Abstract

fetched live from OpenAlex

Although fully implemented autonomous vehicles (AVs) seem to be on the cusp of reality, standard evaluation and testing procedures still are lacking. This study conducted a preliminary evaluation of the technical feasibility, safety, and reliability of using AV technology, in particular a low-speed, self-driving shuttle known as Olli. The study designed a set of 12 testing scenarios and performed experiments to evaluate the operational capabilities, safety, and reliability of the self-driving shuttle on the University at Buffalo’s Connected and Automated Vehicles (CAVs) proving grounds. The scenarios were designed to evaluate the vehicle’s performance while simulating the operational scenarios that the shuttle would encounter when deployed in the real world at a medical and educational campus in downtown Buffalo, New York. Preliminary results provide insight into the operational characteristics of the self-driving shuttle; its stopping distance behavior; its ability to detect and safely react to obstacles, conflicts, and other hazards on the road; its car-following behavior; and the impact of inclement weather conditions on performance.

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.
