People often prioritize familiar exits over the closest emergency exits during evacuations due to a lack of real-time information, highlighting the need for systems that guide behaviour. This user-centred design research insight is drawn from a 2014 study published in ERA. Using Observational study and simulation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design evacuation systems that actively communicate critical information to guide users towards the safest and most efficient exits, rather than relying solely on static signage.

Key Findings
- 01Occupants often ignore designated emergency exits in favour of familiar primary exits.
- 02Pre-movement behaviour and information availability are more critical to survival than actual movement speed.
- 03A lack of clear, relevant information leads to unpredictable and potentially dangerous occupant behaviour during evacuations.
Application
Design takeaway
Design evacuation systems that actively communicate critical information to guide users towards the safest and most efficient exits, rather than relying solely on static signage.
How to apply
Implement dynamic signage systems that can change based on real-time sensor data (e.g., fire location, smoke levels) to direct people to the safest exits.
Project actions
- 01Consider how to visually communicate urgency and direction effectively.
- 02Research existing emergency evacuation systems and their limitations.
- 03Explore the use of technology to provide real-time updates.

Variables
Strengths & Limitations
Strengths
- +Highlights the critical role of information in emergency response.
- +Emphasizes the importance of pre-movement behaviour.
Limitations
It's hard to perfectly replicate the fear and chaos of a real emergency in a controlled experiment.
Reliability & validity
The reliability of findings would depend on the consistency of participant behaviour across similar scenarios. Validity would be enhanced by comparing findings with real-world incident data and using diverse participant groups.
Think critically
To what extent can technology truly overcome deeply ingrained human behaviours and habits in a panic situation?
Design Principles
"In critical situations, provide clear, actionable, and context-aware information to override ingrained user habits and ensure optimal decision-making."
This insight is critical for designing safe public spaces and emergency systems. Understanding user behaviour, particularly their reliance on familiar cues, allows for the development of more effective evacuation strategies and technologies that can override ingrained habits in critical situations.
What This Means for Your Design
People don't always go to the nearest emergency exit because they don't know what's happening. They stick to what they know, like the main door. So, we need systems that tell them where to go during a fire.
How to use in your project
- 1.Use this research to justify the need for an information-driven component in your design project.
- 2.Refer to this study when discussing user behaviour and decision-making under stress.

Paragraph starter
Research indicates that during emergency evacuations, occupants frequently bypass designated emergency exits in favour of familiar primary exits due to a lack of real-time information regarding current conditions and optimal egress routes. This pre-movement behaviour, influenced by psychological factors such as familiarity, is a significant determinant of survival. Therefore, the development of information-driven systems is crucial for guiding occupants towards the most effective escape paths.
