Reasonable integration of transportation information resources can effectively improve the performance of ITS.In order to achieve the integration goal of ITS,this paper proposed a novel SUMO-based four-layer ITS decision ontology by using grid as resource storage and cooperation platform,and utilizing ontology as resource expression base.Based on the model,this paper discussed a mechanism of heterogeneous information access and demonstrated it by a traffic accident scenario.The result shows that this model availably integrates the heterogeneous resources and different domain-ontology by mapping their semantic to SUMO and promotes the decision support and open collaboration capacities of ITS.
