  As an indispensable spatial direction information indicator for emergency
evacuation, the spatial relationship between safety evacuation signs and
evacuees will affect the response time of evacuees and the evacuation
efficiency. This paper takes 2 kinds of common safety evacuation signs,
hangtag-type and embedded, as the research object and designs space direction
information transmission efficiency and capability simulation experiment and
fire drill, the efficiency and capability of spatial direction information
transmission of safety evacuation signs are studied. The results show that the
space angle of the hangtag-type safety evacuation sign is inversely
proportional to the information transmission efficiency and capability of the
space direction, and the fire drill also confirms this conclusion. When the
spatial angle of the embedded safety evacuation sign is 5{\deg}, the spatial
direction information transmission efficiency and capability increase.
Simultaneously, the average escape time of the participants in the fire drill
was lower, and the percentage of choosing unfamiliarity exports increased. The
evolution of spatial angle has no significant effect on the intention of the
response of subjects of different genders; when choosing the direction, males
are more easily affected by the change of spatial angle than females; the
confidence level of females' choice is more easily affected by spatial angle.
In addition, according to the research results, the corresponding
three-dimensional structure safety evacuation signs are designed. The
functional structure of the safety evacuation signs is perfected, which can
effectively improve the efficiency of fire emergency evacuation.
