Abstract

fetched live from OpenAlex

This study compares the changes in levels of accessibility over time in the Minneapolis -St.Paul region using two different modes (car and public transport).The importance of accessibility as a measure of land use and transportation planning performance in the region is revealed by comparing it over time.The longitudinal analysis being conducted shows increases in accessibility by car in most areas in the studied region, and a drop in accessibility by public transport over the period 1990 to 2000.The findings are compared to the levels of congestion in the region between the same time periods.This comparison shows the difference between the two measures and strengthens the importance of accessibility measures as a tool for monitoring and evaluating regional land use and transportation planning performance.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
