What is the Principle of Vehicle Speed Measurement?

[JesseLynn]

Vehicle speed measurement principle: The average speed measurement system operates through an automatic license plate recognition system. Two adjacent monitoring points are set up on the same road section to record the time a vehicle passes through them. The system then calculates the vehicle's average speed in that section and determines whether it exceeds the speed limit based on the preset standard. To safely pass through an average speed measurement zone: When you see an "Average Speed Measurement" sign by the roadside, reduce your speed to the specified limit and maintain it within the allowed range. If you exceed the speed limit at the starting point, you should try to adjust your average speed to the specified limit during the measurement section. As long as the calculated average speed upon reaching the endpoint doesn't exceed the limit, you won't be penalized for speeding.
