摘要:

多车辆交互行为分类和分析提供了深入的知识,为自动驾驶车辆做出有效的决策。本文的目的是聚类的驾驶遭遇的情况下,仅基于多车辆GPS轨迹的范围广泛。为此,我们提出了一个通用的无监督学习框架,包括两层:特征表示层和聚类层。在特征表示层中,我们将深度自动编码器与基于距离的度量相结合,将驾驶遭遇的顺序观察映射到一个计算上易于处理的空间中,该空间允许量化两辆车的时空交互特征。聚类算法,然后应用到所提取的表示收集同质的驾驶遇到成组。我们提出的通用框架,然后使用2,568自然驾驶遭遇进行评估。实验结果表明,我们提出的通用框架结合无监督学习可以聚类多轨迹数据到不同的群体。这些聚类结果可以为自主车辆的决策分析和设计提供参考。

英文摘要:

Multi-vehicle interaction behavior classification and analysis offer in-depth knowledge to make an efficient decision for autonomous vehicles. This paper aims to cluster a wide range of driving encounter scenarios based only on multi-vehicle GPS trajectories. Towards this end, we propose a generic unsupervised learning framework comprising two layers: feature representation layer and clustering layer. In the layer of feature representation, we combine the deep autoencoders with a distance-based measure to map the sequential observations of driving encounters into a computationally tractable space that allows quantifying the spatiotemporal interaction characteristics of two vehicles. The clustering algorithm is then applied to the extracted representations to gather homogeneous driving encounters into groups. Our proposed generic framework is then evaluated using 2,568 naturalistic driving encounters. Experimental results demonstrate that our proposed generic framework incorporated with unsupervised learning can cluster multi-trajectory data into distinct groups. These clustering results could benefit decision-making policy analysis and design for autonomous vehicles.
