Abstract:

Thanks to the development of mobile positioning technology,mobile GIS and IOT technology,the serviceability of dynamic traffic information is constantly improving.So a substantial promotion of data management efficiency is required.By means of the expansion of the concept hierarchy of ontology and its semantic characteristics,Geo-ontology was applied to manage the dynamic traffic data.In view of the theory and method of ontology,a simple applied ontology on traffic was constructed based on the traffic ontology hierarchy model.Thus an application framework of traffic information ontology was given.Ultimately,an overall discussion about the availability and the implementation of the dynamic traffic information ontology was taken at the end of this paper.With the practical data tested,the model established is contributed to solve the problem of multi-subject dynamic information integration and to enhance the level of traffic information service.

Key words: traffic information, data model, geo-ontology, traffic-ontology
