The principle of "interval speed measurement" on the highway is very simple

Many car owners like to take the highway when traveling by car, because they can reach their destination faster. However, vehicles travel very fast on the highway, and some car owners even drive at high speeds on the highway, causing traffic accidents.

In order to increase control over automobiles, relevant departments have installed interval speed measuring equipment on highways to detect whether drivers are speeding. So how is the speed measured on the highway? Next, the editor will give you a brief analysis.

There is a big difference between the interval speed measuring device and the ordinary speed measuring device. The ordinary speed measuring device measures the instantaneous speed of the car owner, while the interval speed measuring device measures the average speed of the car owner driving on a certain road section. For example, the distance between two speed measuring points is 120 kilometers, but the maximum speed limit on the highway is 120 kilometers per hour. Then the time it takes us to run 120 kilometers cannot be less than one hour, otherwise we are speeding.

This is also the reason why many car owners are accused of speeding despite not speeding when passing speed cameras. Although your instantaneous speed is not over the speed limit, your average speed is.

So how is the speed measured in the interval speed test? Interval speed measurement generally sets a starting point and an end point on the highway, and then determines the average speed of the car owner by detecting the time when the vehicle enters the starting point and end point, thereby determining whether the car owner is speeding.

Once a car is detected to be speeding by the zone speed test, the traffic command center will immediately receive relevant information about the vehicle, so everyone must not take chances.

However, now the speed limit signs on the highways will indicate the speed limit in kilometers. When we see this sign, we should slow down in advance.

In addition, when we pass the zone speed measuring device, we should not start with a speed of 120 kilometers per hour, and then drop the speed to 80 kilometers per hour, although our average speed is not overspeeding. However, in addition to the section speedometer on the highway, there is also an instantaneous speedometer. When our speed reaches more than 120 kilometers per hour, we will also be judged as speeding, so everyone should try not to speed when driving on the highway. When we drive on the highway, in addition to paying attention to the zone speedometer, we also need to pay attention to these other devices. The first is the emergency lane capture patrol aircraft. Some drivers drive in the emergency lane for a long time for the convenience of driving, but the emergency lane is used by vehicles in emergencies. The emergency lane capture patrol machine will automatically capture vehicles driving in the emergency lane and impose corresponding penalties on them.

Secondly, when driving on the highway, we should pay special attention to the mobile speed measuring device. The traffic police will use the mobile speed measuring device to measure the speed of the car from time to time. You may be captured without paying attention, and then you will Received a ticket.
