Abstract

fetched live from OpenAlex

This report documents the CACC implementation and field tests for Class-8 trucks. The CACC system design for this implementation has been documented in a separate report. The field tests include two types: some limited freeway tests for control system tuning and development purposes, and extensive tests of fuel consumption at Transport Canada’s Motor Vehicle Test Centre near Montreal. Although the objective of the latter test was for fuel economy analysis of CACC operations, the data have been used for CACC performance analysis in this report since most of the fundamental scenarios have been tested systematically.

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.
