Abstract

fetched live from OpenAlex

In this paper, we present a convex-optimization-based method to solve speed planning problems over a fixed path for autonomous driving in both static and dynamic environments. Our contributions are twofold. First, we introduce a general, flexible and complete speed planning optimization which includes time efficiency, smoothness objectives and dynamics, friction circle, boundary condition constraints which addresses limitations of existing methods and is able to provide smooth, safety-guaranteed, dynamically-feasible, and time-efficient speed profiles. Second, we demonstrate that our problem preserves convexity with the expanded set of constraints, and hence, global optimality of solutions is guaranteed. We show how our formulation can be used in speed planning for various autonomous driving scenarios by providing several typical case studies in both static and dynamic environments. The results depict that the proposed method outperforms existing speed planners for autonomous driving in terms of capacity, optimality, safety and mobility.

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.
