Abstract: Transportation integration can promote the efficient flow and integration of production factors， effectively promote the integrated development of regional economy and society and the smooth realization of economic internal circulation. It is found that the urban agglomeration in the middle reaches of the Yangtze River has made great progress in transportation integration. It has not only established a complete comprehensive transportation network composed of railway， highway， subway， aviation， water transportation and other transportation modes， but also realized informatization and intelligence in traffic management and service to a certain extent. However， there are still some difficulties and problems in the construction of transportation integration of urban agglomeration in the middle reaches of the Yangtze River， such as low cooperation between the government and the market， lack of unified cross regional overall planning and coordination mechanism， low interconnection efficiency of various transportation modes， backward intelligent transportation construction and so on. We can break down administrative barriers and establish an integrated management and coordination mechanism by improving the enthusiasm of government integration and market participation， develop multimodal transport， promote interconnection and enhance the informatization and intelligent construction of traffic management and services to further promote the construction of traffic integration of urban agglomeration in the middle reaches of the Yangtze River， so as to serve the internal circulation of regional economy and the overall development of urban agglomeration.

Key words: transportation integration; urban agglomeration in the middle reaches of the Yangtze River; economic internal circulation; smart transportation

摘要： 交通一体化能促进生产要素高效流动与整合，有力推动区域经济与社会一体化发展和经济内循环顺利实现。长江中游城市群在交通一体化方面取得很大进展，不仅建立完备的由铁路、公路、地铁、航空、水运等运输方式组成的综合交通运输网络，而且在交通管理与服务方面实现一定程度的信息化与智能化。但长江中游城市群交通一体化建设存在政府与市场配合度不高，缺乏统一的跨区域整体规划和协调机制，各种交通方式互联互通效率低下，智能交通建设落后等困难与问题。可以通过提高政府一体化建设积极性与市场参与度，破除行政壁垒，建立一体化管理协调机制，发展多式联运促进互联互通，增强交通管理与服务的信息化和智能化建设等，进一步推进长江中游城市群交通一体化建设，以服务区域经济内循环和城市群的整体发展。
