specific Embodiment approach 1

[0035] Specific embodiment one: a kind of road safety evaluation system based on predicted accident rate grading described in this embodiment, said road safety evaluation system includes user interface control module, data extraction and management module, road segment division module, accident prediction module, Evaluation result feedback and output module, in which:

[0036] The user interface control module is used to receive and send user operation instructions;

[0037] The database interface of the data extraction and management module is connected with the data interface of the road design software, and data is extracted from the road design software, and the extracted data is stored in the database of the data extraction and management module;

[0038] The road segment division module is used to establish the road alignment of the prediction area according to the data in the database of the data extraction and management module, and divide the prediction area into road...

specific Embodiment approach 2

[0064] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the data extraction and management module is also used to save the prediction result of the accident prediction module and the analysis result of the evaluation result feedback and output module.

specific Embodiment approach 3

[0065] Embodiment 3: This embodiment differs from Embodiment 2 in that the data stored in the database of the data extraction and management module also includes data imported from files and data manually input by the user.

Abstract

The invention discloses a highway safety evaluation system and evaluation method based on prediction accident rate grading, and belongs to the technical field of traffic safety. The highway safety evaluation system solves a problem that there is no real-time and effective road safety evaluation system suitable for the conditions of China at the present stage, so that the potential safety hazards of a road cannot be found in time. According to the method, a data information base needs to be constructed; data required by an accident prediction model is extracted and input into a system; the safety level of a road is judged according to an output accident prediction evaluation result; and positions where potential safety hazards possibly exist are found; and the system can evaluate the safetycondition of the built road and can also evaluate the safety of the design scheme, and then potential safety hazards are eliminated as much as possible in the scheme design stage, and accidents and road reconstruction cost after the road is built are reduced. The safety evaluation result of the system has certain reference significance for decision and management of traffic, so that traffic accidents can be effectively reduced and prevented. The highway safety evaluation system and evaluation method based on prediction accident rate grading can be applied to the technical field of traffic safety.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a road safety evaluation system based on predicted accident rate classification. Background technique [0002] With the rapid development of my country's economy, the construction level of my country's highway transportation infrastructure and the construction scale of road transportation network have been greatly improved, and the highway mileage has increased by leaps and bounds. Coupled with the increasing number of automobiles, the accompanying traffic safety issues have aroused widespread concern. So far, the number of traffic accident deaths in my country has been among the top in the world for more than ten years in a row, among which road traffic accidents are far more serious than urban road traffic accidents, and road safety evaluation is urgent. [0003] Patent CN105138733A discloses a two-lane highway traffic safety evaluation method based on drivi...
