specific Embodiment approach 1

[0041] Specific implementation mode 1: The road operation safety grading evaluation system based on design consistency in this implementation mode includes:

[0042] The overall structure of the system is attached image 3 shown. The overall architecture of the system is composed of data layer, application layer and display layer;

[0043] The data layer is mainly for storage and analysis of original road design data and evaluation result output data, and supports file formats such as EXCEL, CSV and text files;

[0044] The application layer extracts and enters the data required in the evaluation process by accessing the data layer, and then performs corresponding processing according to the information transmitted by the receiving control module to realize the response to the operation input by the user of the display layer, and finally transfers the evaluation result data to the data layer storage;

[0045] The display layer includes the user command input interface and t...

specific Embodiment approach 2

[0064] Embodiment 2: This embodiment differs from Embodiment 1 in that the user interface control module is also used for inputting user evaluation parameters and visually outputting evaluation results.

[0065] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0066] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the database module extracts the road horizontal and vertical alignment data (the angle between the straight line and the curve. The plane alignment parameters; the maximum length of the straight line, the minimum length of the straight line Length; limit minimum radius of circular curve, general minimum radius, minimum radius without superelevation, circular curve length; transitional curve form, minimum length of transitional curve, curvature of transitional curve. Profile parameters: longitudinal slope gradient, longitudinal slope length, Vertical curve radius, etc.), road grade, speed and other control parameters required for evaluation, and data processing and analysis are performed according to the system evaluation process. Finally, the evaluation result data is stored in the relevant database.

[0067] Other steps and parameters are the same as those in ...

Abstract

The invention discloses a road operation safety grading evaluation system and evaluation method based on design consistency, and relates to a road operation safety grading evaluation system design andevaluation method, aiming to solve the problem of inaccurate evaluation results caused by insufficient consideration of design consistency in design of an existing highway operation safety evaluationsystem. The road operation safety grading evaluation system based on the design consistency comprises a user interface control module, a database module, a road section division module, a linear specification conformance inspection module, an operation speed prediction and correction module and a safety evaluation analysis module, wherein the user interface control module is used for realizing interactive control of a user, the database module, the road section division module, the linear specification conformance inspection module, the running speed prediction and correction module and the safety evaluation and analysis module. The road operation safety grading evaluation system is applied to the field of highway operation safety prediction.

Description

technical field [0001] The invention belongs to the field of road traffic safety, and in particular relates to the design and evaluation method of a graded evaluation system for road operation safety. Background technique [0002] Highways are an integral part of the transportation infrastructure system. Although the construction level of my country's road traffic infrastructure and the scale of road traffic network have been greatly improved, the scale of road mileage in my country has ranked first in the world, which has played an important role in promoting the development of my country's national economy. However, the road traffic accident rate in my country remains high. According to statistics, the direct property loss caused by traffic accidents in 2018 was as high as 1.385 billion yuan. Therefore, how to reduce road traffic accidents and improve driving safety is crucial to the development of the national economy. [0003] Whether the road alignment design is reaso...
