论文摘要
在本文中，我们解决了在无信号十字路口协调连接和自动车辆的排的问题。我们提出了一个分散的两级最佳框架，以协调排的目标，以最大程度地减少跨越交叉路口的每个排的旅行延迟和燃油消耗。在上层中，每个排都得出了进入交叉点的最佳时间表。在低水平中，排出了其最佳控制输入（加速/减速），以获得上层级别的最佳时间表。我们验证了拟议框架在模拟中的有效性，与基线场景相比，在交叉路口固定的时间交通信号相比，旅行延迟和燃油消耗的有效性。
In this paper, we address the problem of coordinating platoons of connected and automated vehicles at signal-free intersections. We present a decentralized, two-level optimal framework to coordinate the platoons with the objective to minimize travel delay and fuel consumption of every platoon crossing the intersection. In the upper-level, each platoon derives an optimal schedule to enter the intersection. In the low-level, the platoons derive their optimal control input (acceleration/deceleration) for the optimal schedule derived in the upper-level. We validate the effectiveness of the proposed framework in simulation and show significant improvements both in travel delay and fuel consumption compared to the baseline scenario with fixed time traffic signals at the intersection.
