Abstract

fetched live from OpenAlex

Automatic train operation (ATO) is a relatively new trend in heavy rail. While technical specifications define system and function requirements, implementation and adoption of ATO requires a business case. In this research we have developed a framework which could indicate if a corridor is suitable for automatic operation or not. We have approached this challenge by using product development methods such as QFD (Quality Function Deployment) and methods developed specifically for this study. The results indicate that ATO could influence performance, time to market and costs with respect to manual operation. The influence depends on the characteristics of a corridor, corridor segmenting as well as the operational procedures. The positive influence of ATO, considering the current state of the Dutch railways, could be limited and there may be additional challenges.

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.
