摘要:

自动驾驶汽车(AV)预计将有利于按需移动(MoD),这要归功于它们的全球协调能力。为了促进向完全自主的稳定过渡,我们考虑了自动驾驶部署的过渡期,国防部系统运行自动驾驶车辆(AV)和人类驾驶车辆(HV)的混合车队。在这样的系统中,AV由操作者集中协调,并且HV可以策略性地响应AV的协调。我们设计计算易处理的战略,以协调国防部系统中的混合舰队。具体来说,我们使用Stackelberg框架,其中国防部运营商作为领导者和人类驾驶的车辆作为追随者的混合车队的国防部系统建模。我们开发了两个模型:1)稳态模型,用于分析问题的属性并确定规划变量(例如,补偿,价格和AV的车队规模),以及2)时变模型,以设计用于AV的实时协调算法。所提出的模型进行了验证,使用的案例研究的启发,在新加坡的国防部服务的实际操作数据。实验结果表明,该算法能显著提高系统性能。

英文摘要:

Automated vehicles (AVs) are expected to be beneficial for Mobility-on-Demand (MoD), thanks to their ability of being globally coordinated. To facilitate the steady transition towards full autonomy, we consider the transition period of AV deployment, whereby an MoD system operates a mixed fleet of automated vehicles (AVs) and human-driven vehicles (HVs). In such systems, AVs are centrally coordinated by the operator, and the HVs might strategically respond to the coordination of AVs. We devise computationally tractable strategies to coordinate mixed fleets in MoD systems. Specifically, we model an MoD system with a mixed fleet using a Stackelberg framework where the MoD operator serves as the leader and human-driven vehicles serve as the followers. We develop two models: 1) a steady-state model to analyze the properties of the problem and determine the planning variables (e.g., compensations, prices, and the fleet size of AVs), and 2) a time-varying model to design a real-time coordination algorithm for AVs. The proposed models are validated using a case study inspired by real operational data of a MoD service in Singapore. Results show that the proposed algorithms can significantly improve system performance.
