Research on public opinion related to infrastructure projects has been done in a wide range of disciplines such as civil engineering, architecture, economics, sociology and psychology. While it is important to grasp the transition and trend of these research in a bird's eye view, it is not easy to do so because the research theme is wide and the number of research papers is enormous. Therefore, in this study, a systematic method was developed and applied to retrieve academic journals by keyword group, extract and classify papers, and reveal evolution research fields and papers by systematically retracing cited documents of classified papers. As a result, 52 journals were collected for research papers from 2003 to 2018 and analyzed spreads and trends of fields and papers such as project evaluation.
