On Urban Form and Accessibility to Fresh Food: An Enquiry into the Spatial Distribution of Fresh Food Retail Establishments, in Relation to Transportation Networks and the Built Environment: \nA Montreal Case Study
Bibliographic record
Abstract
This thesis discusses the relationship between urban form and accessibility to fresh food in Montreal. Anchored in the disciplines of urban morphology and retail geography, it mobilizes GIS-based spatial and network analysis, as well as methods for measuring travel times by transportation modes. Establishments selling fresh fruits and vegetables are used as a proxy for healthy and nutritious food retailing. A three-pronged analysis is performed that looks into the establishments’ spatial distribution; the physical and spatial characteristics of their surroundings; and their accessibility by active and collective transportation modes. A morphological approach reveals fine spatial articulations between retail location and specific characteristics and properties of the urban system, including its transportation infrastructures. The importance of accessibility to fresh food on public health cannot be over-emphasized. Furthermore, a supply system that reduces automobile dependence is a crucial step towards social and environmental sustainability and equitability.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
