Abstract

fetched live from OpenAlex

As society moves closer to fully autonomous vehicles, it must eventually make vehicles work together. This would reduce traffic jams, reduce cost of trips, reduce overall travel time, reduce the environmental impact, and reduce the number of casualties to traffic. [1] However, society's focus has mostly gone towards making the vehicles autonomous and not towards making a system that would manage a set of robo-taxis. This gap in research should be thoroughly explored because although autonomous vehicles are safer, they are not necessarily more efficient in reducing traffic jams and the cost of trips. [6] There have been many promising studies in tackling individual issues that such a system would face. These include finding an efficient route from point A to point B [2, 3], optimizing intersections [4], tackling road hazards [6], and more. By combining many preexisting algorithms into one system, Celer attempts to optimize traffic flow in New York City and explore the problem of car interconnectivity. Celer is able to reconstruct a map of New York City and uses taxi data from 2015 to simulate real world conditions. Overall, Celer improved trip time and profits substantially and showed a promising solution to the fleet management problem.

Full frame distilled prediction

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.
