Driving, Fast or Slow? Neuro-Symbolic Guidance for Motion Prediction in Multi-Modal Ground Mobility

arXiv:2606.15251v1 Announce Type: cross Abstract: Accurate and interpretable motion prediction for heterogeneous traffic spaces, including pedestrians, bicycles, cars, and trucks, is essential for safe autonomous navigation. Nevertheless, state-of-the-art approaches remain predominantly black-box, lacking explicit encoding of the regulatory and behavioral constraints of real-world mobility. We propose Trajectory Compliance-Shaping (TraCS), a neuro-symbolic framework that augments existing black-box motion prediction backbones with interpretable and probabilistic first-order logic. To do so, Tr

Why this matters
Why now

The increasing complexity of autonomous systems and the need for explainability in safety-critical applications like self-driving necessitate hybrid AI approaches marrying symbolic and neural methods.

Why it’s important

This development offers a pathway to more reliable, auditable, and safer autonomous navigation, potentially accelerating the deployment and public acceptance of self-driving technology.

What changes

The explicit encoding of regulatory and behavioral constraints through neuro-symbolic AI shifts motion prediction from purely black-box to a more interpretable and compliant system.

Winners
  • · Autonomous vehicle developers
