The highway is a high-grade highway. China's Ministry of Transportation and Communications "Highway Engineering Technical Standards" stipulates that a highway refers to "a highway that can accommodate an average annual daytime and nighttime traffic volume of more than 25,000 small buses, and that is designed for high-speed automobile traffic with separate lanes, and with full control of access". Although countries name highways differently, they all refer exclusively to highways with more than four lanes, two-way separated driving, complete control of entrances and exits, and the use of all three-dimensional intersections. In addition, there are a number of countries to partially control the entrance and exit, not all the use of three-dimensional intersection of the direct arterial also known as highway.
