Leading Cruise Control in Mixed Traffic Flow

Jiawei Wang, Yang Zheng, Chaoyi Chen, Qing Xu, Keqiang Li

摘要:

车对车(V2V)通信在改善交通系统性能方面具有巨大潜力。现有的联网自动驾驶汽车(CAV)的研究大多集中在对下游交通状况的适应上,忽略了CAV的行为对上游交通流的影响。在本文中,我们引入了领先巡航控制(LCC)的概念,保留了基本的汽车跟随操作,并明确考虑了CAV的行动对后面的车辆的影响。我们首先提出了一个详细的建模过程LCC。然后,严格的可控性分析验证了利用CAV作为领导者的可行性,积极引导其后续车辆的运动。此外,在充分利用V2V连接性的情况下,推导了LCC的头到尾传递函数。数值研究证实了LCC在增强CAV抑制交通不稳定性和平滑交通流能力方面的潜力。

英文摘要:

Vehicle-to-vehicle (V2V) communications have a great potential to improve traffic system performance. Most existing work of connected and autonomous vehicles (CAVs) focused on adaptation to downstream traffic conditions, neglecting the impact of CAVs' behaviors on upstream traffic flow. In this paper, we introduce a notion of Leading Cruise Control (LCC) that retains the basic car-following operation and explicitly considers the influence of the CAV's actions on the vehicles behind. We first present a detailed modeling process for LCC. Then, rigorous controllability analysis verifies the feasibility of exploiting the CAV as a leader to actively lead the motion of its following vehicles. Besides, the head-to-tail transfer function is derived for LCC under adequate employment of V2V connectivity. Numerical studies confirm the potential of LCC to strengthen the capability of CAVs in suppressing traffic instabilities and smoothing traffic flow.
