General users are actively seeking web-based transportation information and are trying to apply it into their lives. Now the implementation of user-centered transportation information services are becoming the essential activity for pertinent companies or public institutions. In this paper the author tried to measure the quality of web sites featuring transportation information using the robust measurement tool called WebQual. In addition, the author investigated the relationship between the components of WebQual (usability, information quality, and interactivity) and satisfaction/intention to revisit. According to the results, WebQual had the effectiveness of confirming the service quality for the web sites of transportation information.

Volume in data storage is growing more than ever before. This phenomenon is caused by the participation of governments and firms as well as general users. As for big data, governments and public agencies are likely to play important roles in applications since they can access and operate personal data for public purposes. In this study, the author examined the status and countermeasure of big data from different countries and drew some common grounds. The suggestions are as follows. First of all, securing manpower and technology have to take precedence. In addition, share and development between the government and the private sector are required. And organizations should come up with long-term strategies along with the development of data loading and analysis. In conclusion, the author propose the recognition of the importance of data management, privacy protection and the expansion of field application possibilities for political usage of big data.
