Problems solved by technology
[0003] However, the above-mentioned method generally has the following problems: 1) the measurement accuracy is not enough. In the prior art, the real-time road congestion situation obtained by the road image monitoring equipment can only roughly infer the follow-up traffic condition information macroscopically, and its result is quite different from the actual situation. Therefore, it is impossible to effectively and timely predict the follow-up traffic conditions, and the guiding significance for follow-up vehicles is limited; 2) Due to the limitation of the monitoring area, traffic flow monitoring can only be realized in areas where road image monitoring equipment is installed, and the application range is limited

The present invention relates to the technical field of vehicles, and specifically discloses a method for predicting road conditions based on road driving events. The following steps are partially or completely performed by a vehicle terminal, including: obtaining vehicle position information; obtaining vehicle state information of the vehicle; identifying The vehicle driving behavior of surrounding vehicles is converted into road driving events; according to the above information, a traffic model representing the relationship between road driving events and road conditions is generated; the current road conditions of the road section area are obtained according to the location information of the vehicle, the road section area to which it belongs and the vehicle state information, and According to the traffic model and road driving events in the road section area, predict the subsequent user road condition information in the section area; present the user's road condition information to the user through the display screen in the vehicle. By reversely thinking about the causes of traffic conditions, the traffic condition information in the current area of the vehicle can be calculated more accurately, and it is not restricted by region, bringing more convenience to drivers.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a road condition prediction method based on road driving events. Background technique [0002] As urban road traffic congestion becomes more and more serious, the government has also invested a lot of manpower and material resources to improve road infrastructure. All important traffic road areas in big cities are generally equipped with fixed road image monitoring equipment to monitor the speed and flow data of road vehicles. The road monitoring command center understands each area through the road images collected and uploaded by the road image monitoring equipment. Real-time conditions on the road surface, so that the follow-up traffic condition information can be estimated according to the traffic flow, and the number of vehicles at each intersection can be adjusted to ensure smooth traffic. [0003] However, the above-mentioned method generally has the following problems: ...
