“…They concluded that smoke affected the route choice and that low‐placed exit signs had a positive influence on the closest fire exit selection. Jeon and Hong investigated the influence of phosphorescent guidance signs on human behavior under impaired visibility conditions. They emphasized that phosphorescent guidance signs facilitated an evacuation because of a decrease in the evacuation route.…”

Summary Emergency signage is important for safe escape when unexpected events (such as fires) occur. However, there are limited data on the difference in the effect of emergency signage on way finding processes between individual and group conditions. This paper aims to reveal how participants alone or in groups detect and accept the information conveyed by a signage system through an experiment in buildings. One hundred nineteen volunteers participated in the experiment, which included individual and group evacuation conditions. There were six decision points along the movement path where participants could select egress routes according to signage. Posttrial questionnaires and video recordings were used to derive the number of participants whose route choice was according to signage and to derive the decision time. Results demonstrate that both signage detection and acceptance probabilities under individual conditions are larger than those under group situations, because of social influence in groups. High‐placed signs have a positive effect on route choice, especially under individual conditions. Decision time for participants whose decisions are principally according to signs is not always smaller than that for participants whose decisions are not according to signs, eg, in group situations. These findings have implications for group evacuation modeling and signage design in buildings.

“…Currently, phosphorescent products are often used indoors, e.g., phosphorescent evacuation guidance and safety signs. 2) On the other hand, they are also being used outdoors, e.g., safety signs for evacuation area and studs on curbing between road and trail. The sunlight, by which phosphorescent products are irradiated outside, is gradually weaken at dusk, so the phosphorescent products for outdoor use must have long lasting luminescence that can be seen overnight and high weatherproof that can be kept properties over time.…”

“…In order to improve weather resistance and phosphorescent afterglow luminance property of the phosphorescent products, we investigated the effect of mixing ratio, firing temperature and matrix glass composition on afterglow luminance property of SrAl 2 2 (where x = 0.2, 3.7, and 6.2), which based on compositions of a glass frit for porcelain overgraze decoration. Mixed batches for the glasses were melted at 1500°C in air for 30 min and then quenched in water.…”

The effect of mixing ratio, firing temperature and matrix glass composition on afterglow luminance property of SrAl 2 O 4 : Eu 2+ ,Dy 3+ -glass composites were investigated. As a result, the brightness showed a maximum at 35 mass % of the mixing ratio of the phosphor for the glass and 780°C of the firing temperature. And it was increased with decreasing the Na 2 O content of the matrix glass. From the backscattered electron and the EDX analysis, it is thought that the intermediate layers generated between the phosphors and the Na 2 O-poor matrix glass work as antireflective and the phosphor particles in the composite emit phosphorescent light more efficiently. As higher the basicity parameter, B, the intermediate layer was clearer, which means that the reactivity at the phosphor/glass boundaries was lower, and the narrow reaction layers was formed.

“…The design elements (location, color, light, font, etc.) in the hub's guidance signs were compared (Jeon & Hong, 2009). Additionally, some researchers have evaluated guidance signs based on the analytic hierarchy process and satisfaction analysis method Choi, J.-S. & Yoo, H.-B., 2006).…”

Abstract:Internal guidance signs are critical for the normal operation of a comprehensive passenger transportation hub. In the present paper, the procedures, methods and restrictions on the development of guidance sign locations are summarized in terms of the planning and design method of guidance signs and an evaluation of guidance sign service manuals after a sorting and analysis of relevant literature. The results show that the existing location model fails to quantitatively describe the behavior characteristics of massive passenger flows and results in the spatial planning and design of guidance signage being inaccessible for many in mass passenger transit and spatial topological networks resulting from 3D hub architecture make the constraint conditions of location models more complex. Sophisticated guidance signs and location models responding to behavioral characteristics and spatial topological networks will be a trend of interest in the optimal layout of future comprehensive passenger transportation hubs.
