Abstract

fetched live from OpenAlex

The design of the geometry and traffic controls at signalised junctions is often focused on the level of service offered to motor vehicles and rarely considers the level of service offered to pedestrians. This results in pedestrians adopting illegal and unsafe behaviours – for example, red-light violation. This study aimed to identify the elements of signalised junction design that are critical in pedestrian safety by analysing how they affect pedestrian behaviour. Both traffic engineering design and associated traffic conditions were investigated. Over 6500 observations were made at ten signalised junctions in Montreal, Canada. The ten junctions were selected to cover a variety of environments, road users and junction designs. The results show that the presence of a countdown display has the most significant and positive impact on pedestrian behaviour. The results also suggest that pedestrians cross on the red light when they feel confident about their ability to judge whether they can use the available traffic gaps to cross the street safely. This study concludes that an adequate junction design is likely to limit risky pedestrian behaviours. Therefore, designers need to consider the factors affecting the behaviour of pedestrians to design junctions that are convenient and safe for them.

Teacher imitation

Not 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.
