What is Vehicle Travel Speed?

[StHenry]

It refers to the average speed of a vehicle traveling on a specific road section. Calculation method of speed: It is the quotient obtained by dividing the length of the road section by the pure travel time of the vehicle (travel time after deducting all stopping times). It is used to analyze the ease of travel and traffic capacity of that road section. Differences between travel speed and trip speed: They differ in nature; their distribution measured values are different; their calculation formulas are different. Travel speed is the average speed of a vehicle traveling on a specific road section. Speed distribution is a numerical value that reflects the dispersion characteristics of speed. Drivers travel according to their personal will on the road but are constrained by other vehicles, road conditions, etc., making it impossible to have a uniform speed. To ensure the accuracy of test data, travel speed usually requires the test vehicle to travel 12 to 16 times on that road section, and the speed value is obtained through statistics. When organizing and analyzing the measured values of speed distribution for trip speed, the sequence is: speed sorting and grouping, which are summarized into 8 to 12 groups. Travel speed is the quotient obtained by dividing the length of the road section by the pure travel time of the vehicle (travel time after deducting all stopping times), used to analyze the ease of travel and traffic capacity of that road section, whereas trip speed is not.

Vehicle speed refers to how fast or slow we drive, usually displayed numerically on the dashboard in kilometers per hour or miles per hour. When driving, I always keep an eye on this speed to avoid speeding tickets, especially on highways where the limit is 120 km/h, while in urban areas it's typically around 60 km/h. Driving too fast can make the car unstable, prone to losing control during turns, and increases fuel consumption and tire wear; driving too slow affects traffic efficiency and may prompt other drivers to honk. Factors influencing speed include engine power, road conditions, and vehicle load – for example, being fully loaded or going uphill can noticeably slow the car down. Safe driving advice recommends staying within speed limits and slowing down in rainy conditions to prevent skidding.

As a new driver who just got my license, I pay special attention to vehicle speed, which represents the rate at which a vehicle moves over a specific time. During initial training, my instructor reminded me to check the pointer or digital display on the dashboard, with units like km/h indicating the distance traveled per minute. Speed calculation relies on wheel speed sensors detecting wheel rotation, which is then transmitted to the ECU computer for display. Excessive speed makes me nervous, making it harder to control braking distance and increasing collision risks; starting too slowly may cause stalling or block traffic. After learning to drive, I realized that smooth acceleration and deceleration are crucial for both fuel efficiency and safety. For example, maintaining around 40 km/h during urban rush hours is appropriate, while also paying attention to speed limit signs to avoid penalty points.

In automotive repair experience, vehicle speed is simply the distance a car travels per unit of time. The engine provides power to drive the wheels, and sensors then convert wheel speed into dashboard readings. I've observed that higher speeds increase engine load and accelerate wear, especially in older models which are prone to overheating. The ABS system relies on speed data to prevent wheel lockup. It's recommended to regularly inspect wheel speed sensors and tire pressure to ensure accurate measurements and avoid false highs or lows. Safety-wise, exceeding reasonable speed limits can easily lead to accidents; for instance, maintaining speeds below 70 km/h on rural roads is advisable for stability.
