How does navigation know where the traffic jam is?
Nowadays, navigation basically relies on a huge customer base and the big data Internet behind it. As long as there is a small problem in one of the links, it will be detected by the navigation system.
1. For navigation, the more user groups are used, the more accurate the navigation feedback information will be. Suppose a large number of users with high-tech online navigation collectively slow down or stop in a certain period of time, and there is obviously congestion. Then this situation will be detected by the background of navigation, and then the congestion time will be judged by the data processing mechanism in the background. Finally, the data will be transmitted to more online navigation customers through the Internet to remind them to avoid congested roads as much as possible.
2. At present, the navigation system basically cooperates with the traffic control department, and then the traffic control department will share the implementation data * * * from the cameras of each road section with the navigation system, and then the guidance system will share the real-time road conditions * * * with the online car owners through the data processing mechanism according to the information of the traffic control department.
3. In addition to the cooperation between big data and the traffic control department, there will inevitably be some loopholes in the navigation system, so at this time, the navigation system encourages users to send real-time traffic information and then share the data provided by these users with other users.
What do you think of the congestion length of Gaode map?
In order to facilitate users to check the current congestion situation, Gaode Navigation has made color distinction.
Green: it means that the road surface is smooth and there is no congestion, so you can drive with confidence;
Yellow: it means driving slowly, but still moving slowly;
Red: stands for congestion and needs more attention;
Crimson: it means serious congestion, and there may be congestion. It is recommended that the owner try to bypass.
Similarly, the length of congestion will also inform you in the navigation tips, and navigation will also help you budget the transit time according to the length and degree of congestion.
In fact, the current navigation system is not only as simple as guiding the way, but also like a big platform where everyone can share delicious, fun and road information with surrounding users. With the development of big data and the Internet, navigation systems are slowly covering all areas of our lives, enriching our lives.
