Abstract

fetched live from OpenAlex

In many cities in China, the problems of low efficiency and pedestrian risk taking at signalized intersections are mainly attributed to pedestrian red-time crossing. Pedestrian red-time crossing has many causes, such as traffic design and signal control, traffic flow, and the psychology of pedestrians’ decision making. In this study, data were collected on pedestrian red-time crossing, signal control, crossing facility design, and vehicle traffic flow with field observations and on pedestrians’ decision-making psychology data by using an intercept questionnaire administered after the crossing. A model for pedestrian red-time crossing choice was proposed on the basis of integrated field observations and questionnaire data. The model was compared with models based on either observational data alone or questionnaire data alone and proved to be well fit and to yield better prediction accuracy. The duration of red signal time was found to be the biggest influence on pedestrian red-time crossing. Suggestions for intersection design and signal control are proposed on the basis of these findings. Model building and data collection methods of pedestrian red-time crossing are also discussed.

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.
