Friends who drive all know that there is something called interval speed test on the highway. There must be friends who have received zone speed tickets, but only a few of them know what happened. In fact, the principle of "zone speed measurement" on the highway is very simple, but many drivers are deducted points because they do not understand it.
What is interval speed testing?
Interval speed measurement refers to setting up two adjacent speed measurement points on the same road section. After testing the time difference between the same vehicle passing two speed measurement points, the average speed of the vehicle during this period can be calculated.
To put it simply, it depends on whether your average speed between these two points exceeds the speed limit of that road section. How does
interval speed test work?
Interval Speed Test will install a set of capture devices at the head and tail of the speed measurement area to capture a photo when you enter and exit. Combining the time when the two photos were taken and the time it takes for the vehicle to pass the road section, the background will directly and automatically calculate your average speed on the road section, compare it with the maximum speed limit of the road section, and finally determine whether your car is speeding on the road section.
Calculation formula: average speed of interval speed = interval distance ÷ running time
For example, assuming that the interval speed measurement distance is 30km long, the maximum speed limit of this road section is 120 km/h.
is calculated according to the maximum speed limit: 30÷120=0.25 hours=15 minutes.
In other words, if you spend less than 15 minutes on this journey, you are speeding and a ticket will follow.
Avoid two misunderstandings in layer speed measurement
1. Having said so much, some friends will definitely think: Since it is the average speed, and I have already exceeded the speed limit, then I will run slowly behind, or I will run slowly first, and then run at high speed for a while. Wouldn’t it be okay?
It is difficult for you to go faster or slower for a while. The only thing you can adjust is to avoid being caught violating the rules.
Moreover, running at high speed is too slow. If the speed is lower than the minimum speed limit, it is easy to cause a rear-end collision and you will also be punished.
2. Then some friends may wonder: Can you avoid being photographed by changing lanes midway?
is useless. Nowadays, the cameras used for zone speed measurement are all high-definition, and the viewing angles are all wide-angle. The monitoring equipment of each lane is aggregated into the system for identification, and the images taken by any lane are the same.
How to avoid being caught speeding by zone speed test?
drives smoothly at the prescribed speed.
It should be noted that no matter what method you take to avoid shooting in the interval speedometer , such as changing lanes or delaying time, the effect will be insignificant. In fact, the best way is to avoid speeding and drive steadily at the prescribed speed. You don't want to be fast or slow, and don't take chances and slow down in the future.
avoids temporary braking and deceleration.
In the past, only when speed was measured at fixed points, car owners could install an "electronic dog" to predict the speed measuring point in advance, or often take this road to find where there was a speed measuring point. Once he reached the speed test point, he immediately braked and slowed down so that he could pass the test.
For interval speed measurements, the temporary braking routine is useless.
When driving, please don’t be opportunistic. Don't even think about speeding when you get on the highway. As long as you can reasonably abide by the traffic rules, keep the warning bell in mind, and travel safely!
