Building China into a country with strong transportation network is the general grasp of the transport work in the new era. Building China′s strength in transportation with "satisfaction of the people, strong support, and the forefront of the world" has also put forward new requirements for the development of smart transportation. In order to better conform to Outline of Building China into a Country with Strong Transportation Network and further clear and definite the development trend, firstly, the changes in technical, business and performance characteristics of smart transportation were analyzed on the basis of further understanding the requirements for building China into a country with strong transportation network. Secondly, the development trends of new technologies that support smart transportation were reviewed such as big data, internet, artificial intelligence, blockchain, and supercomputing, as well as the development trend that the new technologies were being deeply integrated with the demand of smart transportation was pointed out. Thirdly, combined with the technical accumulation and research direction of the author team, the exploration examples of the application of some new information technologies such as BIM(Building Information Modeling), VR(Virtual Reality), digital twins, AI(Artificial Intelligence), etc. in smart transportation were introduced. Lastly, the development trend of smart transportation under the background of Building China into a country with strong transportation network was forecasted. The research result indicated that the development of smart transportation in the new era should strengthen the key technology research and development at the forefront, create a transportation technology innovation system with vigor and vitality, and promote the development of transportation from relying on traditional factors to more innovation-driven model, thus comprehensively support the building of China′s strength in transportation.
