Abstract
Highway geometric design plays a crucial role in maintaining traffic safety and operational efficiency. The number of Autonomous Vehicles (AVs) and Connected Autonomous Vehicles (CAVs) on highway networks has increased in recent years. In this study, a traffic model is developed from a spring-mass system theory perspective to investigate traffic dynamics on horizontal highway curves. The Intelligent Driver (ID) model is based on a constant exponent δ to characterize driver response, which is unrealistic. By utilizing a spring-mass system analogy, the proposed model provides a more accurate and realistic representation of traffic. This model is used to evaluate the behavior of Human-driven Vehicles (HVs), AVs, and CAVs over a 1300 m circular road. The results obtained show that CAVs have better performance compared to HVs and AVs on horizontal curves, leading to better understanding of safety and efficiency on roads. Further, CAVs improve energy efficiency and emission reduction, contributing to effective and sustainable transportation systems. In addition, the results indicate that the proposed model has better performance compared to the ID model.

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
