The knowledge map of public safety and health

With the aim of drawing the knowledge map and understanding the research hotspot on public safety and health, the articles published from 2000 to 2014 have been searched with the keyword “public safety and health” based on the Web of Science database. The knowledge map of public safety and health was drawn by utilizing the CiteSpace software. Active countries/regions, institutions and research hotspots of public safety and health have been reached. The result shows that the United States and Europe are the most active areas of public safety and health studies; Harvard is on the top of research agencies in number of articles. From the subject, it is the science and technology - other subjects and the interdisciplinary science the hot subjects since 2012. From the perspective of the key words, smoking, information, experiment, physicians, cost-effectiveness have the highest centrality; from the point of article co-citation analysis, public health, public injury/prevention and the establishment of a comprehensive, systematic, quantitative and qualitative combining research method are the hotspots of research in the field of public safety and health.
