LAMP: Lane-Aligned Motion Primitives for Feasible Trajectory Prediction

arXiv:2606.26661v1 Announce Type: cross Abstract: Motion forecasting is essential for autonomous driving systems to enable safe decision-making and planning in complex driving scenarios. While existing predictors excel at minimizing standard displacement errors, they often overlook the adherence to lane topology of multimodal predictions, particularly for lower-probability modes. Consequently, predicted trajectories may violate physical and logical constraints, making the prediction set unreliable for safety-critical planning. In this paper, we propose LAMP (Lane-Aligned Motion Primitives), a

Why this matters
Why now

The rapid advancement in AI and robotics research necessitates more robust and reliable trajectory prediction for real-world autonomous systems, especially as autonomous driving moves closer to widespread adoption.

Why it’s important

Improved trajectory prediction, particularly concerning physical and logical constraints, is critical for safety and reliability in autonomous systems, directly influencing their deployment and public acceptance.

What changes

Autonomous driving systems can now incorporate more reliable and lane-aligned motion predictions, reducing the risk of unsafe trajectories and improving decision-making in complex environments.
