In the process of driving, on-board navigation is a configuration that many car owners will use. Sometimes even if they know the route, car owners still want to use on-board navigation, so that they can know the specific congestion on the route, and then they can better plan their travel route. However, some car owners will consider such a problem, that is, how does the vehicle navigation know that the road ahead is blocked? On this issue, an expert who knows more about relevant occupations explained the reasons. As an expert said: thanks to the owners.

First of all, traffic congestion is the primary responsibility of the traffic department, because now there are cameras all over the road. If there is congestion, the camera can respond to the background of the traffic department in time, so the congestion there can also be learned in time. As for some navigation systems, they will pay close attention to the news released by the traffic department or cooperate with them, so that they can tell the car owners in time and avoid increasing congestion on the road.

Secondly, for many car owners, if they encounter congestion on the road, they will reflect the congestion to the background of the navigation software. In this way, the background is more reflected by car owners, and the road section will be defined as a congested section. For many enthusiastic car owners, they will actively upload road information when driving, which can not only reduce the number of vehicles and facilitate themselves; Together, it can also prevent other car owners from being blocked again and facilitate others.

In addition, the current vehicle navigation can also be calculated through "big data" to judge whether the road section is congested or not. If the road section is congested, the speed of the car will be very slow when the car passes through this road section. If it is a slow car, it may be occasionally, but if the speed of each car passing through this road section is slow, the road section is likely to be in a congested condition. Therefore, it is also possible to judge whether the road is congested through the driving conditions of many vehicles. It is no wonder that experts will say: thanks to many car owners.

Finally, when judging whether the road is congested or not, many navigation software will predict it by prediction. Just like the weather forecast, each road section is congested at a certain time of the day, or on which days of the month, which can be distinguished by a large number of data analysis, which is also a very effective and scientific method.

It can be seen from this that the on-board navigation can accurately display the road congestion. It is not occasional, but still very scientific. Car owners may wish to refer to the road information on the navigation when traveling, so as to facilitate themselves and avoid making the road congestion more severe.
