The speed measurement method of rat catching is different between the city center and the region

There are two types of crackdowns for speed violations called "rat captures".For speed measurement, a “optical unit” that uses a photodeline sensor installed on the road, and a “radar type” that irradiates radar waves from the side of the road.It is said that the rat catching is high in the city center, and there are many radar type in rural areas.Let's take a closer look at the mouse catching mechanism.

The mouse catching is also carried out by white motorcycles

The "rat capturing" of the manned speed violation crackdown is a tough entity for multiple police officers to cooperate.In addition to the transportation section of the police station, it is also difficult to deal with the goddess of deity because the white motorcycle members of the transportation riot police are also implemented.

First of all, the flow of the rat catching is that when the car that is more than the set speed is detected, the headset of the current clerk responds with "Pet".The suspension guidance clerk stops the violation vehicle based on the car number that the current recognition has announced.

At that time, the dynamic visual acuity is highly required by the current clerk.You have to identify the number of the car that has exceeded the speed.In fact, the dynamic visual acuity of the current clerk is quite high.You can grasp the number, car model and characteristics, and those who are on board.

Speed measurement point of photocellate mouse catching

The devices used by this current clerk for speed measurement include optical and radar type.The optical electrical type is set up at 3m at 3m intervals.This is a mechanism to measure the speed of how many seconds you pass during this time and measure the speed.It is often seen in the city center.

Since the optical light type needs to be installed on the road, it is common to install a pylon nearby so that motorcycles and the like do not collide.Since the speed measurement point of the optical light type is next to the current recognition, it is highly possible that if you find a pylon and slow down, you will not have to violate it.

On the other hand, the radar formula is 10.Hit the 525GHz radio waves on a driving car and measure the speed by changing the frequency that bounces.It is a rat catching that is often seen in rural areas.Since the speed is measured several tens of meters before the current staff, it is already too late even if you noticed the current recognition and decelerated.Always pay attention to too much speed and try to drive safely.
