In March 2021, the 14th Five-Year Plan for National Economic and Social Development and the Outline of Long-term Goals for 2035 were released. In the outline, the important requirement of "accelerating the construction of a strong transportation country" is clearly put forward.
The degree of development of transportation is an important indicator of a country's modernization. Li Xiaopeng, minister of transport, previously proposed, "By 2035, we will basically build a transportation power; by the middle of this century, we will build a transportation power in an all-round way." To this end, it is necessary to achieve 'three transformations' and create 'four first-class'. "One of these changes is from relying solely on the support of factors in the past to paying more attention to the support of reform, opening up and innovation."
Innovation support, on the other hand, refers to promoting the autonomy of transportation equipment, aiming at the forefront of science and technology in the world, promoting new energy, intelligence, digitalization, lightweight transportation equipment and complete sets of technical equipment, developing intelligent transportation, promoting the deep integration of new technologies such as big data with the transportation industry, and using new technologies to empower traditional transportation infrastructure, so as to become the main force of new infrastructure.
In terms of innovation support, 51WORLD has never been absent: based on the AES all-factor scenario, relying on the digital twin, uniting the top enterprises and partners in the ecological chain of the transportation industry, constantly innovating, and empowering smart transportation with technology, whether it is "traffic flow simulation from macro, meso to micro", or "highway vehicle and road collaboration", or "holographic intersection cloud control platform", or "smart bus operation scheduling platform", all of which empower industry upgrading with technology.
The following is a list of 51WORLD's top 8 cases in the field of smart transportation, let's take a look at it
