摘　　要：为了明确驾驶人换道行为在道路交通安全领域的研究现状,综述了换道模型、换道行为特征、换道辅助预警以及自主换道系统等方面的研究进展。将换道模型按照换道动机与换道决策2个维度展开论述,针对换道行为特征归纳了驾驶人换道过程中的眼部及头部运动特性,分析了车道变换时自车及周围车辆的运动状态,总结了国内外学者在换道辅助预警系统、自主换道系统的先进成果。对文献的梳理和分析结果表明:首先,由数据驱动的智能换道模型在保证时效性的基础上,相比于传统换道模型在预测精度方面得到了显著提升;其次,在换道过程中驾驶人注视兴趣区域的划分为视觉运动规律的探索提供了基础,而头眼协同运动分析则可更加全面阐述换道行为特征,从换道意图识别到换道行为预测,均为换道辅助预警系统提供了潜在解决方案,但由于意图撤销现象的存在,需要进一步甄别各类方法的适用性;最后,有必要结合车路协同技术与车联网技术的发展,使车辆的自动换道朝着全局最优化的协同换道方向推演。研究成果将为驾驶人换道行为的基础理论研究提供参考和借鉴,从而有助于道路交通安全水平的进一步提升。As a key part of building“Transportation Powerhouse”,road traffic safety is the lifeline and eternal theme of the transportation system.Research on driving operations such as car-following and lane changing is helpful to make up for the weakness in the human-vehicle-road system and effectively improve the level of road traffic safety.Compared with the simple car-following,lane changing is an unstable,difficult and high-risk driving operation that occurs in a short time.In order to reveal the factors affecting lane changing safety and explore scientific and effective lane changing warning methods,domestic and foreign scholars have carried out various studies,achieved a lot of valuable academic achievements,and provided important theoretical basis and data support for the performance improvement and optimization of various lane changing auxiliary systems.Therefore,this paper selects 7720 domestic and foreign literatures published from 2001 to 2021,uses the knowledge graph to sort out and summarize the research trends and hotspots of lane changing operations.Firstly,the lane changing model can be discussed from two different dimensions:lane changing motivation and lane changing decisions.From the perspective of lane changing motivation,the model can be divided into free lane changing model,compulsory lane changing model and comprehensive lane changing model.From the perspective of lane changing decisions,the model can be divided into feasibility model,probability model and data-driven model.Secondly,according to the characteristics of lane changing operations,eye features such as the fixation point,the search route and the fixation area of the driver in the process of lane changing and head movement characteristics based on head-eye coordination movement are summarized,the influencing factors of switching rate of turn signals and wheel-steering operation are discussed,and the influences of the motion state of the car and the surrounding vehicles during lane changing are analyzed.Then,the structure and limitation
