According to reports, the research was organized by the Jiangsu Provincial Department of Transportation. The test was carried out within a 7.9-kilometer range of the Jiangsu section of the Gaoxuan Expressway, covering a multi-level speed limit section of 140-160-200 kilometers per hour.
8 test vehicles, including 5 new energy vehicles and 3 conventional energy vehicles,8 drivers of different ages and genders were recruited from social channels, and the maximum speed of the real car was once close to 230 km/h.
However, this test is not aimed at car performance, but a study of road design and usage standards. The test results 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, which provide important information for the safe and efficient operation of expressways at a speed of 200 kilometers per hour. Assure.
At present, the upper limit of the speed of China’s expressways is 120 kilometers per hour, and there is a lot of discussion on whether the expressway should be accelerated.Jiangsu completed the 200-kilometer road test this time, laying a foundation on the technical level.
Zhou Haitao, the former chief engineer of the Ministry of Communications who participated in the test, said that under the existing driving environment of 120 kilometers per hour on conventional highways, based on more advanced digital transportation and new infrastructure technologies, the stock potential of highway traffic efficiency should be further tapped to meet the speed of 140 kilometers per hour. -200 kilometers of personalized traffic needs.
