Diffusion-Based Environment-Aware Trajectory Prediction
This addresses the problem of safe autonomous vehicle operation by providing more accurate and realistic trajectory predictions, though it appears incremental as an adaptation of diffusion models to this domain.
The paper tackles trajectory prediction for autonomous vehicles by proposing a diffusion-based generative model that captures multi-agent interactions and environmental constraints, achieving improved prediction accuracy over established methods on real-world datasets.
The ability to predict the future trajectories of traffic participants is crucial for the safe and efficient operation of autonomous vehicles. In this paper, a diffusion-based generative model for multi-agent trajectory prediction is proposed. The model is capable of capturing the complex interactions between traffic participants and the environment, accurately learning the multimodal nature of the data. The effectiveness of the approach is assessed on large-scale datasets of real-world traffic scenarios, showing that our model outperforms several well-established methods in terms of prediction accuracy. By the incorporation of differential motion constraints on the model output, we illustrate that our model is capable of generating a diverse set of realistic future trajectories. Through the use of an interaction-aware guidance signal, we further demonstrate that the model can be adapted to predict the behavior of less cooperative agents, emphasizing its practical applicability under uncertain traffic conditions.
