摘要:

车辆跟驰行为已经被广泛研究,使用基于物理的模型,如智能驾驶员模型。这些模型成功地解释了在现实世界中观察到的交通现象,但可能无法完全捕捉驾驶的复杂认知过程。另一方面,深度学习模型已经证明了它们在捕捉观察到的交通现象方面的能力,但需要大量的驾驶数据来进行训练。本文旨在开发一系列基于神经网络的跟车模型,这些模型由基于物理的模型提供信息,这些模型利用了基于物理的模型(数据高效且可解释)和基于深度学习的模型(可推广)的优势。我们设计了基于物理学的深度学习跟车(PIDL-CF)架构,该架构使用两种流行的基于物理学的模型- IDM和OVM进行编码,在该模型上预测四种交通状况的加速度:加速、减速、巡航和紧急制动。两种类型的PIDL-CFM问题进行了研究,一个预测加速度,另一个联合预测加速度和发现模型参数。我们还证明了PIDL与下一代仿真(NGSIM)数据集的优越性能,特别是当训练数据稀疏。结果表明,由物理学提供信息的神经网络的性能优于没有物理学信息的神经网络。开发的PIDL-CF框架具有驾驶模型的系统辨识和自动驾驶车辆的驾驶控制开发的潜力。

英文摘要:

Car-following behavior has been extensively studied using physics-based models, such as the Intelligent Driver Model. These models successfully interpret traffic phenomena observed in the real-world but may not fully capture the complex cognitive process of driving. Deep learning models, on the other hand, have demonstrated their power in capturing observed traffic phenomena but require a large amount of driving data to train. This paper aims to develop a family of neural network based car-following models that are informed by physics-based models, which leverage the advantage of both physics-based (being data-efficient and interpretable) and deep learning based (being generalizable) models. We design physics-informed deep learning car-following (PIDL-CF) architectures encoded with two popular physics-based models - IDM and OVM, on which acceleration is predicted for four traffic regimes: acceleration, deceleration, cruising, and emergency braking. Two types of PIDL-CFM problems are studied, one to predict acceleration only and the other to jointly predict acceleration and discover model parameters. We also demonstrate the superior performance of PIDL with the Next Generation SIMulation (NGSIM) dataset over baselines, especially when the training data is sparse. The results demonstrate the superior performance of neural networks informed by physics over those without. The developed PIDL-CF framework holds the potential for system identification of driving models and for the development of driving-based controls for automated vehicles.
