论文摘要
由于各种潜在的优势，最近已经提出了无车道车辆行动，用于连接的自动车辆（CAV）。这样的优势之一是由于无车道交通中道路宽度的增量变化导致交通流量的相应变化。基于此属性，最近引入了内部边界控制的概念，以灵活地在高速公路的两个交通方向上，以响应现行的交通状况，以在高速公路的两个交通方向上共享总道路宽度和容量。本文适当开发了基于反馈的线性季度调节器（LQI和LQ调节器），以有效解决内部边界控制问题。模拟研究涉及现实的高速公路延伸和不同的需求场景，表明所提出的简单调节剂具有强大的效率，并且像开环非线性约束最佳控制解决方案一样有效，同时规避了准确的建模和外部需求预测的需求
Lane-free vehicle movement has been recently proposed for connected automated vehicles (CAV) due to various potential advantages. One such advantage stems from the fact that incremental changes of the road width in lane-free traffic lead to corresponding incremental changes of the traffic flow capacity. Based on this property, the concept of internal boundary control was recently introduced to flexibly share the total road width and capacity among the two traffic directions of a highway in real-time, in response to the prevailing traffic conditions, so as to maximize the cross-road (both directions) infrastructure utilization. Feedback-based Linear-Quadratic regulators with or without Integral action (LQI and LQ regulators) are appropriately developed in this paper to efficiently address the internal boundary control problem. Simulation investigations, involving a realistic highway stretch and different demand scenarios, demonstrate that the proposed simple regulators are robust and similarly efficient as an open-loop nonlinear constrained optimal control solution, while circumventing the need for accurate modelling and external demand prediction
