Vegetation that obstructs views and offers concealment negatively impacts perceived safety and user preference in city parks, primarily because it induces a sense of danger. This user-centred design research insight is drawn from a 2019 study published in Sustainability. Using Quantitative analysis of photographic stimuli. with 112 photographs (contextual data, not participant count), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize visual accessibility in park design, especially in areas intended for public gathering or circulation, to enhance perceived safety and user preference.

Key Findings

  • 01Vegetation that obstructs views and provides concealment reduces perceived safety.
  • 02Vegetation that obstructs views and provides concealment negatively impacts user preference.
  • 03The negative impact of dense vegetation on preference is largely mediated by the reduced sense of safety it creates.
  • 04When the effect of perceived safety is accounted for, vegetation density has a less significant direct impact on preference.

Application

Design takeaway

Prioritize visual accessibility in park design, especially in areas intended for public gathering or circulation, to enhance perceived safety and user preference.

How to apply

When designing or redesigning urban parks, use vegetation strategically to define spaces without creating blind spots. Consider incorporating open, well-lit areas alongside more secluded, vegetated zones, ensuring that the latter do not compromise overall safety perception.

Project actions

  • 01When evaluating existing park designs, consider how vegetation placement affects visibility and user comfort.
  • 02When proposing new park designs, use mood boards or 3D models to illustrate how different planting strategies impact perceived safety.

Method & Evidence

AimTo investigate how vegetation characteristics, specifically visual accessibility and concealment effectiveness, influence user preference and perceived safety in city parks, and to understand the mediating role of perceived safety.
MethodQuantitative analysis of photographic stimuli.
ProcedureParticipants evaluated 112 photographs of city park scenes, assessing vegetation's visual accessibility and concealment effectiveness. Correlation, regression, and mediation analyses were used to determine the relationships between these factors, perceived safety, and user preference.
Sample112 photographs (contextual data, not participant count)
ContextUrban park design and landscape architecture.

Strengths & Limitations

Strengths

  • +Employs statistical analysis to quantify relationships between variables.
  • +Utilizes mediation analysis to explore the underlying mechanisms of user perception.

Limitations

Photographs are static and two-dimensional, unlike real-world park experiences. The study didn't account for different types of vegetation or their specific aesthetic qualities, only their impact on visibility and concealment.

Reliability & validity

The study's reliability is supported by the use of statistical analyses. Validity is enhanced by examining mediation, which probes the causal pathways of perception, though reliance on photographs may limit ecological validity.

Think critically

To what extent does the 'sense of danger' from dense vegetation influence preference, and could other factors, like perceived privacy or natural beauty, counteract this negative effect in certain contexts?

05

Design Principles

"Design for clear sightlines to foster a sense of security and positive user experience in public spaces."

Understanding how landscape elements influence user perception is crucial for designing public spaces that are both aesthetically pleasing and feel safe. This insight helps designers balance natural elements with the need for open sightlines to foster positive user experiences.

06

What This Means for Your Design

If you want people to like a park and feel safe in it, don't plant trees and bushes too close together where you can't see what's going on. People feel scared when they can't see around them, and that makes them like the park less.

How to use in your project

  • 1.Reference this study when discussing the importance of visual accessibility in your design proposal for public spaces.
  • 2.Use the findings to justify design decisions related to landscaping and sightlines in your design project.

Quick Cite

Paragraph starter

Research indicates that vegetation density significantly impacts user perception in public spaces. Specifically, dense planting that obstructs views and offers concealment reduces perceived safety and overall user preference, primarily due to an induced sense of danger. Therefore, design interventions should prioritize maintaining clear sightlines to foster a more secure and enjoyable user experience in urban parks.
