Urban Biometric
Urban Biometric measures what public space is capable of — and what it is missing.
Why capacity, not use
Most urban data measures observed use: how many people walked, drove or cycled down a street. It is useful, and it is circular. A hostile street records little foot traffic, and little foot traffic reads as little demand — so the street is left as it is, and the measurement confirms itself.
Urban Biometric measures the other thing. Not what happened on the ground, but what the ground enables. Capacity and observed use are read separately, and the gap between them is the finding.
What it measures
Public space is read as one continuous urban plane — the ground between buildings, with material thickness and work to do — and graded against four conditions, drawn from E-UAS (ecological urban active surfaces), the framework published in Urbanistica Informazioni n. 329.
The first instrument reads streets. They are the largest piece of that plane and the most contested, and they are where the gap between what a city has and what it could have is widest. Plazas, waterfronts and the rest of the plane follow the same four conditions.
- E Ecological
- Participates in cycles of water, soil, climate and vegetation.
- A Active
- Receives, generates and transforms relationships — movement, staying, appropriation, changing programs.
- P Public
- Access, coexistence, encounter, collective agency.
- I Infrastructural
- Performs verifiable technical work, not scenery.
Measuring in metres rather than grid cells makes the reading independent of resolution, so a street in Boise and a street in Buenos Aires can be compared.
A segment is coded across its width and along its edge: what the ground is made of, what it drains and shades, how the frontage behaves, and how much of the width each mode holds.
What a city receives
A Street Profile — a panel of indicators, never collapsed into a single number — and a classification that names what is met and what is missing.
| L0 | Monofunctional | The plane serves one performance. |
| L1 | Multifunctional | Things are present; they do not relate. |
| L2 | Active | Functions co-perform on the same stretch. |
| L3* | Vital candidate | All four conditions met and integrated. Provisional. |
L1 · Multifunctional · P — not E, A, I
That label is legible to a city hall and to a neighbourhood association alike, and it names the target without prescribing the intervention. There is no score: the framework holds that these dimensions are not a universal scoring system and that vitality is relational rather than additive. A classification is a status, not a ranking.
Where it sits
- Measure
- Think
- Design
- Build
- Verify
The measurement stops at diagnosis, deliberately. What a public space lacks is handed to Studio, which argues, designs and builds the answer. Keeping the two apart is what makes the measurement worth trusting.
Where it stands
The first measurement is deliverable today, city-wide, from imagery and site survey. Verification over time is what the method is built for, and it requires a platform that does not exist yet — so it is a horizon, not a service on sale.
Every threshold is a placeholder until it is calibrated against observed activity on a real corridor. A classification is not a measurement until that is done, and we say so rather than let the two be confused. The first pilot is Boise, Idaho.
Urban Biometric reads the configuration of public space. It does not identify, track or profile people, and it collects no biometric data about anyone.
