Abstract:With the development of intelligent transportation technology, the increasing traffic data volume has reached TB or even PB level. The intelligent transportation field has begun to use big data technology to analyze deeply the massive traffic data, to build a comprehensive intelligent traffic information Service platform. In this paper, an intelligent information service platform based on traffic big data is proposed. The paper mainly analyzes this platform from the overall architecture, application architecture and data center design of the system. Through the test, the platform can meet the early needs of the users. The platform-based hierarchy and sub-module design can be a good response to the user needs change later on.
