Highway middle lane speed limit is 90-110 km/h. The following is a detailed introduction about vehicle speed: Overview: Vehicle speed refers to the distance a vehicle travels per unit time, abbreviated as speed, commonly measured in km/h or m/s. Vehicle speed is one of the three key parameters in describing traffic flow and holds significant importance in traffic flow theory research. Others: Vehicle speed can also broadly refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, section speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and to ensure their coordination.
