo miraron el pictograma del cartel, teniendo en cuenta la presión del tiempo.Como principales contribuciones, en primer lugar, hay que señalar que se ha desarrollado un entorno virtual inmersivo válido para mejorar el comportamiento del usuario en una situación de riesgo, así como para evaluar los impactos que elementos novedosos en la señalización pueden tener sobre ese comportamiento. Además, se ha desarrollado un protocolo guía para el diseño e implementación de señales de seguridad que permitan alcanzar un alto grado de eficacia en una situación de alta carga cognitiva y una serie de recomendaciones a seguir para el diseño de entornos virtuales gamificados con fines formativos en prevención de riesgos laborales.
