Study on NTCIP-Based Architecture of Data Center for Transportation Information System in China

Data center, which is the basis for the development of transportation information, has the basic function of data storage, processing, data exchange and information sharing. In China, it is a preliminary stage of the design and construction for data center. Difficulties like effective data sharing and executive information service are still exist. In this paper, according to the transmission of data sharing and system architecture design of National Transportation Communications for ITS Protocol (NTCIP) in U.S., the mapping relation between NTCIP and data center architecture is analyzed. The NTCIP-based architecture of data center in transportation information system on freeway is proposed, combined with the information needs of the freeway in Jiangsu Province, China. This study can be used to provide a reference for the data center construction.
