Abstract

fetched live from OpenAlex

Les relations entre transports ferroviaire et fluvial ont surtout été envisagées sous l'angle de l'impitoyable concurrence à laquelle se sont livrés les deux modes pour le transport de masse. Aujourd'hui toutefois, un intérêt croissant est porté à leur éventuelle complémentarité. Ce discours encore émergent est porté aussi bien par les grands opérateurs de transport dans le couloir de la Seine que par les autorités portuaires qui ont hérité d'installations ferroviaires portuaires. Le rapprochement des deux modes est aussi vivement encouragé par les autorités publiques avec pour ambition de faire jouer aux ports un rôle de plateformes multimodales en cohérence avec une politique de transfert modal. Après avoir rappelé les éléments contextuels, cette contribution qui s'inscrit dans une perspective d'aménagement cherche à établir les possibles complémentarités des modes fluvial et ferroviaire dans le cadre des ports franciliens dont la gestion a été confiée à Ports de Paris en 2012.

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.
