The unobstructed display information refers to information for displaying that the road is in an unobstructed state. The congestion display information is information showing that the road is in a congested state. The early warning processing terminal receives the unobstructed prompt information and displays the unobstructed display information or receives the early warning information and displays the blockage display information, so that whether the road in front of the driver and the passenger on the automobile is congested is prompted, the driver and the passenger can process in advance, and the aim of reducing the probability of continuous congestion after the congestion occurs is finally achieved.

Step S340, obtaining the early warning distance value and the congestion cause information between the position point corresponding to the early warning processing terminal and the position point corresponding to the road congestion information.

The location point corresponding to the road congestion information is a starting location point where road congestion occurs. The early warning distance value refers to the distance between the position point corresponding to the early warning processing terminal and the position point corresponding to the road jam information.

step S354, judging whether the pre-warning processing terminal corresponding to the pre-warning distance value is an automobile internal terminal. If not, executing step S355; if yes, step S356 is executed.

And judging whether the early warning processing terminal corresponding to the early warning distance value is an automobile internal terminal or not, so as to judge whether the early warning processing terminal is positioned on two sides of a highway or in the automobile.

In step S355, the estimated wait time is used as the first warning display information.

Step S356, obtaining the running speed and running time corresponding to the car where the terminal inside the car is located.

The running speed refers to the speed of the automobile with the internal terminal, and the running time refers to the time of the automobile with the internal terminal. When the early warning processing terminal corresponding to the early warning distance value is an automobile internal terminal, the early warning processing terminal is positioned in the automobile. At this time, the position of the early warning processing terminal moves along with the movement of the automobile, so that the running speed and running time corresponding to the automobile where the terminal in the automobile is located are obtained.

And when the predicted waiting time is positioned on two sides of the expressway, the predicted waiting time is directly used as first early warning display information. When the vehicle is positioned in the automobile, the driving early warning display information is obtained according to the driving distance of the vehicle and the continuous blocking probability analysis, and the driving early warning display information is used as the first early warning display information, so that the early warning information displayed by drivers and passengers in the driving process can be updated and changed in real time, and the accuracy of the first early warning display information is improved.

In step S3582, the number of vehicles remaining corresponding to the remaining distance value is obtained.

Wherein the remaining number of vehicles refers to the number of vehicles within the remaining distance value range.

Step S3583, analyzing and obtaining the remaining blocking probability corresponding to the waiting vehicle number and the blocking reference number according to the corresponding relation among the remaining vehicle number, the preset blocking reference number and the remaining blocking probability.

The remaining blocking probability refers to a probability that long-time blocking is still performed easily after blocking occurs in a remaining distance value range, and the remaining blocking probability is obtained through analysis of the number of remaining vehicles and the blocking reference number.

And S3584, re-analyzing and acquiring first early warning display information according to the judging result of whether the continuous blocking probability is consistent with the residual blocking probability.
