Lane-changing (LC) behavior describes the lateral movement of the vehicle from the current-lane to the target-lane while proceeding forward. Among the many research directions, LC duration (LCD) measures the total time it takes for a vehicle to travel from the current lane to the target lane, which is an indispensable indicator to characterize the LC behavior. Although existing research has made some achievements, less attention has been paid to the research of heavy vehicles' LCD. Therefore, this paper aims to further explore the LCD between heavy vehicles and passenger cars. LC trajectories are extracted from the newly-released HighD dataset, which contains of 16.5 hours of measurement and over 11,000 vehicles. The survival function of LCD has been estimated, and the characteristic has been analyzed. Thereafter, the Accelerated Failure Time model is introduced to explore the influencing factors. Results demonstrate that the MST value of passenger cars and heavy vehicles is about 5.51s and 6.08s. The heavy vehicles would maintain a longer time-headway and distance-headway with preceding vehicle when performing LC. Nevertheless, these two factors do not significantly affect the LCD of heavy vehicles. Finally, the results and the modeling implications have been discussed. We hope this paper could contribute to our further understanding of the LC behaviors for heavy vehicles and passenger cars.

重型汽车和乘用车换道时长的探索：一种生存分析方法

变道 (LC) 行为描述了车辆在向前行驶时从当前车道到目标车道的横向移动。在众多研究方向中，LC持续时间（LCD）衡量车辆从当前车道行驶到目标车道所需的总时间，是表征LC行为不可或缺的指标。现有研究虽然取得了一些成果，但对重型车辆液晶显示器的研究关注较少。因此，本文旨在进一步探讨重型车辆和乘用车之间的液晶显示器。LC 轨迹是从新发布的 HighD 数据集中提取的，该数据集包含 16.5 小时的测量和超过 11,000 辆车。估计了LCD的生存函数，分析了其特性。此后，引入加速失效时间模型探索影响因素。结果表明，乘用车和重型车辆的 MST 值约为 5.51s 和 6.08s。重型车辆在执行LC时会与前车保持更长的车头时距和车头距。尽管如此，这两个因素对重型车辆的 LCD 没有显着影响。最后，讨论了结果和建模意义。我们希望本文能有助于我们进一步了解重型车辆和乘用车的 LC 行为。重型车辆在执行LC时会与前车保持更长的车头时距和车头距。尽管如此，这两个因素对重型车辆的 LCD 没有显着影响。最后，讨论了结果和建模意义。我们希望本文能有助于我们进一步了解重型车辆和乘用车的 LC 行为。重型车辆在执行LC时会与前车保持更长的车头时距和车头距。尽管如此，这两个因素对重型车辆的 LCD 没有显着影响。最后，讨论了结果和建模意义。我们希望本文能有助于我们进一步了解重型车辆和乘用车的 LC 行为。
