Abstract
The concept of the transshipment of goods has not been widely incorporated into models for transportation planning. A model with transshipment should recognize that a whole shipment could be transported in two or more stages involving intermediate points (transshipment points) between the origin and the final destination. The database containing data from the Ontario, Canada, Commercial Vehicle Survey is one of the few databases that contains substantial transshipment information. The analysis of the Ontario Commercial Vehicle Survey first focused on commodities and their origin–destination facilities and defined terminals and warehouses as possible transshipment locations. Analysis revealed that any commodity was likely to be transshipped through either a truck terminal or a warehouse. Eight tour structures could be ascertained from the database, with each structure differing in the order and number of transshipment points and previous customers. A choice model of those tour structures was built. Factors such as commodity type, origin–destination facility type, truck type, distance, and shipment size were significant, depending on the structure.

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.
