How many kilometers is a one-hour drive?

[ElleLynn]

Driving speed varies, so the distance traveled in one hour also differs. Below is an introduction to driving speed: 1. Introduction: The distance a vehicle travels in a unit of time, referred to as driving speed. The commonly used units are kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. 2. Function: Vehicle speed can also broadly refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. 3. Legal speed limits: According to the 'Road Traffic Safety Law' and its implementation regulations, on roads without a central dividing line, the speed limit is 40 kilometers per hour; on roads with only one motor vehicle lane in the same direction, the speed limit is 70 kilometers per hour; when entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, narrow bridges, or when making U-turns, turning, or descending steep slopes, the speed limit is 30 kilometers per hour. The maximum speed limit on highways is 120 kilometers per hour.
