Abstract

The invention discloses a method, a device and a system for predicting a segmented road risk level and a storage medium. The method, the device and the system are helpful for better predicting the segmented road risk level. The method comprises the following steps: acquiring environmental characteristics of a to-be-predicted segmented road; wherein the environmental characteristics of the to-be-predicted segmented road comprise dynamic characteristics, road characteristics of the to-be-predicted segmented road and road characteristics of associated segmented roads, wherein the dynamic characteristics comprise at least one of time characteristics or weather characteristics; the associated segmented road is a segmented road bordered with a to-be-predicted segmented road; and inputting the environmental characteristics of the to-be-predicted segmented road into the road risk level prediction model, and predicting the risk level of the to-be-predicted segmented road corresponding to the environmental characteristics of the to-be-predicted segmented road based on the corresponding relationship between the environmental characteristics and the risk level.

Description

technical field [0001] The present application relates to the technical field of segmented road traffic safety, in particular to a method, device, system and storage medium for predicting the risk level of segmented roads. Background technique [0002] The prediction of the risk level of segmented roads can not only provide support for the early warning of the transportation industry, police deployment and control, and the selection of segmented road signage points, but also provide early warning information for segmented road users. [0003] At present, the method of predicting the risk level of road segments is mainly as follows: obtain the accident volume per unit time and unit road section, and then use clustering methods to obtain accident-prone places. The method is limited in coverage of segmented roads for which risk levels can be obtained and must rely on historical accident data. The accuracy rate is low when predicting the risk level of the segmented roads in the...
