We travel at high speeds, the most common of which are in three forms, fixed-point, inter-zone and mobile. It's all for speed, but it's different。
It's like an earth cookstove, a gas stove, an electromagnetic stove, which, of course, can be used to cook and cook, but a friend who has used it knows that the experience and usage are really different。
Fixed speed
Let's start with a fixed speed measure, some of which is called a single point speed measurement。
In short, speed measurement equipment, such as radar, laser speed measurement, capture of camera head, etc., is fixed on the front of the gate or on the side of the road, where speed is measured。
Different speed measuring devices work differently. For example, with our usual cameras, it's usually used in conjunction with radar speed gauges。
When some vehicles pass, the speed radar sends an electromagnetic wave in the direction of the vehicle
The radar signal, which is proportional to the vehicle's speed, was received at that time, and technical processing allowed the instantaneous speed of the target vehicle。
When the speed of the vehicle was detected, the camera was "painted" to capture the vehicle's license plate。
Since it's fixed, isn't it slow to see the speed gauge go ahead of the brake? Is it working
If it's a camera, it's a bit of a hope, as we used to tell you in the video。
The effective surveillance range of the speed cameras is about 60m, and we can identify the approximate contours of the object when we see 250 to 270m。
In other words, if you see a camera in front of you at this point, there is a real chance that you won't get caught at speed。
However, if the brakes are successful, the vehicle in the back does not necessarily react and is likely to be followed。
And now, the map navigation usually has a hint for the speed of a fixed point, so let's take a little more notice, watch out, control the speed ahead。
And there's no need to wait for the "ooh" camera, "push" down and "bong" tailed。
Inter-area speed measurement
The second is what we're talking about, and there are places where we've been de-targeting, and we're afraid we'll have to test the car, right? Turn it into an inter-zone。
In shandong province, for example, since 1 october 2020, all 594 single-point speed-detection devices on highways throughout the province have been suspended and fined, while 132 inter-block speeds have been activated。
What it means, what it means, what it says, what it says, what it measures in a section。
Lee, wang guangcheng and others published a paper in the journal industrial metrics, “exploration of speed monitoring systems for motor vehicles”。
It says, "intersectional speed measures reflect the average speed of cars travelling between two or more sections of a road。
The evasiveness of single-point speed measurement was effectively addressed, with a clear effect on the control of the speed of dangerous sections。
In other words, it's designed to make up for our “failure” and the lack of single-point speed。
It's like in college, teacher calls, so many people just leave
That's why the teacher changed his name to a district name, right? One lesson, one in class, one in class, one in class, one at the end of class, you're all counting, almost。
Some friends start shaking again at this point: "the first half of the speed, the second half slows down, or the first half of the day off in the service sector is definitely not going to be speeding."
It does not work well, and inter-district speeds are measured in steps, each with a camera. If they get caught, they'll still be speeding。
Zhejiang high-range traffic police, in response to questions from netizens, also mentioned that inter-district speed measurement “onboard” does not mean that other speed-measurement systems “offline”, and that fixed speed, mobile speed measurement or inter-district speed measurement complement each other。
There is a saying on the internet that as long as the starting point is not speeding, it will not be filmed, and then the end speed is filmed, and there is no way to measure the average speed。
In fact, there is no basis for the ga/t 959-2011 technical instructions for speeding between motor vehicle zones, which contain clear requirements: inter-zone speed starting and end-control devices have a vehicle image capture rate of more than 95 per cent。
In short, the starting point cameras must be able to capture more than 95 per cent of the vehicles passing to qualify。
There are no cases in which it is said that it will not be taken or done without speeding, and virtually every car was photographed in the past。
Move speed
Finally, mobile speed measurement, also known as "mobile speed measurement". It's called moving speed, but it's not what we think。
The traffic police found a random section of the road, and looked around, like a “mine-laying” and threw it there。
First, what sections are to be added to mobile speed gauges, at what speed limits, are to be made public and are generally notified in the official accounts of the traffic police or in local newspapers。
Second, moving speed points are also required to place warning signs in advance, and people will tell us that there are speed points ahead。
Guidance on the regulation of traffic violations by motor vehicles in the context of speed limit, issued by the transport administration of the ministry of public security in 2013。
It contains provisions to use mobile speed gauges, which must be marked at 200 m above the speed gauge point of the direction to which the vehicle is arriving, and which must not be concealed or concealed for any reason。
Thus, there is no deliberate scavenging, year-end impulses, speeding cars and fines for income generation。
The core function of three speeds is similar
In general, the difference between fixed-point, inter-zone and mobile speed is true, but in the end, the core function is the same, so let's not go too fast and drive well, right
As long as we're moving at normal speed, no matter how it's captured, don't worry, right
It's called the “quickest”, the slowest is speeding, and on the second day i woke up and saw the hospital ceiling. That's lucky, isn't it
Why didn't you watch out for speeding
When it comes to speed measurement, a lot of friends in the background say, "sometimes i'm going to "scrambling" and "scramble" and go back and check it out, like i haven't texted it."
"it doesn't seem to have been punished, so what does it mean to shoot me twice and leave me twice?"
In addition to speeding, it's actually slow, slow and tortoise on the road, and it's even more annoying。
It's on the left-hand side of the road. Why open 60 or 80? I almost hit 120. Is there anything i can do to cure them? Of course, it must be reasonable, legitimate and in compliance。
I've made a video of all the information and the subject matter, and i've prepared a dry product。
If it's easy to see, focus on the "stand-by car" and answer the key word "high speed"。
Every day, you'll be given a piece of automobile dry stuff, text, audio, video, just pick the version you like, and you'll be waiting to play。
