The urban right to AI: Pluralistic co-design and governance of public space

This thesis develops a civic 'Right to AI' framework and two empirical tools tested in Montreal to govern public space algorithms. The Street Review tool combines participatory research with computer vision to map resident evaluations of streets using 45,000 street-view images, while the LIVS dataset compiles 37,710 pairwise comparisons across 13,462 images with 30 community organizations to fine-tune a Stable Diffusion XL model. The resulting framework translates these pluralistic evaluations into municipal governance practices, including procurement rules, oversight, and recourse mechanisms.

Why it matters — It establishes a method for municipal AI governance that treats public disagreement and value differences as valid, persistent evidence rather than as annotation noise or measurement error to be averaged out.

Caveat: The empirical applications and participatory datasets are grounded in the specific local context of Montreal, which may limit how directly the specific model alignments transfer to other cities.

Signal Timing Optimization for Mixed Connected Automated Traffic Based on a Markov Delay Approximation

The paper develops an analytical framework to approximate intersection delay and calculate optimal signal cycle lengths for mixed traffic containing both connected automated vehicles (CAVs) and human-driven vehicles (HDVs). The model integrates Markov chain analysis, a car-following model, and queuing theory to mathematically account for the distinct arrival, departure, and headway behaviors of both vehicle types.

Why it matters — It provides closed-form mathematical expressions for mixed-traffic intersection delays, replacing complex simulations with a tractable analytical tool that traffic engineers can use to optimize signal timing as autonomous vehicles are gradually deployed.

Caveat: The mathematical model is validated only through numerical experiments at a single, isolated intersection rather than using empirical field data or network-wide simulations.

Insights into spatial accessibility of primary healthcare in the Cape Town District, South Africa

This study models walking and driving travel times and distances to public primary healthcare centres across the Cape Town District using Geographic Information Systems. It finds that while 82.89% of the population can reach a facility within one hour, meeting operational standards depends heavily on having access to a car. The outer health planning regions (Western, Southern, Northern, and Eastern) exhibit the poorest accessibility, disproportionately affecting Black African residents compared to Coloured and white populations.

Why it matters — The study quantifies how Cape Town's historical spatial structure translates into modern healthcare disparities, demonstrating that public transit and walking infrastructure are currently insufficient to meet healthcare access standards without private vehicle ownership.

Caveat: The analysis is conducted at a regional district scale, which may mask finer-grained accessibility disparities at the individual suburb level.

Policy coherence in mixed-use development and its implications for sustainable urban development

This study analyzed nine national policy documents in Ghana to assess policy coherence for mixed-use development across five drivers and four implementation dimensions. The analysis revealed only partial alignment, with stronger coherence around land-use efficiency and compact-development goals, but significant gaps in institutional coordination, financing, monitoring systems, affordable housing, active mobility, and transport-land use integration.

Why it matters — It demonstrates that policy incoherence in rapidly urbanizing contexts is not merely a sectoral issue but an institutional and political challenge shaped by fragmented mandates and the friction between statutory planning and plural land tenure systems.

Caveat: The study relies on a qualitative content analysis of national-level policy documents rather than evaluating municipal-level implementation or physical urban outcomes.

Governance and data readiness as prerequisites for digital twin adoption in small and midsize cities

The paper introduces the Foundation First framework, a four-phase conceptual readiness pathway designed to help small and midsize cities prepare for digital twin deployment. The framework sequences municipal progress through foundational inventory, integration, predictive pilots, and sustainable intelligence, and is illustrated using the data governance and asset management practices of Sugar Land, Texas.

Why it matters — It shifts the evaluation of digital twin readiness away from purely technical sophistication toward sequential governance controls, data integrity, and public trust. This provides resource-constrained municipal leaders with a structured method to assess if their administration is actually prepared for advanced urban intelligence investments before purchasing technology.

Caveat: The framework is conceptual and illustrated using a single midsize municipality that has established data governance but has not yet deployed a digital twin platform.

A systematic review of eye-tracking methods for studying visual attention in urban public spaces

This systematic review synthesized 73 primary empirical studies and 3 reviews published between 2015 and 2025 to evaluate eye-tracking methodologies in urban public spaces. Using PRISMA guidelines, the study appraised research quality, mapped analytical pipelines for raw gaze data, and evaluated reporting completeness across devices, sample sizes, and spatial indicators.

Why it matters — It establishes a standardized methodological recommendation for transforming raw gaze data into spatially interpretable behavioral metrics, while identifying critical gaps in current research such as nighttime environments and culturally sensitive urban contexts.

Caveat: The review notes that while most of the evaluated studies are methodologically sound in their design, they frequently suffer from incomplete reporting of their eye-tracking procedures.

Spatiotemporal organization in bike-sharing systems using gravity model parameters

This study analyzes temporal and spatial variations in gravity model parameters—specifically origin, destination, and distance exponents, alongside R-squared and mean absolute error—across eight bike-sharing systems. Using sliding temporal windows and expanding circular spatial zones, the research evaluates how these parameters fluctuate throughout the day and across different trip types, including intra-zonal, cross-zonal, and extra-zonal flows.

Why it matters — It demonstrates that standard citywide, full-day gravity model fits conflate distinct temporal and spatial flow dynamics, proving that bike-sharing models must separate peak hours and specific zone boundaries to accurately predict trip distribution.

Climate change and human mobility will shape dengue emergence risk in Europe

An integrated, multi-scale model was developed to project dengue emergence risk across Europe throughout the 21st century by combining a mechanistic transmission engine, a vector abundance framework, and a mobility-driven metapopulation system. The model incorporates climate projections, population forecasts, air-traffic data, and a dedicated migration model that accounts for climate-driven human redistribution. The simulations show a substantial increase in risk indicators under most emissions scenarios, indicating a gradual transition from import-driven transmission to an environment-driven regime under the worst-case emissions scenario.

Why it matters — The model establishes a quantitative link between climate-driven human migration and vector-borne disease transmission, providing a predictive capability to identify which European populations will face local outbreaks under shifting environmental conditions.

PlaceSeek: Human-Centered Geospatial Retrieval of Urban Outdoor Places via Semantic Grounding and Affective Alignment

The researchers developed PlaceSeek, a geospatial retrieval framework that matches natural-language queries to geolocated street-view imagery by analyzing both functional and affective user intents. The system uses a Semantic Grounding Module to verify physical features and a LoRA-adapted vision-language model to rank candidates based on human perception. Tested on 31,956 street-view locations in Milan across 10 queries, the framework achieved an 88.0% Precision@5 and a 0.920 nDCG@5, outperforming CLIP and SigLIP baselines.

Why it matters — It shifts geospatial search from rigid, metadata-driven point-of-interest queries to flexible, human-centered searches based on activities and emotional perceptions. This enables search engines to reliably find urban spaces that match complex, subjective descriptions like 'peaceful places for reading' by verifying both physical suitability and visual atmosphere.

Caveat: The framework's performance and human evaluation are based on a single European city, Milan, which may limit its immediate generalizability to cities with different architectural styles and urban layouts.

Bayesian spatio-temporal exposure modelling of air pollution in Rome, Italy, and short-term effects on cause-specific mortality

The study developed a Bayesian spatio-temporal model to predict daily concentrations of NO2, PM10, and PM2.5 across Rome, Italy, at a 1 km resolution from 2011 to 2022 using data from 8 to 13 monitoring stations. These daily exposure estimates were linked to geolocated cause-specific mortality data from 2012 to 2019 using a case-crossover design, finding that a 10 Αg/m3 increase in PM2.5, NO2, and PM10 (mean lag 0-5) was associated with natural-cause mortality increases of 2.4%, 2.1%, and 1.3% respectively.

Why it matters — It demonstrates that a high-resolution 1 km exposure model yields mortality risk estimates of comparable magnitude to those derived from simple city-wide daily averages, while providing a reliable framework for fine-scale urban environmental epidemiology.

Caveat: The predictive model exhibited larger estimation errors at high-traffic monitoring sites.
