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
