Cooperative Adaptive Cruise Control (CACC) has been regarded as the most promising technology that can be carried out in field earliest under partially connected and automated environment, and is one of the few Connected and Automated Vehicle (CAV) applications closest to its final shape. Therefore, validation of CACC running in real traffic is in urgent need. To support the validation, simulation plays a key role. This paper proposes a next-generation simulation platform for CACC evaluation and validation. It is able to not only validate the performance of a CACC platoon by itself, but also evaluate its performance when being released into the traffic. In addition, it can also quantify the impact of CACC vehicles on transportation systems. The proposed platform is generic in terms of CACC control system, background traffic condition, road geometry, and traffic control scheme. Furthermore, it is capable of capturing the dynamics of platoon formation and disengagement when CACC equipped vehicles are mixed up with human-driven vehicles. The proposed platform is validated by comparing against actual field data and previously published theoretical studies. The results confirm the credibility of the proposed platform in terms of: i) CACC control system embedded; ii) CAV and Human-driven Vehicle (HV) mixed traffic simulation; iii) managed lane simulation. It is also revealed that current CACC technology without upgrade may be a safety hazard and permitting CACC only on a dedicated CACC lane might be a good first step for CACC commercialization at this moment.

用于部分连接和自动化环境下的协同自适应巡航控制的通用仿真平台

协作式自适应巡航控制(CACC)被认为是最早可以在部分连接和自动化环境下现场进行的最有前途的技术,并且是最接近其最终形状的为数不多的连接和自动化车辆(CAV)应用之一。因此,迫切需要验证在实际流量中运行的CACC。为了支持验证,仿真起着关键作用。本文提出了用于CACC评估和验证的下一代仿真平台。它不仅能够单独验证CACC排的性能,还可以在将其发布到流量中时评估其性能。此外,它还可以量化CACC车辆对运输系统的影响。所建议的平台在CACC控制系统,背景交通状况,道路几何形状和交通控制方案。此外,当配备CACC的车辆与人力驱动的车辆混合使用时,它能够捕获排形成和脱离的动力。通过与实际现场数据和先前发表的理论研究进行比较,验证了所提出的平台。结果在以下方面证实了所提出平台的可靠性:i)嵌入式CACC控制系统;ii)CAV和人力车(HV)混合交通仿真;iii)管理车道模拟。还显示出,当前的CACC技术未经升级可能会带来安全隐患,而此时仅允许在专用CACC车道上使用CACC可能是CACC商业化的良好第一步。当配备CACC的车辆与人为驾驶的车辆混合使用时,它能够捕获排形成和脱离的动力。通过与实际现场数据和先前发表的理论研究进行比较,验证了所提出的平台。结果在以下方面证实了所提出平台的可靠性:i)嵌入式CACC控制系统;ii)CAV和人力车(HV)混合交通仿真;iii)管理车道模拟。还显示出,当前的CACC技术未经升级可能会带来安全隐患,而此时仅允许在专用CACC车道上使用CACC可能是CACC商业化的良好第一步。当配备CACC的车辆与人为驾驶的车辆混合使用时,它能够捕获排形成和脱离的动力。通过与实际现场数据和先前发表的理论研究进行比较,验证了所提出的平台。结果在以下方面证实了所提出平台的可靠性:i)嵌入式CACC控制系统;ii)CAV和人力车(HV)混合交通仿真;iii)管理车道模拟。还显示出,当前的CACC技术未经升级可能会带来安全隐患,而此时仅允许在专用CACC车道上使用CACC可能是CACC商业化的良好第一步。结果在以下方面证实了所提出平台的可靠性:i)嵌入式CACC控制系统;ii)CAV和人力车(HV)混合交通仿真;iii)管理车道模拟。还显示出,当前的CACC技术未经升级可能会带来安全隐患,而此时仅允许在专用CACC车道上使用CACC可能是CACC商业化的良好第一步。结果在以下方面证实了所提出平台的可靠性:i)嵌入式CACC控制系统;ii)CAV和人力车(HV)混合交通仿真;iii)管理车道模拟。还显示出,当前的CACC技术未经升级可能会带来安全隐患,而此时仅允许在专用CACC车道上使用CACC可能是CACC商业化的良好第一步。
