摘　　要：以车联网大数据环境下的新型交通信息服务协同体系建设为目标,在深入分析车联网和大数据的内涵和技术特征的基础上,针对交通信息服务的应用需求,基于分布移动交通信息原子服务计算平台,提出了新型交通信息服务协同体系,包括交通信息服务模型描述、基于机会通信的服务发现协议、基于语义的交通信息服务匹配算法和上下文驱动的服务动态组合4个部分,从这4个方面入手,建立了车联网大数据环境下的新型交通信息服务协同原型系统,验证了服务描述、服务发现、服务匹配服务组合技术。研究结果表明:新型交通信息服务协同体系能够很好地提高交通信息服务的智能化和个性化水平,服务质量明显提高,用户所需服务供给的针对性显著提高;该服务协同体系能为车联网用户提供更为智能和个性化的交通信息服务,有助于保障交通运输的安全和高效运营。The aim of this article is to construct a new type of traffic information service coopera- tion architecture based on vehicular network big data. Through in-depth analysis of the connota- tion and technology characteristics of vehicular network big data, a traffic information service co- operation architecture for the requirements of traffic information service was proposed. This co- operation architecture included four parts： the traffic information service model description, serv- ice discovery protocol based on opportunity communication, matching algorithm for traffic infor- mation service based on semantics and context driven dynamic service composition. This kind of new traffic information service cooperation architecture had been validated in a service cooperation prototype system from the related four aspects. The results show that the service cooperation ar-chitcture can greatly improve the traffic information servicers intelligence and individuation. The service quality is obviously improved. The ability of traffic information servicers supply is im- proved significantly. This new traffic information service cooperation architecture can supply more intelligent and personalized traffic information service for vehicular network users helps to guarantee the traffic safety and efficient operation.
