| 摘要: |
| 为了探索协同自适应巡航控制(cooperative adaptive cruise control, CACC)车辆对交通系统的潜在影响，分析了CACC车辆市场普及过程中存在的CACC车辆、自适应巡航控制(adaptive cruise control, ACC)车辆与人工驾驶车辆混合交通流驾驶舒适性.应用加州伯克利PATH实车验证的ACC模型和CACC模型进行数值仿真实验，采用国际ISO-2631-1标准评价混合交通流舒适性，并对ACC和CACC期望车间时距进行参数敏感性分析.最后，从交通流稳定性的角度，对舒适性仿真结果进行了讨论.结果表明：随着CACC市场率的增加，舒适性呈现先恶化、再逐渐提升的趋势.较大的ACC车间时距有利于抑制舒适性的恶化程度，CACC车辆对舒适性的提升作用不受其车间时距取值的影响.混合交通流稳定性定性地决定了舒适性的变化趋势，人工车辆安装车车通信设备，有助于舒适性的逐渐提升.

| Abstract: |
| In order to explore the potential impact of cooperative adaptive cruise control (CACC) vehicles on traffic systems, driving comfort is analyzed under different CACC penetrations where manual vehicles, CACC vehicles, and adaptive cruise control (ACC) vehicles are mixed in the process of CACC gradually increasing on roads. The ACC and CACC models validated by PATH program were employed in numerical simulations. Driving comfort of the mixed traffic flow was measured using the international organization for standardization(ISO) 2631-1. Parametric sensitivity analysis on the desired time-gap of ACC and CACC was also conducted. Finally, simulation results were discussed from the perspective of traffic flow stability. It is found that comfort first worsens then upgrades with the increase of CACC penetration. Larger ACC time-gap is apt to restrict the comfort deterioration, while various values of CACC time-gap have little effect on improving the driving comfort. The results indicate that the trend of mixed traffic flow stability affects comfort qualitatively. Vehicle-to-vehicle communication equipment of manual vehicles will benefit the gradual increase of the comfort.
