Abstract

fetched live from OpenAlex

Investigation of pedestrian-cyclist interactions is important for understanding both objective risks and traveler comfort. There is a lack of clear understanding of conflicts between pedestrians and cyclists, as they result in few reported incidents or injuries. More research is needed on the frequency and causes of pedestrian-cyclist incidents, and how those incidents affect the comfort and perceived safety of travelers by each mode. The objectives of this research were 1) to investigate the relationship between expressed safety concerns and experienced incidents for travelers in a high-volume non-motorized shared space, and 2) to examine primary factors in pedestrian-cyclist incidents. Data were acquired from an intercept survey of 337 travelers conducted on a large university campus. Results reveal a high frequency of incidents with physical contact between people walking and cycling, consistently described by each, which led to few injuries but verified the expressed concerns of survey participants and anecdotal reporting to the campus transportation agency. Prior experience of an incident was a significant factor influencing perceptions of safety. Cyclists were at least as concerned about intermodal conflicts and safety as pedestrians and preferred to avoid pedestrian-dominated areas, but that preference was weighed against travel time, ease of wayfinding, and avoidance of motor vehicles. Both pedestrians and cyclists identified crowding and pedestrian inattention as major contributing factors to incidents, but they disagreed on whether cyclist speed was a factor. Potential strategies to reduce intermodal conflicts in shared spaces include reducing crowding, separating modes, and reducing cycling speeds.

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.
