Emergency exit signs used in buildings aid occupant wayfinding during an emergency. However, research suggests that conventional signs lack the ability to attract people's attention in an emergency. This can result in the underuse of emergency exits and the overuse of main entrances with potentially fatal consequences. The effectiveness of signage depends on their ability to draw occupants' attention. A novel dynamic signage design, Active Dynamic Signage System (ADSS), was proposed to address this issue through incorporating flashing green LEDs into the arrow of conventional exit signs. Its effectiveness was tested in a series of experiments achieving a detection rate of up to 77% as opposed to 38% for conventional exit signs. In this paper, the signage model within the buildingEXODUS software was adapted to represent the ADSS and a series of simulations were run to investigate the potential effectiveness of the ADSS compared to conventional signs. The scenarios examined involved a supermarket geometry, 900 agents and three levels of signage configuration. The modelling results suggest that the ADSS can reduce total egress times for this structure by 18%, congestion by 36%, travel distances by 12%, resulting in a more efficient evacuation compared with that produced by conventional signage.

建筑物中使用的紧急出口标志可在紧急情况下帮助住户寻路。然而，研究表明，传统标志缺乏在紧急情况下吸引人们注意力的能力。这可能会导致紧急出口使用不足和主要入口使用过度，从而产生潜在的致命后果。标牌的有效性取决于它们吸引住户注意的能力。提出了一种新颖的动态标牌设计，即主动动态标牌系统 (ADSS)，通过将闪烁的绿色 LED 集成到传统出口标志的箭头中来解决这个问题。其有效性在一系列实验中得到测试，检测率高达 77%，而传统出口标志的检测率为 38%。在本文中，buildingEXODUS 软件中的标牌模型适用于表示 ADSS，并运行了一系列模拟来研究 ADSS 与传统标牌相比的潜在有效性。检查的场景涉及超市几何结构、900 个代理和三个级别的标牌配置。建模结果表明，与传统标牌相比，ADSS 可以将该结构的总出口时间减少 18%，拥堵减少 36%，旅行距离减少 12%，从而实现更有效的疏散。
