Abstract
The role of transit in aiding the implementation of regional land use plans that call for the creation of major diversified centers in the outer city is investigated. The polycentric city concept is defined and illustrated by reference to regional planning work in the Twin Cities of Minnesota and several other U.S. cities. Arguments for and against the concept are outlined and the results of a survey relating to the present status of the concept in 48 metropolitan areas are presented. An evaluation framework is developed and applied in visits to 14 American, two Canadian, and one English urban region. The most interesting work on this topic was found in Vancouver, B.C., and Toronto, Ontario. Other interesting work has been done in the Twin Cities and Denver. The results of the field work are summarized and 18 specific examples of noteworthy progress toward the development of outer city centers of significant scale are described. A discussion of the national potential for outer city centers is developed from several perspectives.

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.
