Real-World Impact: Enhancing Autonomous Driving Systems

The TrajMoE framework directly addresses critical challenges in autonomous driving by moving beyond fixed trajectory vocabularies. Traditional systems often struggled with diverse scenarios, leading to suboptimal planning. TrajMoE introduces a sparse Mixture of Experts (MoE) to provide scenario-adaptive trajectory priors, ensuring that the system can intelligently select the most appropriate planning strategies for various driving conditions (e.g., straight vs. turning). This adaptability is crucial for robust real-world deployment.

Furthermore, the integration of Reinforcement Learning (RL) through the GRPO strategy fine-tunes the trajectory scoring mechanism. This policy-driven refinement significantly improves the model's ability to accurately predict driving scores, moving beyond the limitations of one-stage supervised training. By ensembling models with different perception backbones, TrajMoE achieves a comprehensive understanding of the scene, leading to safer and more reliable planned trajectories. Its 3rd place finish on the competitive navsim ICCV benchmark validates its potential to contribute to the next generation of highly capable autonomous vehicles, reducing risks and improving overall operational efficiency.
