FIRE EXIT SIGNAGE EXPERIMENT 2009
Page currently being updated..please bear with us.
Individual participants were asked to navigate their way around the selected building interior until they reach a defined exit. Participants were free to select their own route through the building and proceeded until the end point was reached or a member of staff indicated the trial had ended.
Participants were equipped with head gear fitted with a video recording device that effectively recorded what they saw. The actions and behaviour of the participants were also recorded by video cameras located at fixed points throughout the building.
At the end of the trials, participants were requested to complete a questionnaire and participate in a one-to-one interview. Paper provided courtesy of the Fire Safety Engineering Group - University of Greenwich
Summary of trial:
While on average only 38% of people unfamiliar with a building layout are likely to detect regulatory standard signs, on average 97% of people are likely to follow the guidance provided by signs once they are detected. These results also suggest that current emergency guidance signs are less effective as an aid to wayfinding than they potentially can be.
If they can be made to be more obvious while maintaining the simplicity and strength of the guidance information they provide, they are likely to become very effective due to high acceptance of signage information.
To address this problem it is necessary to increase the affordance of the sign. This can be done in a number of ways such as increasing the size of the sign, making the sign standout more from the background, or introducing addition sensory stimuli such as flashing lights and auditory signals. However, it is essential that the simplicity and strength of the information conveyed by the sign is not decreased through enhancing the affordance of the sign.

DYNAMIC SIGNAGE SYSTEM (DSS)
FIRE EXIT SIGNAGE EXPERIMENT 2012
Summary of trial:
The results obtained from the this trial showed that the Dynamic Signage System (DSS) achieved at detection rate of 77% when participants directly approached the sign (i,e. approach angle perpendicular to the surface of the sign) and 72% when approached at an angle (i.e. approach path tangent to the surface of the sign) . Under the same experimental conditions as decribed in trial one above (passive), static signs produced detection rates of 38% and 37% respectively.
This is an important result as it suggest that the dynamic sign can achieve a significantly high detection rate from a variety of angles.
The difference in the detection rates achieved by the DSS compared with the conventional static (passive) signage system is statistically significant.
The high signage detection and compliance rates were also supported by the result of the post-trial interviews. A significant majority of the participants ( 80 to 90% ) confirmed that the flashing lights assisted them in making a quick route decision and reinforced this decision, while the flashing light did not cause confusion and hesitation to them.
Passive trials 2009 conducted by the Fire Safety Engineering Group (FSEG), headed by Professor Ed Galea, at the University of Greenwich.
Dynamic Trial 2012 conducted by the FSEG as part of the the EU funded Getaway project.
Dynamic Trial 2013 held at the St Cugat Railway Station in Barcelona.

PASSIVE & DYNAMIC VIDEO SAMPLES
FIRE EXIT SIGNAGE EXPERIMENT
The specific purpose of this experiment as detailed above, was to determine the likelihood that building occupants involved in an evacuation situation and faced with a route decision point and who are located within the Visability Catchment Area (VCA) of an emergency sign will perceive the sign, correctly interpret its information and correctly act upon the information.
68 test subjects took part in the trial. Video footage recorded by head mounted camera was used to not only measure the decision time
but also to identify different behaviours during the decision period. Unfamiliar participants who fail to detect the sign require on average 5.6 seconds to decide which direction to take at the decision point.
The emergency escape route sign shows that evacuees should go left at the junction.
62% of the test subjects did not see the sign.
The specific purpose of this experiment was to replicate the experiment above but with the Evaclite Dynamic Signs to determine the likelihood that naïve building occupants involved in an evacuation and faced with route alternatives who are located within the VCA of a dynamic emergency sign (i.e.have the opportunity of perceiving the sign), correctly interpret its information and correctly act upon the information. We then evaluate the level of improvement in detectability of the new dynamic sign compared with the conventional static sign. 58 test subjects took part in the trial.
Unfamiliar participants who detected the sign required on average 1.8 seconds to decide which direction to take at the decision point.
The dynamic emergency escape route sign shows that evacuees should go left at the junction.
77% of the test subjects did see the sign.
The decision time was three times faster.
