Abstract

The invention discloses a highway accident road section early warning method and system based on big data, and the method comprises the steps: vehicle monitoring equipment obtains vehicle information in real time through a Beidou satellite positioning module, and transmits the vehicle information to a management server; in the management server, the vehicle information is monitored, and when the vehicle information shows that the residence time is long, the vehicle is set as a target vehicle, and a warning signal is sent out; according to the position information of the target vehicle, defining a road section behind the target vehicle as an accident road section; and the vehicle in the accident road section is retrieved from the big data database, and a warning prompt is sent to the vehicle monitoring equipment of the vehicle to warn the road section ahead that the accident needs to be noticed. According to the invention, the highway section where an accident occurs can be rapidly detected, a warning effect on rear vehicles is achieved, the rear vehicles are accurately determined, early warning prompt information is accurately pushed, and the occurrence of a secondary accident is avoided; the monitoring is complete, the problem of monitoring omission can be avoided, implementation is convenient, and engineering implementation cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of traffic management, and in particular relates to a method and system for early warning of high-speed accident sections based on big data. Background technique

[0002] Due to the high speed of the expressway, it is necessary to carry out early warning and treatment in time after an accident occurs, otherwise it will cause more serious consequences. The existing processing methods cannot obtain accident information in time and cannot quickly give early warning of accidents, and secondary accidents are likely to occur.

[0003] The existing method is to install detection equipment on the high-speed road section, but this method cannot completely detect and warn the vehicle, has detection loopholes, and has early warning loopholes; and requires engineering construction, which increases the implementation cost of the entire early warning system. Contents of the invention

[0004] In order to solve the abov...
