Unlike data in other fields, traffic data cannot be analyzed and interpreted only with basic metadata. Therefore, it is essential to understand the linkage and relationship between data. Recently, the demand for data on the transportation sector is increasing. In addition, data types are also diversifying accordingly, so both users and managers need to understand the data. Therefore, in this study, an empirical study was conducted on a DCAT-based traffic data catalog using traffic data that can be collected in Sejong City so that it can be understood and applied from the perspective of managers and users. To this end, a DCAT-based traffic data catalog was defined based on the traffic data that can be collected in Sejong City, and using this, a service screen was conceived and developed from the user’s perspective.If it is possible to collect C-IPTS data in the future, it will be possible to design and develop various service screens for users through this, and more accurate data analysis will be possible. In addition, although it has been proposed to provide information according to vehicle classification in the present, if we promote the development of service screens in various aspects such as by route, region, and road in the future, and further provide statistics and aggregate information, it is possible to improve transportation services of public officials related to Sejong City.
