摘要:

本文提出了一种自动驾驶汽车的驾驶员特定的风险识别框架,可以提取车辆间的相互作用。这种提取是在驾驶员认知的方式进行城市驾驶场景,以提高识别准确率的危险场景。首先,对驾驶员的操作数据进行聚类分析,学习不同驾驶员对危险场景的主观评价,并为每个场景生成相应的风险标签。其次,采用图表示模型(GRM),将真实驾驶场景中的动态车辆、车辆间交互和静态交通标记的特征统一构造成图。特定于驾驶员的风险标签提供了基础事实,以捕获不同驾驶员的风险评估标准。此外,图模型表示驾驶场景的多个特征。因此,所提出的框架可以学习不同驾驶员的驾驶场景的风险评估模式,并建立特定于驾驶员的风险标识符。最后,所提出的框架的性能进行了评估,通过实验进行使用真实世界的城市驾驶数据集收集的多个驱动程序。结果表明,该框架可以准确地识别实际驾驶环境中的风险及其水平。

英文摘要:

This paper presents a driver-specific risk recognition framework for autonomous vehicles that can extract inter-vehicle interactions. This extraction is carried out for urban driving scenarios in a driver-cognitive manner to improve the recognition accuracy of risky scenes. First, clustering analysis is applied to the operation data of drivers for learning the subjective assessment of risky scenes of different drivers and generating the corresponding risk label for each scene. Second, the graph representation model (GRM) is adopted to unify and construct the features of dynamic vehicles, inter-vehicle interactions and static traffic markings in real driving scenes into graphs. The driver-specific risk label provides ground truth to capture the risk evaluation criteria of different drivers. In addition, the graph model represents multiple features of the driving scenes. Therefore, the proposed framework can learn the risk-evaluating pattern of driving scenes of different drivers and establish driver-specific risk identifiers. Last, the performance of the proposed framework is evaluated via experiments conducted using real-world urban driving datasets collected by multiple drivers. The results show that the risks and their levels in real driving environments can be accurately recognized by the proposed framework.
