China tested 200km/h highway technology and maglev vehicle technology for the first time on Monday. The field test carried out on the Gaochun-Yixing Expressway in Jiangsu has achieved phased results, providing technical support for the speed-up of existing expressways and the development of digital transportation in our country.
The Jiangsu Provincial Department of Transportation organized a field test within a 7.9-kilometer range of the Jiangsu section of the Gaochun-Yixing Expressway.
Featuring new highway infrastructure and new transport equipment coordination, the key technology research project focused on 200 km/h expressway alignment index, new maglev transport vehicles, vehicle-road coupling system, mixed traffic organization and collaborative control technology.
For the 200 km/h real vehicle test, digital means are used to realize the precise perception, precise control and precise service of the expressway at the speed of 200 km/h, standardize the design standards for the horizontal, vertical and horizontal sections of expressways under the corresponding speed conditions, and develop new safety protection measures under ultra-high-speed driving conditions.

In order to enrich the technical path for the construction of expressways with a speed of 200 kilometers per hour, the project proposes the technology of linear maglev vehicles and rotating maglev vehicles by developing an integrated control system for suspension, driving and guidance, and conducting real vehicle transformation and testing experiments at the same time so as to transform and upgrade the original structure of traditional automobiles, install suspended guide permanent magnet arrays, and lay good conductor tracks on the corresponding ground.
This test successfully achieved the test goal of a suspension weight of 2.8 tons and a suspension gap of 35 mm for the first time in China.

This research test will provide important support for the research and development of China's maglev vehicles.
