Pedestrian deaths constitute 23% of road traffic deaths globally. Although several research papers have contributed to pedestrian safety analysis, they did not provide a comprehensive overview of the progress in the research domain and publication trends. This makes it difficult to identify trends and insights into the pedestrian research domain in light of the voluminous number of papers. This study fills this gap with a scientometric analysis of research on pedestrian safety analysis indexed in the Web of Science. The scope covers 2594 papers published between 2010 and 2021 in English. This study analyzed the annual publications and citation trends, top ten most cited papers, influential papers in their first three years after publication, contributing authors, funding agencies, and contributing journals. The regional gaps between the proportion of pedestrian deaths and research were also analyzed. The results showed low research productivity from low and middle-income countries although they have a high incidence of pedestrian deaths. Subsequently, the main keyword clusters or frontier topics were identified and topic analysis was employed to identify the evolution of studies. Four keyword clusters were identified, i.e., "vehicle-to-pedestrian crash and injury severity analysis", "pedestrian movement and decision simulation experiments", "improving the vehicle system towards reducing body region impact injuries", "pedestrian behavior in crosswalks and signalized intersections". This study contributes an integrated knowledge map of pedestrian safety analysis, publication trends, the evolution of studies, and under-researched topics to guide future research work in pedestrian safety analysis.
行人死亡占全球道路交通死亡人数的 23%。尽管有几篇研究论文对行人安全分析做出了贡献，但它们没有全面概述研究领域的进展和出版趋势。考虑到大量的论文数量，这使得难以确定趋势和洞察行人研究领域。本研究通过对 Web of Science 中索引的行人安全分析研究进行科学计量分析，填补了这一空白。范围涵盖 2010 年至 2021 年间以英文发表的 2594 篇论文。本研究分析了年度出版物和引文趋势、被引频次最高的 10 篇论文、发表后前三年的有影响力的论文、主要作者、资助机构和主要期刊。还分析了行人死亡比例与研究之间的区域差距。结果表明，尽管低收入和中等收入国家行人死亡发生率较高，但研究生产力较低。随后，确定了主要的关键词聚类或前沿主题，并进行了主题分析以确定研究的演变。确定了四个关键词聚类，即“车-行人碰撞和伤害严重程度分析”、“行人运动和决策模拟实验”、“改进车辆系统以减少身体区域撞击伤”、“行人在横道和信号交叉口的行为”。本研究为行人安全分析提供了综合的知识图谱，包括出版趋势、研究演变和研究不足的主题，以指导行人安全分析的未来研究工作。
