论文摘要
连接和自动驾驶汽车（CAVS）的排队具有巨大的吞吐量改善潜力。但是，骑士与非车辆之间的相互作用可能会限制由于排成线而实际上可实现的改进。为了更好地理解和解决此限制，我们引入了一种新的混合自治流量流动模型，并使用此模型来分析和设计排的协调策略。我们提出了串联链接流体模型，该模型考虑了随机到达与非cavs共享高速公路容量的排名。我们通过分析基本的M/D/1排队过程并为流体模型建立寄养 - lyapunov漂移条件，从而得出了流体模型稳定性的可验证条件。这些稳定条件能够在各种情况下对公路吞吐量进行定量分析。该模型可用于设计最大化吞吐量并最大程度减少延迟的排同步协调策略。这种协调策略在流体模型中是最佳的，并且实际上是相关的。我们还使用标准宏观传播模型，CTM）和微观（城市迁移率，SUMO）模拟模型来验证结果。
Platooning of connected and autonomous vehicles (CAVs) has a significant potential for throughput improvement. However, the interaction between CAVs and non-CAVs may limit the practically attainable improvement due to platooning. To better understand and address this limitation, we introduce a new fluid model of mixed-autonomy traffic flow and use this model to analyze and design platoon coordination strategies. We propose tandem-link fluid model that considers randomly arriving platoons sharing highway capacity with non-CAVs. We derive verifiable conditions for stability of the fluid model by analyzing an underlying M/D/1 queuing process and establishing a Foster-Lyapunov drift condition for the fluid model. These stability conditions enable a quantitative analysis of highway throughput under various scenarios. The model is useful for designing platoon coordination strategies that maximize throughput and minimize delay. Such coordination strategies are provably optimal in the fluid model and are practically relevant. We also validate our results using standard macroscopic (cell transmission model, CTM) and microscopic (Simulation for Urban Mobility, SUMO) simulation models.
