Thesis: Urban Quality in the Experiential City

Claim: The most livable cities balance efficiency (structured access) and serendipity (unplanned, meaningful experiences), especially in a post-COVID context where work decentralizes and everyday experience becomes central to urban value.

Gap

Most urban design frameworks (e.g. 15-minute city) optimize for efficiency but neglect serendipity.

There is no operationalized, data-driven way to measure or map serendipity at scale.

The emerging “experiential city” demands new metrics that account for pleasure, discovery, ambiguity, and play.

Hypothesis

Urban well-being emerges from a dynamic balance between efficiency and serendipity.

Cities over-optimized for proximity and predictability lose the social and creative value that comes from structured unpredictability.

Theoretical Foundations

Jon Kleinberg: navigable systems require a balance of local links (efficiency) and long-range randomness (serendipity).

Jane Jacobs, William Whyte: complexity and spontaneity as civic virtues.

Urban morphologies (CNU, space syntax): form constrains or enables experiential sequences.

Post-COVID shift: city as platform for culture, leisure, learning—not just work.

Place typologies: importance of 1.5 and 2.5 places as zones of porousness and hybrid use.

Method Overview

Define and operationalize two axes of urban quality:

Efficiency: proximity to amenities, transit coverage, walkability (using OSM, GTFS, Walk Score, etc.)

Serendipity: POI diversity, semantic adjacency, ambiguous use, temporal variance, street network entropy

Use publicly available or purchasable datasets:

OpenStreetMap

SafeGraph / Veraset / Cuebiq

Yelp, Foursquare, Google Places

GTFS feeds and transit APIs

Facebook or Eventbrite event data

Map and score neighborhoods on both axes

Identify spatial typologies and performance quadrants:

High-efficiency / high-serendipity

High-efficiency / low-serendipity

Low-efficiency / high-serendipity

Low-low zones

Analyze across scales: block, neighborhood, district

Interpret role of 1.5 / 2.5 places in enabling rich experience

Expected Contributions

A reproducible framework to measure and compare urban serendipity

A new way to conceptualize and design for quality in the experiential city

Grounded recommendations for planners to support both accessibility and spontaneous urban joy
