actually this your findings There is more than one method. Of course, some are more widely used than others.

After reading this Be more careful on the roads We hope!

Devices called radar measure the speed of vehicles by transmitting electromagnetic waves.

The device points towards the vehicle. It emits radio waves. This wave bounces back from the vehicle and the frequency change in the reflection period determines the speed of the vehicle. This method is used in devices mounted on the side of the road or in radar equipment carried by police teams.

In addition license plate recognition system It is also very effective in measuring speed. Cameras have been placed at two different points on the highway. As the vehicle passes the first of these points, the license plate is recognized and the passing time is recorded. At the second point the process repeats. For example, the average speed is determined based on the distance and time between two points.

If the calculated speed exceeds the legal speed limit, a fine will be imposed.

The most commonly used method is LIDARthat is, it is a laser speed measurement system. This system works with laser light. According to the working logic, the laser light sent by the device hits the vehicle and returns. This rotation time calculates the speed of the vehicle very accurately.

To the radars It takes accurate shots and makes faster detection compared to other devices. Even at vehicle density, it can focus on a single vehicle and measure its speed.

An electronic monitoring system is also part of this work.

Located in areas where speed limits are strictly enforced fixed camerasIt is used to measure the speed of the vehicle instantly. The cameras immediately record the vehicle’s license plate number and speed. If it is determined that the speed limit is being exceeded, a violation report is automatically made.

And finally speed detection pointsThanks to cameras on the side of the road, the speed of the passing vehicle is measured.
