基于CiteSpace的公路视线诱导设施知识图谱分析

Knowledge Graph Analysis of Highway Sightline Guidance Facilities Based on CiteSpace

摘要:

为系统梳理公路视线诱导设施领域的研究现状与发展趋势，提升其在复杂交通环境中的设计与应用水平，采用CiteSpace软件对1995—2024年间中国知网（CNKI）与Web of Science（WoS）数据库中的627篇中英文文献进行了文献计量分析。通过关键词共现挖掘高频关联词汇，运用聚类分析归纳研究主题类别，利用突现分析捕捉研究热点的动态变化，借助时间线可视化呈现研究演进脉络，进而构建该领域的知识图谱。研究结果表明，公路视线诱导设施的研究已由早期的结构功能探讨，逐步拓展至光学设计、材料优化、驾驶员行为分析及智能化应用等方面。当前研究重点聚焦于设施在复杂环境中的适应性设计及其与智能交通系统的融合。未来发展趋势将更加注重设施的精细化、多功能化与信息技术集成，以提升道路交通系统的安全性与运行效率。

Abstract:

To systematically review the research status and development trends in the field of highway sightline guidance facilities and enhance their design and application in complex traffic environments, a bibliometric analysis is conducted on 627 Chinese and English literatures in the databases of China National Knowledge Infrastructure (CNKI) and Web of Science (WoS) from 1995 to 2024 using CiteSpace software. The high-frequency related words are mined through keyword co-occurrence. The theme categories are summarized using cluster analysis. The dynamic changes of research hotspots are captured by burst analysis. And the research evolution context is presented with timeline visualization. Thereby the knowledge graph of this field is constructed. The results show that research on highway sightline guidance facilities has evolved from early exploration of structural functions and gradually expands to aspects such as optical design, material optimization, driver behavior analysis and intelligent applications. The current research focuses on the adaptive design of these facilities in complex environments and their integration with intelligent transportation systems. The future trends will emphasize the refinement, multi-functionality, and integration of information technology to enhance the safety and operational efficiency of road traffic system.
