Sensing Streetscapes: How Amsterdam Is Using Neuroscience to Build Cities That Feel Human
A groundbreaking research initiative bridges urban design with cutting-edge neuroscience to create human-scaled environments in the age of densification.
The Urban Challenge: Building for People in the Age of Densification
Imagine standing on a street where the buildings tower so high they block the sunlight, where the sheer scale of your surroundings makes you feel insignificant and anonymous. Now imagine a different street—one with active ground floors, colorful balconies, trees, and benches where people naturally gather. What makes one space feel oppressive and the other inviting? This question lies at the heart of a groundbreaking two-year research initiative in Amsterdam that bridges urban design with cutting-edge neuroscience 3 5 .
New homes needed in Amsterdam over the next 5-10 years 3
Increase to Amsterdam's current housing stock 3
Amsterdam, like many thriving cities worldwide, faces an enormous challenge: the need to accommodate 50,000 to 90,000 new homes within its existing urban fabric over the next five to ten years 3 . This represents approximately 10% of the city's current housing stock. The inevitable solution is densification—building upward rather than outward. Yet this approach comes with significant risks to urban liveability. As the researchers behind the "Sensing Streetscapes" project note, these new high-rise typologies represent "un-Dutch" building forms that could fundamentally alter the character of the city and the well-being of its residents 3 .
The critical question driving the research is whether classical urban design solutions—developed for traditional low-density environments—can create streetscapes with a human scale when applied to these new high-density settings 3 .
To answer this, a multidisciplinary consortium turned to an innovative combination of technologies from neuroscience and architecture, exploring the subtle relationship between the designed environment and how we visually perceive it 5 . Their findings could reshape how cities worldwide approach urban densification, ensuring that we build not just more housing, but better neighborhoods that promote human well-being.
What Exactly is Human-Scaled Densification?
The Concept of Human-Scale City Design
Human-scale city design prioritizes the comfort, well-being, and natural proportions of people within urban spaces 4 . It represents a fundamental shift in urban planning—from cities designed primarily for cars and efficiency to those crafted for pedestrians, cyclists, and the richness of human experience. Think of the difference between a massive highway interchange and a pedestrian-friendly shopping street lined with cafes. One isolates and divides, the other connects and invites 4 .
Key aspects of human-scale design include:
- Walkable distances where daily amenities are within easy reach
- Varied building heights that feel approachable rather than imposing
- Active public spaces that serve as hubs for community interaction
- Green infrastructure that integrates nature into the urban fabric
- Mixed-use development that combines residential, commercial, and cultural spaces 4
From a psychological perspective, our built environment profoundly influences our emotions and behavior. Studies in environmental psychology have demonstrated how towering skyscrapers can contribute to feelings of anonymity and alienation, while environments designed with human proportions foster a sense of belonging and security 4 . This connection between urban form and mental well-being is crucial yet often overlooked in traditional urban planning.
The Emerging Field of Neuro-Architecture
The "Sensing Streetscapes" project operates at the intersection of urban design and neuroscience, representing the emerging field of neuro-architecture 5 . This discipline uses objective measurements of human physiological responses to understand how built environments affect us at a fundamental level.
Rather than relying solely on traditional observations or questionnaires, neuro-architecture employs technologies like eye-tracking to see precisely what elements in our environment capture attention, evoke curiosity, or create discomfort 5 . This approach allows researchers to move beyond assumptions about what "should" work in urban design and instead understand what actually resonates with people at a perceptual level.
Neuro-architecture bridges the gap between architectural design and neuroscience, using technologies like eye-tracking, EEG, and biometric sensors to understand how people respond to built environments at a physiological level.

Inside the Sensing Streetscapes Experiment: Eye-Tracking Amsterdam's Streets
Research Methodology and Approach
The "Sensing Streetscapes" research employed an innovative methodology combining eye-tracking technology with traditional urban analysis to understand how people visually engage with different street environments 5 9 . The research was conducted as a two-year explorative study focused on developing design principles for liveable streetscapes in high-density settings 5 .
The project represented a collaboration between the Chairs of Urban Analytics and Civic Interaction Design, bringing together urban designers, city planners, and scientists 5 . This multidisciplinary approach allowed the team to interpret the eye-tracking findings through both technical and design lenses.
Amsterdam's streetscapes combine historical and contemporary architecture, providing diverse environments for study.
Experimental Procedure
Selection of Diverse Streetscapes
Researchers identified various street environments in Amsterdam representing different architectural styles, densities, and spatial configurations.
Eye-Tracking Data Collection
Participants were equipped with mobile eye-tracking devices that recorded their visual attention as they navigated these streets. This technology precisely measured where and how long people looked at different elements in their environment 5 .
Pattern Analysis
The research team analyzed the eye-tracking data to identify common patterns in what elements naturally drew attention and what was overlooked 9 .
Design Principle Development
Based on these patterns, the team began developing evidence-based design strategies for creating human-scaled environments even in high-density contexts.
Surprising Findings: Where Do Our Eyes Naturally Rest?
The preliminary findings from the study revealed fascinating patterns in human visual behavior in urban environments—some of which challenged conventional wisdom in urban design.
Social Elements
Participants' eyes were naturally drawn to people, traffic, and signs 9 .
Transitional Spaces
"Zones where interior and exterior comes together in the active plinth of buildings and terraces in front, draws instantly the attention" 9 .
Architectural Details
When a building blocks the view at the end of a street, the eye is naturally drawn toward architectural elements that break up the facade 9 .
| Visual Attention Category | Specific Elements That Drew Attention | Interpretation and Design Implications |
|---|---|---|
| Social Elements | People, terraces, active building plinths | Humans are inherently social; spaces that facilitate people-watching enhance engagement |
| Architectural Details | Oriental windows, colorful balconies, building ornamentation | Fine-grained details provide visual interest and wayfinding cues |
| Navigational Elements | Signs, distinctive landmarks, street names | Clear legibility supports spatial orientation and comfort |
| Natural Elements | Not specifically mentioned in results | Further research needed on vegetation and natural features |
Designing Streets That Feel Human: Principles from the Research
Translating Findings into Design Strategies
Based on their eye-tracking results and urban analysis, the Sensing Streetscapes team began developing practical design principles for creating human-scaled environments in densifying cities. These strategies aim to balance the necessary efficiency of high-density development with the psychological needs of urban residents.
The research suggests that successful streetscapes in high-density settings incorporate:
Active Building Plinths
The ground floors of buildings should engage pedestrians with transparent facades, active uses, and visible human activity. The study found these zones instantly draw attention and create visual interest 9 .
Architectural Articulation
Building facades should incorporate varied elements like oriel windows, balconies, and color variations that break up large masses and provide visual wayfinding cues 9 .
Social Scaling
Even in high-density environments, design should facilitate natural social encounters and people-watching opportunities, since the research consistently showed that people are naturally drawn to observe other people 9 .
Visual Terminations
When streets are terminated by buildings, those structures should feature engaging facades with elements that guide the eye naturally upward rather than creating stark visual barriers 9 .
Active building plinths with transparent facades create engaging streetscapes that draw visual attention.
The Broader Context: Street Design and Mental Well-Being
The Sensing Streetscapes research aligns with other studies exploring the relationship between urban design and psychological well-being. Research from Valdivia, Chile, found that specific street design elements directly impact emotional states 6 .
That study identified that well-maintained facades with intense colors, spacious front gardens, wooden facades, low fences, wide sidewalks, and trees with colorful fruits and leaves promoted positive emotions like enjoyment, joy, and pleasure 6 . Conversely, neglected building facades, blind fronts with graffiti, high fences, tall buildings, treeless sidewalks, and poorly maintained pathways triggered negative emotions including fear, anger, discomfort, and stress 6 .
These findings reinforce the importance of the human-scale approach explored in the Amsterdam research. Both studies suggest that thoughtful design isn't merely an aesthetic concern but has real implications for mental health and community well-being.
| Street Design Element | Positive Examples | Negative Examples | Impact on Human Experience |
|---|---|---|---|
| Building Facades | Well-maintained, intense colors, architectural detail | Neglected, abandoned, blank walls | Colorful, maintained facades promote enjoyment; neglected ones cause discomfort 6 |
| Transition Spaces | Active plinths, terraces, transparent ground floors | Blank walls, inactive interfaces | Active transitions draw attention and create engagement 9 |
| Height-to-Width Ratio | Balanced proportions between buildings and street | Extremely tall buildings relative to street width | Poor proportions can cause stress and insecurity 6 |
| Natural Elements | Trees with colorful fruits/leaves, trimmed vegetation | Treeless sidewalks, untrimmed bushes | Vegetation promotes positive emotions; its absence diminishes well-being 6 |
| Visual Complexity | Oriental windows, colorful balconies, varied materials | Monotonous, repetitive facades | Architectural variety provides visual interest and wayfinding cues 9 |
The Scientist's Toolkit: Technologies Driving Streetscape Research
The innovative approach of the Sensing Streetscapes project relied on several key technologies and methodologies that allowed researchers to gain unprecedented insights into human experience of urban environments.
Artificial Intelligence
AI algorithms help analyze the vast amounts of data collected through eye-tracking and other methods, identifying patterns that might escape human observation 5 .
Urban Analytics
Quantitative analysis of spatial configurations, density measures, and physical properties of streetscapes provides the objective framework for understanding the physical environment 5 .
Participant Observation
Traditional observational methods complement the technological data, providing context and nuanced understanding of how people actually use spaces 9 .
This combination of emerging technologies with principles from both neuroscience and architecture represents what the researchers term "neuro-architecture" 5 —an emerging field that promises more evidence-based approaches to designing environments that promote human well-being.
Building the Cities of Our Future: Implications and Next Steps
The Sensing Streetscapes research comes at a critical time for cities worldwide. As urban areas continue to densify—with Amsterdam alone needing space for up to 90,000 new homes 3 —the question of how to maintain human scale and livability becomes increasingly urgent.
This research demonstrates that density and human-scale design need not be opposing forces. By understanding how people actually perceive and interact with their environment, we can develop more nuanced approaches to densification that accommodate necessary growth while preserving what makes cities enjoyable and healthy places to live.
Global Relevance
The implications extend far beyond Amsterdam. As the researchers note, densification is "currently accelerating in many Western cities" with high-rise living environments gaining ground as a dominant typology 3 . The insights from this study provide a framework for evaluating and improving these new urban forms.
Bridging Science and Design
What makes this research particularly significant is its potential to bridge the gap between scientific evidence and design practice. By providing objective data on human responses to different environments, it helps designers and planners make more informed decisions—creating streetscapes that don't just look good in renderings but actually feel good to the people who use them every day.
As cities continue to evolve and grow, research like Sensing Streetscapes reminds us that successful urbanism isn't just about numbers of housing units or square meters of park space—it's about creating environments that resonate with our human nature, that engage our senses, and that make us feel at home in an increasingly urban world.
