Problems solved by technology

However, the accident vehicles in traffic accidents are not equipped with equipment such as driving recorders. Even if a driving recorder is installed, there is still a certain collection angle of view. In addition, due to the limitation of the scale of the project, not all road sections are equipped with cameras. There are certain limitations in the intelligent judgment of traffic incidents based on image information or video information

Embodiment 1

[0060] Embodiment 1: the method for judging traffic incidents based on semantic analysis, such as figure 1 As shown, it is specifically implemented by the following steps.

[0061] S1: Obtain voice information describing the traffic event by each event party in the traffic event.

[0062] The voice information acquisition process is as follows: according to the type of accident, the corresponding voice description template is called, and the voice description template is arranged by multiple sub-category modules according to the logic of the accident; each sub-category module matches and uploads the associated professional terms from the database for display; The voice information is recorded when the sub-category module is opened, and is classified and saved when it is closed.

[0063] It should be noted that the sub-classification module includes but not limited to road type, intended driving type, and accident type. When the accident party provides voice information, it ca...

Embodiment 2

[0079] Embodiment 2: A traffic incident evaluation system based on semantic analysis, including a voice acquisition module, a semantic analysis module, a first evaluation module, and a second evaluation module. The voice acquisition module is used to acquire the voice information of the description of the traffic incident by each event party in the traffic incident. The semantic analysis module is used to extract the features of the voice information through the semantic analysis method to obtain subjective information, and perform feature classification on the subjective information to obtain road distribution information, intentional driving information, and event occurrence information from the corresponding subjective perspective. The first evaluation module is used to obtain the evaluation results of traffic events from the current subjective angle according to the simulation analysis of road distribution information, intentional driving information, and event information,...

Abstract

The invention discloses a semantic analysis-based traffic event evaluation method and system, a terminal and a medium, and relates to the technical field of intelligent traffic, and the key points of the technical scheme are that the method comprises the steps: carrying out feature extraction of voice information through a semantic analysis method, and obtaining subjective information; performing simulation analysis according to the subjective information to obtain a traffic event judgment result under the current subjective angle; judging whether the traffic event judgment results under different subjective angles are consistent or not; if so, selecting one of the traffic event judgment results as a final judgment result; and if not, establishing a traffic event judgment standard according to all subjective information or the re-acquired accident image information, and taking a traffic event judgment result with the highest similarity with the traffic event judgment standard as a final judgment result. Responsibility determination can be completed only by providing corresponding language information after a traffic event occurs, related personnel do not need to arrive at a site for processing, and meanwhile, the limitation of image acquisition is also overcome.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, more specifically, it relates to a traffic event evaluation method, system, terminal and medium based on semantic analysis. Background technique [0002] A traffic accident generally refers to an event in which a vehicle causes personal injury or death or property damage due to fault or accident on the road. The determination of the responsibility of existing traffic incidents generally requires the judgment of traffic police or professionals from insurance companies. During this process, waiting for a long time for traffic police or professionals is likely to cause road congestion, which is not conducive to the normal operation of urban roads, and is likely to cause secondary accidents. Events happen, so the realization of intelligent evaluation of traffic events is the current key research direction in the field of traffic technology. [0003] At present, the intelli...
