The early warning information is information for controlling the early warning processing terminal to display that the road is in a blocked state after the road is blocked. When the real-time traffic state information is road congestion information, the road is in a congestion state at the moment, early warning information is obtained through road congestion information analysis, and the early warning information is output to an early warning processing terminal, so that congestion of the road in front of drivers and passengers on the automobile is prompted.

And step S400, the early warning processing terminal receives the unobstructed prompt message and displays the unobstructed display message or receives the early warning message and displays the blockage display message.

The unobstructed display information is information for displaying that the road is in an unobstructed state. The congestion display information is information indicating that the road is in a congested state. The early warning processing terminal receives unobstructed prompt information and displays unobstructed display information or receives early warning information and displays blockage display information, so that whether a road in front of drivers and passengers on an automobile is blocked or not is prompted, the drivers and passengers can process the information in advance, and finally the purpose of reducing the probability of continuous congestion after the congestion occurs is achieved.
