Traffic flow controlled by synchronized traffic lights in an open and periodic boundaries system
Bibliographic record
Abstract
The traffic flow controlled by synchronized traffic lights on a single-lane roadway with open and periodic boundaries is studied. This study is based on a modified version of the Nagel and Schreckenberg (NaSch) (J. Phys. 1 (France), 2, 2221 (1992)) model recently proposed by Zhu et al. (Eur. Phys. J. B, 57, 103 (2007)) in parallel dynamics, which takes into account the sensitivity of drivers and vehicles. Five traffic lights are placed on the road at equal distances and are synchronized with a cycle time T. The density, flow, and (α, β) phase diagrams are established for different values of T, where α and β are the injecting and extracting rates, respectively, of cars in the traffic lane. In the deterministic NaSch model, the presence of signal lights on the road causes early onset of the high-density region. Additionally, it is shown that the low-density region shrinks with an increase in T, when T is less than a certain value. However, the modified NaSch model shows that the low density phase shrinks even more. Finally, in the presence of traffic lights, a comparison is made between the original NaSch model with a constant braking probability and the modified one.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
