Abstract

fetched live from OpenAlex

Artificial intelligence (AI) methods have been frequently employed to solve complicated control and optimization problems in many different disciplines. Traffic signal control and optimization is no exception. A wide range of AI methods have been introduced into this area to develop innovative traffic control strategies and fine tune signal timing plans and parameters. These AI applications are summarized into the following four categories and detailed in this article: evolutionary algorithms, fuzzy logic control, artificial neural networks control, and reinforcement learning and agent-based control.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
