Most of the early real-time navigation information came from the cameras provided by the traffic control department to monitor the road information, but because of the limited access and open mode, third-party navigation software companies could not fully realize real-time.
Nowadays, the loading rate of GPS locators is very high, and it is very easy to obtain data. Through the tens of thousands of traffic information reported by users every day, and the cooperation with the government and traffic management, the causes of congestion and traffic events such as accidents, control, and construction are almost covered, and then the map will adjust or remind the route in the navigation planning. GPS locators can be used as a source of real-time information on road conditions.
GPS locator floating car technology, also known as "probe car". According to the position, direction and speed information of the floating car equipped with the vehicle-mounted global positioning system, the position, direction and speed of the vehicle are regularly recorded during the driving process, and the relevant calculation models and algorithms such as map matching and path estimation are used for processing, so that the position data of the floating car and the urban road are processed. It is related in time and space, and finally the traffic congestion information such as the vehicle speed of the road that the floating car passes through and the travel time of the road are obtained. This method is very accurate when there are enough vehicles in an area.
Ultrasonic (radar) monitors can monitor the working conditions of road vehicles by transmitting wave-frequency signals at fixed points. They can mainly monitor traffic flow, occupancy, and vehicle presence. They are usually laid on highways and main roads.
The real-time road condition of the road is to transmit the data collected by the above technologies back to the background of the navigation system. After calculation and analysis, the real-time road condition is fed back to the user terminal. Usually, the traffic congestion is indicated by color: green means smooth, yellow means a little congested, red means Serious congestion.
