What does speed measurement mean?
2 Answers
Vehicle speed measurement refers to calculating the distance a car travels per hour. In daily driving, it generally involves four types of speed measurement methods: fixed speed measurement, mobile speed measurement, interval speed measurement, and hidden speed measurement. Four types of speed measurement methods: Fixed speed measurement: Fixed speed measurement involves traffic police departments setting up speed measurement devices at certain locations that require monitoring to detect and capture speeding vehicles. Mobile speed measurement: Mobile speed measurement involves traffic police departments setting up movable speed measurement devices at temporary locations that require monitoring, but the specific location may vary. Interval speed measurement: Interval speed measurement involves setting up two adjacent speed measurement points on the same road section. The average speed of a vehicle on that road section is calculated by measuring the time it takes for the vehicle to pass between the two points, and whether the vehicle is speeding is determined based on the speed limit for that road section. Hidden speed measurement: Hidden speed measurement involves traffic police departments setting up speed measurement devices in concealed locations to detect and capture speeding vehicles. Penalties for speeding: Exceeding the speed limit by 20% but less than 50% results in 12 penalty points, a fine, and a warning; exceeding the speed limit by less than 10% is temporarily not penalized; exceeding the speed limit by more than 10% but less than 20% results in a fine and 3 penalty points; exceeding the speed limit by more than 50% but less than 70% results in a fine and 12 penalty points, and the driver's license may be revoked.
Speed detection is the method used by traffic police to monitor vehicle speeds on the road, mainly including fixed speed detection and mobile speed detection. Fixed speed detection refers to cameras installed at intersections or roadside, like those square devices with flashing lights we commonly see while driving, which automatically capture speeding vehicles 24/7. Mobile speed detection involves temporary speed measuring devices set up by traffic police in sections prone to speeding, sometimes even hidden in green belts. The ultimate purpose of both methods is to encourage drivers to maintain reasonable speeds, avoiding situations like failing to brake in time or losing control during turns due to speeding. Especially during rainy or snowy weather when roads are slippery, speeding is more likely to cause rear-end collisions. With over a decade of driving experience, I've developed the habit of slowing down whenever I see speed limit signs, as arriving safely is far more important than saving time.
