As the most important technology in the development of semantic web, ontology can help computers not only to understand each other but also to share information on the web. Therefore more and more researchers begin to realize that how important to have their domain ontology supporting for reason within the domain knowledge. In this paper, urban public transport ontology is proposed with the key concepts and relations in transportation system, and established by Protégé and Jena software, to help solving some problems existing in transportation system, such as differentiating the same station names and querying with more semantic information. Also, we adopt an improved public transport transfer query algorithm which considers both road conditions and costumer's various needs, including transfer times, walking distance, and price etc. Finally, based on the proposed ontology and the improved query algorithm, we implement a public transport query system, and also do our preliminary experimental verification with six roads, 14 stations and 5 offices. And the experimental results show that our query system has good performance.
