Study on architecture of seamless transportation information grid
无缝运输信息网格的体系结构研究

Because the heterogeneous information is relatively loose and independent in seamless transportation, data grid is adopted to manage the distributed heterogeneous information and realize resources share and information integration. The paper presents a architecture of seamless transportation information grid(STIG),the architecture integrates Information integration, semantic query, transportation planning, etc key technologies. At last, take combined rail and sea transport for example, the process of multimodal transportation based on STIG was described.
