Abstract
The significant growth of many urban areas comes at a cost of increasing demand for mobility and traffic congestion in large-scale urban environments. As congestion levels soar to unprecedented levels, and researchers and governments are challenged addressing the basic needs for transportation and mobility; solutions are becoming more complex and untraditional, creating a strong potential for optimization and simulation of large-scale transportation networks. In this paper, we present a generic traffic management framework for solving large-scale constraint optimization problems in advanced Intelligent Transportation systems (ITS) applications. The framework employs a distributed computing approach to enable replicating analysis of large-scale traffic simulation networks, providing a practical mechanism for solving complex optimization problems in transportation applications. We discuss employing the framework in two use cases, congestion pricing and emergency evacuation, targeting optimization of spatial and temporal traffic management.

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
