A transient early warning method and device for dangerous road events

Abstract

Embodiments of the present invention provide a transient early warning method and device for road dangerous events, which receive road dangerous events issued by publishers, and determine the early warning levels of road dangerous events according to the dangerous types of road dangerous events. The hazard type and warning level of the dangerous event determine the early warning strategy of the road dangerous event, and finally the early warning strategy is fed back to the driver. The method and device can identify and warn most road hazards without relying on a large number of auxiliary vehicle-mounted equipment or roadside equipment, and the application cost is low and easy to popularize; at the same time, road hazards of different types and warning levels Different early warning strategies are used for early warning of road dangerous events, so that drivers can accurately and intuitively know the information of road dangerous events, so that drivers can respond to road dangerous events in time, and can effectively avoid potential accidents or secondary accidents.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more specifically, to a transient early warning method and device for road dangerous events. Background technique [0002] Cars are an indispensable element in people's lives. According to incomplete statistics, the number of motor vehicles in China has reached 310 million, of which 217 million are cars; the number of motor vehicle drivers has reached 385 million, of which 342 million are car drivers. The driver's driving experience can reduce potential safety hazards during driving, but due to various subjective and objective factors, potential safety hazards during driving cannot be completely eliminated. There is icing ahead and roadside construction ahead on the road and so on. With the development of technologies such as smart cars, unmanned driving, and vehicle-road coordination, how to reduce potential safety hazards during driving has become a hot spot of a...
