[Abstract]:Traffic information service system, as an important application of intelligent transportation, has made important contributions to alleviate traffic congestion, improve traffic quality and improve traffic service level. However, with the rapid development of economy and society, The existing traffic information service mechanism can not meet the demand of the public for the traffic information service. There are some problems such as the weak comprehensive processing ability of traffic information, the low level of intelligent service, the single mode of traffic information service and so on. The research and application of vehicle networking technology provide a new way of thinking for the development of traffic information service. The vehicle networking environment can create data conditions and basic platform for improving the quality of traffic information service. Therefore, the construction of a new traffic information service system under the vehicle networking environment has become one of the current research hotspots. Based on the above background, the paper aims to build a new traffic information service collaborative system under the vehicle networking environment. The key technologies of traffic information service cooperation under the environment of vehicle networking are studied. Firstly, based on the in-depth analysis of the technical characteristics of vehicle networking, the paper aims at the application needs of traffic information service. A new traffic information service collaborative system is proposed, which includes three parts: traffic information service model description, service discovery protocol based on opportunity communication, semantic traffic information service matching and service dynamic composition. On the basis of studying the syntax and semantic expression technology of Web service, the description method of traffic information service is analyzed, and OWL-S language modeling is proposed to realize the semantic description of traffic information service. A description model of traffic information service based on OWL-S is constructed, and then the key content of traffic information service discovery is analyzed on the basis of deeply analyzing the technology of service discovery in Web environment. The overall design of the traffic information service discovery protocol is completed, and the process of service request data distribution under the environment of vehicle network is studied, which is to establish the opportunity route to realize the data exchange between the service requestor and the service provider. Based on the research of service composition method and the characteristics of traffic information service composition, a framework of traffic information service composition based on semantic matching and workflow technology is constructed. Under this framework, the workflow of traffic information service composition and the construction method of service composition template are studied. In this paper, the cooperative system of traffic information service under the environment of vehicle networking can effectively improve the intelligence and individuation level of the traffic information service, which is based on the combination and decision method of atomic service and the execution control method of traffic information service. Enhancing the comprehensive processing ability of the transportation information service system is helpful to improve the service quality of the traffic information service system and ensure the safe and efficient operation of the transportation.
