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 invention relates to the technical field of vehicles and in particular discloses a road condition prediction method based on road driving events. The following steps are partially or totally executed by a vehicle terminal, and the method comprises the following steps: acquiring position information of vehicles; acquiring vehicle state information of the vehicles; recognizing vehicle driving behaviors of surrounding vehicles and transforming into road driving events; generating a traffic model for characterizing a relationship between the road driving events and road conditions according tothe previous information; obtaining current road conditions of a road area according to a road area to which the position information of the vehicles belongs and the vehicle state information, and predicting subsequent user road condition information of the road area according to the traffic model and the road driving events in the road area; and presenting the user road condition information tousers by virtue of a display screen in the vehicle. By virtue of counterfactual thinking on causes of traffic conditions, traffic condition information in the current area of the vehicle is accuratelydeduced without geographical limitation, and more convenience is brought to the driver.
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: ...
