“互联网 +”智能交通有利于促进交通设施和运营的数据信息资源互通共享，实现运输组织的方式优化和价值创造，进而全面提升公众交通出行的获得感。为积极应对“互联网 +”智能交通的发展新需求，本文梳理了领域发展现状与面临问题，总结了与多个行业和领域的融合发展趋势，阐述了“互联网 +”智能交通的体系架构。研究提出，依托北斗卫星导航系统、第五代移动通信（5G）等我国具有国际竞争力的新型关键基础设施，坚持交通出行即服务理念，打造泛在、随动、无缝、可信、智能的出行链；重点突破或加强“北斗 + 5G”等自主关键技术的创新融合、具有智能精准控制能力的车联网和智能网联汽车、车联网产业生态、政策保障力度等，更好地促进我国“互联网 +”智能交通的健康发展。

Internet Plus Intelligent Transportation can promote data and information sharing among traffic facilities during traffic operation. It can also optimize the operation modes of transportation organizations, increase economic and social values, and comprehensively satisfy people’s mobility needs. To actively meet the new development needs, this study clarifies the current development and problems of the Internet Plus Intelligent Transportation model, summarizes its integration trend with other industries and fields, and expounds the architecture of Internet Plus Intelligent Transportation. It is proposed that a travel chain should be created that is ubiquitous, flexible, seamless, trusted, and intelligent, based on the intelligent Transportation as a Service concept (iTaaS) and new critical infrastructures in China with international competitiveness such as the BeiDou satellite navigation system and 5G technology. Moreover, it is also necessary to strengthen the independent innovation and integration of key technologies, establish an Internet of Vehicles with intelligent and precise control while developing intelligent connected vehicles, cultivate an industrial ecology for the Internet of Vehicles, and strengthen policy guarantees.
