| Abstract: | To adapt the development of diversified business in integrative transportation network and realize the compatibility, standardization and adaptability of traffic information transmission, Web, CORBA and QT cross-platform technologies in heterogeneous information system and H.264 video trans-coding principle were studied, the basic transmission requirements on data and images of ITS were analyzed, a traffic information surveillance technology was proposed, and the Web browser interface of scalable SVG map based on B/S mode and the ViewBox window based on C/S mode and H.264 video trans-coding technology were taken as its base. Application result shows that the new technologies can satisfy the requirements of wide area and real time of ITS, and can improve the cross-platform transmission quality of ITS images and system robustness. 8 figs, 16 refs. |
