Embodiments of the disclosure provide a warning method and an apparatus for a driving risk, a computing device and a storage medium. In an embodiment, driving behavior data of a driver in a first time period is obtained, and a correspondence between a quantity of occurrences of preset driving behaviors of one or more drivers and a quantity of an actual occurrence of preset scenarios to the one or more drivers while driving is obtained. Based on a quantity of actual occurrences of the preset driving behaviors of the driver, indicated in the driving behavior data of the driver, and the correspondence, it is predicted a target quantity of times the driver is predicted to encounter one or more preset scenarios in the first time period, and warning information is generated based on the target quantity of times.

A target dangerous travel scene existing on a target road section is acquired. Reference information corresponding to the target road section is acquired. The reference information is determined according to a detection record corresponding to each of N dangerous travel scenes detected on the target road section within a target time period. N is an integer greater than 1. The detection record corresponds to each dangerous travel scene being used for reflecting time at which the corresponding dangerous travel scene is detected. An associated dangerous travel scene correlated to the target dangerous travel scene from the N dangerous travel scenes is determined according to the reference information. A prompt operation according to the target dangerous travel scene and the associated dangerous travel scene is performed.
