Abstract
The current study examines the possibility of automatically detecting distracted pedestrians on crosswalks using their gait parameters. The methodology utilises recent findings in health science concerning the relationship between walking gait behaviour and cognitive abilities. Walking speed and gait variability are shown to be affected by the complexity of tasks (e.g. texting) that are performed during walking. Experiments are performed on a video data set from Surrey, British Columbia. The analysis relies on automated video‐based data collection using computer vision. A sensitivity analysis is carried out to assess the quality of the selected features in improving the accuracy of the classification. Classification results show that the proposed approach is promising with around 80% correct detection rate. This research can benefit applications in several transportation related fields such as pedestrian facility planning, pedestrian simulation models as well as road safety programmes and legislative studies.

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 it
