Mapping knowledge domain (MKD) is an important application of visualization technology in Bibliometrics, which has been extensively applied in psychology, medicine, and information science. In this paper we conduct a systematic analysis of the development trend on road safety studies based on the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI) articles published between 2000 and 2018 using the MKD software tools VOSviewer and Sci2 Tool. Based on our analysis, we first present the annual numbers of articles, origin countries, main research organizations and groups as well as the source journals on road safety studies. We then report the collaborations among the main research organizations and groups using co-authorship analysis. Furthermore, we adopt the document co-citation analysis, keywords co-occurrence analysis, and burst detection analysis to visually explore the knowledge bases, topic distribution, research fronts and research trends on road safety studies. The proposed approach based on the visualized analysis of MKD can be used to establish a reference information and research basis for the application and development of methods in the domain of road safety studies. In particular, our results show that the knowledge bases (classical documents) of road safety studies in the last two decades have focused on five major areas of "Crash Frequency Data Analysis", "Driver Behavior Questionnaire", "Safety in Numbers for Walkers and Bicyclists", "Road Traffic Injury and Prevention", and "Driving Speed and Road Crashes". Among the research topics, the five dominant clusters are "Causation and Injury Severity Analysis of Road Accidents", "Epidemiologic Study and Prevention of Road Traffic Injury", "Intelligent Transportation System and Active Safety", "Young drivers' driving behavior and psychology", and "Older drivers' psychological and physiological characteristics". Finally, the burst keywords in research trends include Cycling, Intelligent Transportation Systems, and Distraction.
知识图谱是文献计量学可视化技术的重要应用，已广泛应用于心理学、医学和信息科学等领域。本文采用知识图谱软件工具 Vosviewer 和 Sci2Tool，基于 2000 年至 2018 年科学引文索引扩展版（SCIE）和社会科学引文索引（SSCI）收录的文献，对道路安全研究的发展趋势进行了系统分析。首先，本文展示了道路安全研究领域的文献年度数量、来源国家、主要研究机构和团体以及源期刊。然后，通过合著分析报告了主要研究机构和团体之间的合作情况。此外，采用文献共被引分析、关键词共现分析和突现检测分析，直观地探索了道路安全研究的知识基础、主题分布、研究前沿和研究趋势。基于知识图谱可视化分析的方法，为道路安全研究领域的方法应用和发展提供了参考信息和研究基础。特别是，本文的研究结果表明，过去二十年道路安全研究的知识基础（经典文献）主要集中在“碰撞频率数据分析”、“驾驶员行为问卷”、“行人和自行车安全数量”、“道路交通伤害与预防”和“驾驶速度与道路碰撞”等五个主要领域。在研究主题方面，五个主要聚类为“道路事故的因果关系和伤害严重程度分析”、“道路交通事故的流行病学研究与预防”、“智能交通系统与主动安全”、“年轻驾驶员的驾驶行为和心理”和“老年驾驶员的心理和生理特征”。最后，研究趋势中的突现关键词包括 Cycling、Intelligent Transportation Systems 和 Distraction。
