Abstract

fetched live from OpenAlex

La prévalence de l’usage du cannabis et celle de la conduite sous l’influence du cannabis présentent une évolution à la hausse au Canada. En conséquence, il importe d’étudier les effets délétères de cette substance psychoactive (SPA) sur la sécurité routière. La présente étude a pour objectif d’évaluer les liens entre l’usage de cannabis et la conduite automobile dangereuse auprès d’un échantillon de conducteurs québécois. Des analyses de régressions linéaires hiérarchiques mettent en évidence l’importance de l’usage de cannabis comme facteur de prédiction de la prise de risque sur la route et de l’agressivité au volant, même après le contrôle statistique de l’âge, du genre et de l’exposition à la conduite. Des analyses de régressions logistiques indiquent que l’usage de cannabis est associé à une augmentation du risque de recevoir une contravention découlant d’une infraction au Code de la sécurité routière. De plus, il semble que l’usage occasionnel de cannabis chez les individus âgés de 35 ans et plus est associé à un risque plus élevé d’être impliqué dans une collision. L’ensemble des résultats indique que l’usage de cannabis et la conduite automobile dangereuse sont interreliés, ce qui appuie la théorie du comportement « à problèmes ».

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.
