Expressways, referred to as highways, are highways designed for high-speed vehicles. Expressways have different regulations in different countries and regions, in different times, and in different scientific and academic fields. According to China's "Technical Standards for Highway Engineering" (JTG B01-2014), expressways are multi-lane highways that are designed for vehicles to drive in separate directions and drive in different lanes. The average daily designed traffic volume of the expressway should be above 15,000 passenger cars, and the design speed is 80 to 120 kilometers per hour.
