Abstract

fetched live from OpenAlex

By applying the concept of information entropy in the information theory, this study aims to create a complexity index to measure the driver-perceived driving environment and to give remedy for the past indexes’ incapability of showing drivers’ perceived comfort and safety. The complexity index is calculated by the drivers’ driving behaviors of speed, acceleration and deceleration, and horizontal shift area. We show that the complexity index is a proper qualitative index to truly reflect the drivers’ perception of driving environment and to measure the level of service. It can be a supplement index for the traditional traffic measures.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
