As our country gradually stepped into the 21st century. Also into the modern society. China's economic level has increased dramatically, scientific and technological research has also achieved milestones. At the same time, the population of our country also began to increase, because of the large population and the rise of a variety of buildings, the mode of transportation has also thus obtained a great change. In recent years, cars have become a standard part of every family's transportation. However, the car from one aspect of the convenience of people's transportation, but also to human beings brought a huge traffic hazards. Because of the many cars are blocked on the road will eh formation of traffic jams. In order to solve the traffic jam this situation, our country and developed a navigation software, which helps people faster and more convenient travel.

Navigation software is just a software, it is how to get the road information? This is due to the advanced level of science and technology in China. With the popularization of big data in our society, the navigation software also puts these big data to the best use. Because, in our small cars, the body system comes with a positioning system. And during the traveling process of each car, this positioning system will be turned on. When each car's positioning system is turned on, the information will be transmitted to the navigation software. The navigation software will use the information from the positioning system to determine the road conditions.

In addition, there is some cooperation between the navigation software companies and the traffic control departments. They have a mutually beneficial relationship. Because the traffic control department has the role of monitoring the traffic condition on the road. Therefore, the traffic control department will provide the traffic condition information to the navigation software company so that the navigation software can judge the road condition. In turn, the navigation software company will provide the traffic condition of each vehicle on the highway to the traffic control department. This makes it easier for the traffic control department to better manage traffic.

The function of navigation software is very diverse, each car navigation software will record the car's driving process. In the meantime, these conditions on the road will be analyzed and organized by the navigation software. This will help the owner of the car to determine the situation on the road.
