摘　　要：为推进高速公路的智慧化建设,提升人机共驾的有效性和安全性,提出了一种高速公路人机共驾接管反应时间估计方法。以高速公路封闭道路直线段为驾驶模拟试验场景,选取驾驶行为特征变量,基于随机森林法对接管反应时间进行估计。研究结果表明:所提出模型的平均绝对百分比误差在13.56%以内,与其他回归模型相比,该模型的误差波动幅度和离散程度均处于较优水平;对特征变量的重要性进行排序后发现,接管反应时间预算对接管反应时间预测模型的影响最大,其次为驾驶员熟练程度和周围有无车辆。研究成果可为智慧高速公路的发展和驾驶控制权接管策略的评价、设计和改进提供参考。To promote the construction of freeway intelligence and improve the effectiveness and safety of human-machine co-driving,this study proposed an estimating method for the take-over reaction time of human-machine co-driving on freeways.A straight section of a closed freeway was used as the driving simulation scenario,and feature variables of the driving behavior were selected to estimate the take-over reaction time with the random forest method.The results show that the mean absolute percentage error of the proposed model is controlled within 13.56%,and its error fluctuation magnitude and dispersion degree are at better levels than those of other regression models.The importance of the feature variables was ranked,and it is found that the take-over reaction time budget has the greatest influence on the take-over reaction time prediction model,followed by driver proficiency and surrounding vehicle conditions.This research provides a reference for the development of smart freeways and the evaluation,design,and improvement of driving control take-over strategies.
