Friends who drive know that there is a thing called zone speed test on the highway. Some friends must have been fined on the zone speed test, but only a few friends know how it works. In fact, on the highway The principle of "zone speed measurement" is very simple, but many drivers are deducted points because they don't understand it.

Today, Lun Gu is here to talk to friends about zone speed testing. I hope it will be helpful to everyone when driving on the road.

What is interval speed testing?

Interval speed measurement means that two adjacent speed measurement points are set up on the same road section. By measuring the time difference between the two speed measurement points when the same vehicle passes , the average speed of the vehicle during this period is calculated.

To put it simply, depends on whether your average speed between these two points exceeds the road speed limit. How does

interval speed test work?

Interval speed measurement will install a set of capture equipment at the beginning and end of the speed measurement area. will capture a photo when entering and exiting. Combined with the two photo taking times and the time required for the vehicle to pass through this section of road, the background will directly and automatically calculate your compares the average speed in this section with the maximum speed limit in this section, and finally determines whether your car is speeding in this section.

Calculation formula: The average speed of the interval speed test = interval distance ÷ running time

Give an example: Assume that the interval speed measurement distance is 30km long, and the maximum speed limit on this road is 120km/h.

Calculate the passing time based on the maximum speed limit: 30÷120=0.25 hours =15 minutes

In other words, As long as the time it takes you to pass this distance is less than 15 minutes, it will be considered speeding, and a ticket will follow.

2 misunderstandings about escaping the interval speed test

. Having said so much, some friends must be thinking: Since it is calculating the average speed of , then if I am already speeding, I will run slower behind me, or I Let’s run slowly first, and then I’ll race on the highway for a while. Then I’ll be fine, right?

What Lungu wants to tell his friends is that this section of the road may not only have interval speed measurement as a monitoring method, but may also have fixed speed measurement, mobile speed measurement , GPS speed measurement, etc. that cooperate with each other. These technological equipment are not easy to eat. A jobber.

It is also difficult for you to pass fast and slow for a while, and adjust it just enough so that you will not be photographed violating the regulations.

and are running too slowly at high speed. If the speed is lower than the minimum speed limit, it will easily cause a rear-end collision and will also be punished.

. Then some friends may think: Can I avoid being photographed by changing lanes in the middle?

This is useless. The current zone speed measurement cameras are very high-definition, and the viewing angle is also wide-angle. The monitoring equipment of each lane is aggregated into the system to identify . The captured will be the same no matter which lane it is.

How to avoid being caught speeding by the zone speed test?

Driving steadily at the prescribed speed

It should be noted that no matter what method you use to avoid the shooting of the speedometer, such as changing lanes or delaying time, the effect is not great. In fact, the best way is to avoid speeding. Drive steadily according to the prescribed speed, do not go fast and slow suddenly, and do not take chances of slowing down later.

Avoid the situation of temporarily braking to slow down

In the past, when there were only fixed-point speed measurement, car owners could predict the speed measurement point in advance by installing an "electronic dog", or they could often walk this stretch of road and find out where the speed measurement point was. It's almost time to reach the speed test point. You should brake immediately to slow down, so that you can pass the test.

With zone speed measurement, the trick of temporarily braking is useless.

Lungu summary:

During driving, no one should act opportunistically or act smart. Don’t think about speeding on the highway. As long as you can reasonably obey the traffic rules and keep the safety alarm in your heart, you can truly travel safely!
