Abstract

fetched live from OpenAlex

I denna rapport redovisas internationella erfarenheter av upphandling av avhjälpande vägunderhåll. Studien beskriver upphandlingsförfarandet i Norge, Skottland och Ontario (Kanada) samt resultat från relevant litteratur. Genomgångarna har fokuserats på skillnaden i effektivitet mellan utförarkontrakt och funktionskontrakt samt hur incitament, riskfördelning, konkurrenssituation och kvalitetsdimensioner påverkar utfallet av kontrakten. Resultaten pekar på att Ontario och Norge utgår från funktionskontrakt. Under senare tid har vissa aspekter av dessa kontrakt omprövats då problem har uppstått främst i vinterunderhållet. I Ontario vägs nu kvalitet in i anbudsprocessen och i Norge används en ny ersättningsmodell som avser att balansera negativa incitament. I Norge testas även nya kontraktsmodeller på fem platser i landet. Skottland använder utförarkontrakt och har under senare tid utprovat indikatorer för att fånga kvaliteten på vinterunderhåll genom att använda friktionsmätning. I litteraturen finns ofta en positiv grundsyn på funktionskontrakt. Ingen studie har dock påträffats som mäter effektiviseringar till följd av en viss kontraktsmodell där hänsyn tas till eventuella samtidiga effekter i kvalitet eller kontraktsmodellens långsiktiga påverkan.

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.
