Abstract
As the demand for high-speed railway, light railway, and metropolitan railway is increasing, the demand for safe and comfortable railways is increasing. The evaluation technology for a railway system manufactured according to this trend is becoming more important. This study examined the domestic and foreign technology trends through patent analysis of the railway test technology. To accomplish this, the patents filed in Korea, Europe, and the United States since 1990 were analyzed using Thomson Innovation DB. First, the technology was classified as a component test, combined test, and on-line test. Through patent analysis, the technology trends in the railway test technology and how the technological progress has been made from the past to the present were reviewed. In addition, through an analysis of the country and main applicant, this study examined the countries and applicants that are actively developing technologies. In addition, the countries that have secured technology related to the test technology were studied through an analysis of the market security index and the influence index. Through this analysis, this study analyzed the trend of the test technology in the railway area.
