Abstract

The present invention relates to a road risk early warning method and device. Data corresponding to dimensions required by a road model is screened out from sample data comprising a plurality of datasources, wherein the data sources comprise map data, traffic data, weather data, automobile company data, driver data and accident data, the data sources are very rich, and based on this, informationof the established road model is more completed. Based on the established road model, each road is subjected to clustering for classification to allow the most similar roads to be classified to one class, therefore, the most similar safety levels are classified to one class, the risk early warning levels of the roads are determined, and the early warning result is more accurate.

Description

technical field [0001] The present application relates to the technical field of road risk early warning, in particular to a road risk early warning method and device. Background technique [0002] With the increase of road vehicles, traffic accidents on the road occur frequently. In order to ensure the safety of people and property during road transportation, early warning of road risk can be carried out. The current road risk early warning model has a single data source, and the early warning effect is not good. Contents of the invention [0003] In order to overcome the problems existing in the related art at least to a certain extent, the present application provides a road risk early warning method and device. [0004] According to the first aspect of the embodiments of the present application, a road risk early warning method is provided, including: [0005] Obtain sample data; the sample data contains multiple data sources, each of which contains at least one dime...
