Parameters for a Roll On-Roll Off Marine Intermodal Service on Lake Superior
Bibliographic record
Abstract
The feasibility of reestablishing roll on–roll off (RO–RO) service linking Thunder Bay, Ontario, and the Twin Ports of Duluth, Minnesota, and Superior, Wisconsin, was examined. An analysis of similar services both on the Great Lakes and overseas was undertaken. Previous operations on the same route on Lake Superior and short sea service in the Baltic region were analyzed, and the attributes of an appropriate vessel type, such as ice strengthened scantlings and adequate speeds, were determined. A route schedule for a typical vessel was developed. A profile of a suitable vessel was prepared, and the market availability of the vessels was assessed. Issues in terminal design and operation were applied to potential docks in the ports of call to determine the adequacy of shoreside facilities. Cost factors for vessel operations and terminal operations were determined, and a spreadsheet model was developed for future application. Potential revenue streams from vessel and terminal operations were also explored. Revenue generators included day passengers as well as trailers and containers. The feasibility of linking the RO–RO service to a larger intermodal system serving Canada and the United States was also assessed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
