1Institute of Transport Studies, Monash University, Clayton, VIC, 3800, Australia.
This study visualizes road safety research using bibliometric analysis. "Crash frequency modeling analysis" is the core topic, with spatial statistics as a key emerging area.
Area of Science:
- Road safety research
- Scientometric analysis
- Knowledge domain mapping
Background:
- Visualizing knowledge domains aids in understanding academic communities and research development.
- Bibliometric analysis offers a quantitative approach to studying scientific disciplines.
Purpose of the Study:
- To visually map the field of road safety research.
- To identify core authors, classic documents, and citation networks.
- To analyze the structure and development of road safety studies.
Main Methods:
- Utilized bibliometric tools VOSviewer and CitNetExplorer.
- Analyzed articles from Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI).
- Created maps of author co-citation, document co-citation, and citation networks.
Main Results:
- Road safety studies clustered into four main groups: driving psychology/behavior effects, crash causation/severity analysis, injury epidemiology/prevention, and driver risk factors/performance.
- "Crash frequency modeling analysis" identified as the core research topic.
- Spatial statistical analysis emerged as a frontier research area.
Conclusions:
- Bibliometric mapping effectively reveals the structure and dynamics of road safety research.
- Crash frequency modeling is central to the field, with spatial statistics offering new avenues for investigation.
