AI Technical Summary

Technical Problem

When evaluating the degree of influence of broken roads on vehicle speed, the prior art fails to effectively combine the specific degree of damage of the road surface as a consideration, resulting in low reliability of the evaluation results.

Method used

By obtaining reference to the damaged pavement information, including the width value of the lane, the depth value and area of ​​the pit slot, combined with the actual vehicle speed of the vehicle in these areas, the multi -linear regression fitting is performed to obtain the target fitting formula to evaluate the speed impact of the speed of the target road section section section section. Essence

Benefits of technology

It has improved the reliability of the evaluation result of the damage road facing the speed of vehicle speed. It can more accurately evaluate whether to renovate the road surface and provide a scientific basis.

Abstract

The present application discloses a method, device, equipment, and medium for evaluating the influence of a damaged road on vehicle speed. The method includes: obtaining the first lane net width value of a reference road section, as well as the first pit depth value and the first pit area of ​​a reference pit, the first vehicle speed, and the second vehicle speed; fitting multiple first lane net width values, multiple first pit depth values, multiple first pit areas, multiple first vehicle speeds, and multiple second vehicle speeds to obtain a target fitting formula; obtaining the second lane net width value of a target road section and the second pit depth value and the second pit area corresponding to the target pit; obtaining an evaluation result based on the second lane net width value, the second pit depth value, the second pit area, and the target fitting formula. The present application uses the damage parameters of the damaged road surface to comprehensively evaluate the influence of the vehicle speed, which effectively improves the reliability of the evaluation result compared to the evaluation scheme based only on the average speed of vehicles passing through the damaged road surface.
