Houston Is On The Right Side Of The Tracks
Bibliographic record
Abstract
Houston, Texas has long been plagued by urban and suburban sprawl. Political leadership in Houston has worked hard to improve the economy using several levers available to them. One area the city attempts to improve is that of public transit. The city has developed a large fixed-rail transit system in separate stages since 2004 when the first 7.5 mile stretch of the Harris County Metropolitan Authority fixed light rail, the METRORail, opened. The system has since grown, mostly Eastward, to 22.7 miles and 34 stations, with further expansion planned. I use data on real estate values and property characteristics provided by Harris County Appraisal District and Geographical Information Systems data to determine whether the rail system has had an impact on housing values or urban density. Evidence in the data supports that the latest generation of transit stations has contributed to increased housing values in the areas surrounding the transit stations as compared to the rest of Houston. There is also evidence in housing data that identifies a broad increase for demand across Houston with a more pronounced increase in demand for density around the transit stations.

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.
