Navigation is not long eyes , how does it know that the road is congested? Is it really just satell

With the continuous development and progress of science and technology, our lives have become more and more convenient, take mobile phone navigation as an example, when there was no mobile phone navigation before, we need to see the road signs, we are easy to get lost without road signs, so in the past, we often call those drivers who are very familiar with the road "live map". But now we rarely hear such a statement as a live map, because now with the navigation system, we go ** as long as you enter the destination, the navigation will automatically generate a driving route, we can be very assured and safe to follow the drive, but some netizens raised a question, navigation and no eyes, how does it know that the road ahead is congested? Can it really be determined by satellite positioning?

Let's take a look.

We all know that the essence of mobile phone navigation lies in satellite positioning, which is what we often call GPS, without GPS positioning system, navigation is equivalent to being blind, and we cannot identify our location at all. In fact, the satellite positioning system also has a more advanced function, which can directly calculate the traffic flow and other conditions, so as to determine whether there is a traffic jam ahead. To put it simply, the original smooth road can be passed in 5 minutes, but today almost all cars take 30 minutes to pass, so the positioning system can judge the road congestion ahead, and display the congestion on the navigation in advance to remind the driver.

For example, under the same road conditions, there are 99 people using the map, and only 1 person using the AutoNavi map, then the map will show the congestion of the road section, and the people using the AutoNavi map will show that there is only one car on the current road, and the road is smooth and feasible, which is the gap reflected by big data.

Secondly, the real-time traffic conditions on the mobile phone navigation, in addition to relying on satellite positioning, it also has a close relationship with the traffic management department, usually the mobile phone navigation will cooperate with a variety of traffic departments, the traffic department provides real-time traffic data, and sends it to the mobile phone navigation, such as the front construction, traffic restrictions, traffic accidents, etc., so that the real-time road conditions on the mobile phone navigation are very diverse.

Compared with mobile phone navigation, car navigation is relatively single, almost all car navigation on the market is offline, navigation can only display the route, no real-time road conditions, not to know the traffic jam. Only the ** navigation on the mobile phone has such a function, so now many friends do not use it even if there is a navigation in the car, but open the mobile phone navigation to use.

The reason why it knows about road congestion is because it implements a monitoring system on the road, and it does not have a monitoring system personally, but there is a road condition status at the headquarters, so as to reflect it to it and let it tell the user, so as to bring convenience to the user.

I think there should be a camera, and it doesn't rely entirely on satellite positioning, and the relevant staff should be able to see the situation at the time through the video and make a certain judgment.

No, if the signal flow on a road is very large, and the flow is slow, it means that there is a traffic jam, and now it is identified by big data.

The key element of navigation is indeed satellite positioning, also known as GPS. If there were no satellite positioning, there would be no navigation. Therefore, navigation is to know the road congestion ahead through satellite positioning.

Through the judgment of the road ahead, navigation can basically predict whether the road is congested, which really depends on satellite positioning.

Navigation can accurately determine the time of our arrival, and it can also be estimated whether the road ahead is congested, which is estimated based on large data, although this is only a kind of **Although it is not necessarily absolutely accurate, with the help of big data, it is as accurate as possible

The navigation system will comprehensively consider the traffic capacity of the area according to the number of users, density, driving speed and other data, and then divide it into several levels of congestion, congestion, and severe congestionUsually in the case of congestion ahead, the navigation system will alert us and let us take a detour to avoid delaying time.

Navigation mainly relies on satellites to report road conditions in real time, and satellites in space can detect the implementation of the road you are walking at any time, and then tell the driver through navigation voice!

Navigation does not have long eyes, he wants to know the road congestion ahead, relying on the navigation detector, machine recognizer, and now cars have this recognition function.

Navigation detection congestion is located by other users' navigation software, and when the navigation users in front of them collectively move slowly, it means that there is congestion in front of them.

Because the navigation is located by GPS satellite, the navigation can quickly identify the road conditions ahead and feed back to the navigation in time.

Although navigation does not have long eyes, the satellites that support navigation operation, they are watching from the sky. They can monitor each road section, is there a lot of cars now, is it smooth?

Although there are no eyes, car navigation informs the driver of the road congestion ahead or the path ahead based on the message detected by the satellite signal.

Because the vehicle is driving, the GPS position and speed and other data will be uploaded to the background of the navigation software, and the background can calculate the current road congestion state through the analysis of the speed of vehicles passing in the area through the system, and update the map data in real time.

Because it's connected to a satellite, the satellite transmits the road ahead to the navigation, so they know about it.

How does the mobile phone navigation know that there is congestion ahead? Is it really satellite observation? We were all wrong.

How does the mobile phone navigation know the traffic jam ahead? You think it's a satellite observation, we're all wrong.

How does mobile phone navigation know that there is congestion ahead, it is really satellite observation, we are all wrong.
