What does average speed mean?

[DeCamilla]

Average speed refers to the average speed of a car over the last 100 kilometers of travel. Below is more information about vehicle speeds on different roads: 1. Highways: On highways, the maximum speed for small passenger vehicles must not exceed 120 kilometers per hour, other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. On roads with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; on roads with three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. 2. Roads: On roads without a central dividing line, the speed limit for urban roads is 30 kilometers per hour, and for highways, it is 40 kilometers per hour; on roads with a central dividing line, the speed limit for urban roads is 50 kilometers per hour, and for highways, it is 70 kilometers per hour. 3. Speed limit of 30 kilometers per hour: When entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, or narrow bridges, making U-turns, turning, or descending steep slopes, encountering fog, rain, snow, dust, or hail with visibility within 50 meters, or driving on icy, snowy, or muddy roads, or towing a malfunctioning motor vehicle, the speed limit is 30 kilometers per hour.

Average speed refers to the overall average speed of a trip while driving, simply calculated as the total distance traveled divided by the total time taken. For example, my commute to work is 30 kilometers. During rush hour with traffic congestion, I might average only 20 kilometers per hour, while on weekends with smoother traffic, it can go up to over 70. I pay attention to this because a high average speed often indicates frequent high-speed driving, which may involve speeding (unsafe) and increased fuel consumption. Conversely, a low average speed suggests heavy traffic congestion, leading to higher fuel consumption and more emissions, which is worse for the environment. The optimal range is the economical speed of 60-80 km/h, balancing fuel efficiency and driving efficiency. When driving a gasoline car, I check the average speed displayed on the navigation or dashboard and adjust my route to avoid traffic jams—such as leaving earlier or later—to save money and reduce pollution. Calculating average speed is also practical for long road trips, helping estimate arrival times.

Average speed refers to the overall average rate at which a vehicle travels over a certain distance. For example, my daily commute is 25 kilometers, taking 40 minutes, which results in an average speed of about 37 kilometers per hour. It's quite important while driving: in the city, with many traffic lights, a lower average speed means more idling and higher fuel consumption; on the highway, a higher average speed might be faster but increases air resistance and fuel usage. My car's GPS navigation often displays it, and if I notice the average speed during rush hours is below 30 km/h, I consider taking the bus instead. Managing the average speed wisely can improve efficiency, saving both time and fuel costs. I recommend drivers pay attention to this metric to optimize their routes.

Average speed is a value calculated by dividing the total distance traveled by the total time, measuring the average rate of the entire journey. I check it in the car through the OBD system or mobile app, which can reflect driving efficiency. A high average speed indicates good road conditions and smooth driving, while a low one may suggest traffic congestion or frequent starts and stops, increasing wear.
