The continuous development of advanced technologies such as big data,artificial intelligence,cloud computing,Internet of things and intelligent terminals provide useful big data resources and technical support for the integrated,intelligent and wise development of integrated transportation.Aiming at the cruxes of integrated traffic planning and design,operation management and control,safety and environmental protection maintenance,and logistics service,such as poor quality of heterogeneous data,isolated information island,low degree of mining,etc.,the key technical points needed to be broken through in the development of basic technology and application technology of big data for integrated transportation were prospected,and some references for a better and more systematic application of big data in integrated transportation were provided.
