摘　　要：在分析本体技术和交通信息特点的基础上,针对交通概念描述的特殊要求,提出了时空模糊本体的概念,以描述交通领域概念,并利用时空模糊本体进行交通领域知识建模。We propose the concept of spatio-temporal fuzzy ontology （STFO）, focusing on the description of transportation information. The STFO architecture contains basic struc- ture, concept top-level ontology, property top-level ontology, and relationship top-level ontology, The STFO which provides the description of spatial relationship, state-process- change, fuzzy value of property, and fuzzy relationship, is more suitable to describe the transportation information. In conclusion, the transportation knowledge modeling based on STFO establishes an unified and canonical knowledge architecture, which improves the abilities of the sharing and reuse of transportation information.
