The compilation and management statuses of transportation data standards in China were analyzed. Transportation data standards were divided into 4 categories, including management standard, data definition standard, exchange standard and interface implementation standard.The standardization demands were analyzed and contrasted with the existing standards from the aspects of data producing, storage, exchange and application.Research status and deficiency of transportation data standards were discussed from management and overall planning, data definition, data storage, data exchange and decision support application.Analysis result indicates that in present standard management and overall planning, the bottom-up compilation and respective responsibility of informatization professional standard committees (IPSCs) lead to overlap of IPSCs and insufficient of overall planning research.In terms of data definition standards, the existing basic standards put too much emphasis on meeting the needs of application systems, causing the inadequacies of fundamentality of basic standards and the lack of data definition standard system.In terms of data storage, the setting of data storage standards is still blank.In terms of data exchange, the internal standards of each business system are alreadymade, but a systematic and opening mechanism for sharing and exchanging is still not established.In terms of decision support applications, decision support method for accurate data and large data is shortage.It is suggested that traffic information basic standard workshop should be set up to enhance the overall planning research and collaborate with the different IPSCs in management.In standard construction, the top-level design should be enhanced.Meanwhile, the research of transportation decision support method should be strengthened.
