本研究的目的是定义一个操作概念，涉及连接自动驾驶汽车（CAV）的高速公路管理车道上的操作。尽管在未来十年中CAV的市场渗透率预计较低，但使用管理车道设施有可能支持实现其本质上的增加的流动性效益。建议的CAV操作涉及装备的飞行器排，由集成的CAV应用程序管理，包括合作自适应巡航控制（CACC），合作合并，和速度协调。本研究提出一个整合CAV应用程式的演算法。通过微观模拟，重点考察了在不同渗透率下，CACC、CACC+合作兼并以及加入速度协调的有效性。仿真结果表明，捆绑应用程序的有效性，以提高系统的吞吐量和减少延迟，即使在低CAV的穿透率。在中高渗透率下，速度协调对延迟减少的影响最大，即使在低渗透率下也有一定的好处。研究结论为交通管理中心今后实施CAV交通控制提供了可操作性的指导。
The purpose of this study is to define an operational concept involving connected automated vehicle (CAV) operation on freeway managed lanes. Despite the low projected market penetration of CAVs during the next decade, the use of managed lane facilities has the potential to support the realization of increased mobility benefits by their very nature. The proposed CAV operation involves platoons of equipped vehicles governed by integrated CAV applications, including cooperative adaptive cruise control (CACC), cooperative merge, and speed harmonization. This study proposes an algorithm for integrating CAV applications. Through microscopic simulation, the study particularly examines the effectiveness of CACC, CACC plus cooperative merge, and the addition of speed harmonization under different penetration rates. Simulation results show the effectiveness of the bundled application to enhance system throughput and reduce delay, even with low CAV penetration rates. The speed harmonization shows the greatest effects on delay reduction at medium-to-high penetration rates and some benefits even at low penetration rates. The conclusions provide operational insights and guidance for traffic management centers to implement CAV-based traffic control in the future.
