考虑到有效运行的交通系统的目标，我们在这里提出了一种新的方法，利用连接的和部分自动化的车辆的存在来进行车道变换和匝道控制。特别是，我们假设一定百分比的车辆可以接收和执行特定的控制任务(例如，换道命令)。基于一个简单的线性时间不变(LTI)模型，设计了一种新的方法，利用线性二次积分(LQI)调节器和抗终结方案相结合，在高速公路瓶颈处稳健地最大化吞吐量。通过在一阶多车道宏观交通流模型上进行的仿真实验对该方法进行了评估，该模型也具有通行能力下降现象，从而验证了所开发方法的有效性，并突出了在交通效率方面的改善。
Considering the target of an operating effectively transportation system, we propose here a novel methodology for integrated lane-changing and ramp metering control that exploits the presence of connected and partly automated vehicles. In particular, we assume that a percentage of vehicles can receive and implement specific control tasks (e.g., lane-changing commands). A novel approach is designed to robustly maximise the throughput at motorway bottlenecks employing a Linear Quadratic Integral (LQI) regulator in combination with an anti-windup scheme, based on a simple Linear Time Invariant (LTI) model. The method is evaluated via simulation experiments, performed on a first-order, multi-lane, macroscopic traffic flow model, also featuring the capacity drop phenomenon, which allows to demonstrate the effectiveness of the developed methodology and to highlight the improvement in terms of traffic efficiency.
