Is the 80 km/h speed limit accurate on highway section speed measurement?

[OTheo]

Accurate, drive according to the speed limit. Here are the specific details: 1. Section speed measurement: To reduce speeding, there are speed cameras. On plains or main highways, real-time speed cameras are installed at intervals. In some mountainous areas, section speed measurement is used to monitor vehicle speeds for cost reduction. To avoid being caught by section speed measurement, it's important to understand how it works. 2. Working principle: The principle of section speed measurement is very simple. Two monitoring points are set up at the two ends of a section. When a vehicle passes the first monitoring point, the time is recorded. When the vehicle reaches the second monitoring point, the end time is recorded. The vehicle's travel time over this section is compared with the preset time to determine if it exceeded the speed limit. 3. How to deal with it: The most effective method is not to exceed the speed limit. Speed limits can effectively avoid safety hazards. There are many accidents on highways, and nine out of ten accidents are caused by speeding. Driving within the speed limit is the safest and most appropriate method.
