Abstract

fetched live from OpenAlex

This project developed an integrated Global Positioning System–geographic information system (GPS-GIS) to automate the processing of GPS-based personal travel survey data. Two versions of the analysis system were developed in this project: a GPS-alone system, which uses only GPS travel data as input, and a GPS-GIS integrated system, which uses both GPS travel data and topologic information on GIS platform as input. The GPS-alone system includes an activity identification algorithm and a fuzzy logic–based mode identification algorithm. The GPS-GIS integrated system includes link identification on a GIS platform as well as an interactive link matching-mode identification subsystem, which further refines the results from previous identifications performed separately. This project demonstrates how GPS travel data analysis can be automated and highlights the benefits brought by an interactive analysis system, providing an innovative analysis method for personal-based GPS multimodal travel surveys.

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.
