论文摘要
尽管自动驾驶汽车在公路驾驶过程中仍在努力解决具有挑战性的情况,但人类长期以来一直以高效,可转移和适应性的驾驶能力掌握了驾驶的本质。通过模仿人类在驾驶过程中的认知模型和语义理解,我们提出了HATN,这是一个层次结构框架,用于在多代理繁客交通环境中产生高质量,可转移和适应性的预测。我们的分层方法包括高级意图识别政策和低级轨迹生成政策。我们引入了每个子任务的新型语义子任务定义和通用状态表示。通过这些技术,分层框架可以在不同的驾驶场景中转移。此外,我们的模型能够通过在线适应模块捕获个人和方案之间的驾驶行为的变化。我们在交互数据集的交叉点和回旋处的真实流量数据的轨迹预测任务中演示了我们的算法。通过广泛的数值研究,很明显,我们的方法在预测准确性,可传递性和适应性方面显着优于其他方法。通过相当大的利润来推动最先进的绩效,我们还提供了一种认知观点,可以理解这种改进背后的驾驶行为。我们强调,将来,应有更多的研究关注和努力,以使其可转移性和适应性。这不仅是由于预测和计划算法的表现提高了,而且从根本上讲,它们对于自动驾驶汽车的可扩展和一般部署至关重要。
While autonomous vehicles still struggle to solve challenging situations during on-road driving, humans have long mastered the essence of driving with efficient, transferable, and adaptable driving capability. By mimicking humans' cognition model and semantic understanding during driving, we propose HATN, a hierarchical framework to generate high-quality, transferable, and adaptable predictions for driving behaviors in multi-agent dense-traffic environments. Our hierarchical method consists of a high-level intention identification policy and a low-level trajectory generation policy. We introduce a novel semantic sub-task definition and generic state representation for each sub-task. With these techniques, the hierarchical framework is transferable across different driving scenarios. Besides, our model is able to capture variations of driving behaviors among individuals and scenarios by an online adaptation module. We demonstrate our algorithms in the task of trajectory prediction for real traffic data at intersections and roundabouts from the INTERACTION dataset. Through extensive numerical studies, it is evident that our method significantly outperformed other methods in terms of prediction accuracy, transferability, and adaptability. Pushing the state-of-the-art performance by a considerable margin, we also provide a cognitive view of understanding the driving behavior behind such improvement. We highlight that in the future, more research attention and effort are deserved for transferability and adaptability. It is not only due to the promising performance elevation of prediction and planning algorithms, but more fundamentally, they are crucial for the scalable and general deployment of autonomous vehicles.
