摘要

为了实现一个成功的交通框架,我们提出了一种结合变道和匝道计量控制的新方法,其中包括部分连接和自动驾驶车辆的存在。最优控制器的主要测试趋向于协调坡道计量流饱和边界。具体来说,期望某一级别的车辆获得并执行明确的控制任务(例如,变道控制信号)。利用线性二次积分(LQI)控制器和针对LTI模型的防停机计划,介绍了另一种有效扩展高速公路瓶颈吞吐量的方法。在评价方面,将该方法应用于仿真模型,采用宏观交通模型,即一阶多车道流模型。此外,还执行了容量下降特性,以解决所创建的方法处理所演示的效果,与高峰时段交通效率的提高相同。

Flow metering and lane-changing optimal control with ramp-metering saturation
To accomplish a successful transportation frame-work, we present a new approach to incorporate lane-changing and ramp-metering control, which includes the presence of partially connected and autonomous vehicles. The primary test tended to is coordinating the ramp-metering flow saturation boundaries in the optimal controller. Specifically, a level of vehicles is expected to get and carry out explicit control assignments (e.g., lane-changing control signals). Utilizing a Linear Quadratic Integral (LQI) controller and an anti-windup plan in view of a LTI model, another methodology is introduced for powerfully expanding the throughput at motorway bottlenecks. In terms of assessment, the methodology is implemented on the simulated model, uses a macroscopic traffic model which is a first-order flow model including multi-lane. The capacity drop peculiarity is additionally executed, that addresses the effect of the created method to deal with be demonstrated, same as the improvements in rush hour traffic effectiveness.
